CurveExpert Professional Changelog

What's new in CurveExpert Professional 2.7.1

Oct 4, 2020
  • CurveExpert Pro and Basic have had a mountain of under-the-hood modernization updates that are necessary to carry the products forward with future development. The underlying Python distribution has been upgraded to Python 3, and the UI toolkit has been upgraded. With this, the overall stability of the software is improved, and common problems like being unable to run the software from a directory that has "exotic" characters is possible. Also, the calculation speed has been nearly doubled because of the leveraging of optimized machine-specific algorithm implementations particularly for the nonlinear regression algorithm.
  • Two new graph themes have been introduced; Dark Pastel, and Light Pastel. These modern themes let you easily apply very attractive styling to your plots;
  • In addition to what has been discussed above, the following changes have been implemented:
  • Improvements to locale/region behavior; application now always conforms to region settings for numerical formatting.
  • SVG equations in documentation
  • General documentation improvements
  • Robustness fixes in the nonlinear regression algorithm; there was a lack of robustness of the initial guess caused an inability to evaluate the residual.
  • Two new graph themes: Dark and Light Pastel
  • Creation of over 700 unit tests for continuous integration
  • added the Python Sandbox to the Tools menu.
  • PDF documentation now included with the software along with HTML.
  • Added support for macOS High Sierra and Mojave
  • and the following defects have been addressed and are marked with the particular release numbers:
  • [2.7.0/2.2.0] Even if a plot's coloring was dark, a white border was imposed when that plot was saved as svg/png/jpeg/etc. Fixed.
  • [2.7.0/2.2.0] Changing visibility of graph title via the small dialog did not work. Fixed.
  • [2.7.0/2.2.0] Digitizer: points did not properly highlight on macOS, so point cannot be deleted. Fixed.
  • [2.7.0/2.2.0] Fixed bug where the contour sample would not open
  • [2.7.0/2.2.0] Improved UI in the graph theme manager
  • [2.7.0/2.2.0] fixed trial license manager not working on macOS
  • [2.7.0/2.2.0] fixed that points in key and number of columns in a legend could be erroneously set to zero
  • [2.7.0/2.2.0] fixed issues in the nonlinear regression picker dialog
  • [2.7.0/2.2.0] improved UI in the result details dialog
  • [2.7.1/2.2.1] fixed bug where sometimes built-in models would fail to import the first time they were accessed.
  • [2.7.1/2.2.1] fixed bug where reading in datasets over 5000 points would cause serious graphing problems.
  • [2.7.1/2.2.1] too easy to crash table generation dialog with too many points. Limits imposed to protect from this.
  • [2.7.1/2.2.1] removing rows is disallowed if the data set has none (spreadsheet)
  • [2.7.1/2.2.1] fixed some very small documentation issues
  • [2.7.1/2.2.1] fixed sorting errors in the graph interactivity section
  • [2.7.1/2.2.1] if a cxp document was saved with no data and read back in, it was impossible to add data to the dataset. Fixed.
  • [2.7.1/2.2.1] fixed an issue introduced in 2.7.0 where on a fresh installation on a mac, the graph themes were not installed correctly and were therefore not available.

New in CurveExpert Professional 2.6.5 (Jul 16, 2018)

  • This version adds the ability to run plugins from the command line, as well as correcting an error in both Dose Response Log Logistic models.

New in CurveExpert Professional 2.6.0 (Feb 9, 2017)

  • CurveExpert Professional has been updated today, which is a free upgrade for all existing customers. Adds the following features and fixes a couple of outstanding problems.
  • NEW: Five new Yield-Density models added (thanks Charles Tomkins for the model list), and previous Yield Density models have been moved to the Yield-Spacing family.
  • NEW: changed the strategy for the "Top Results" plot. It now always displays only the top results (the number of which is configurable in the application preferences). Previously, the plot would always add the top results from any new calculations the user might perform, which was confusing.
  • NEW: When right clicking a result, there is a new menu option "Add to New Plot" when appropriate. This creates a new plot and sends the result(s) there in one step. When a plot is created in this way, the title of the plot is that of the first result sent to it (for example, "Modified Exponential"). The "Add to Plot" option in the menu has been renamed to "Add to Current Plot" also.
  • NEW: Expand/Collapse buttons added in the Nonlinear Regression selection dialog, so that it is easier to select just a couple of families from the library.
  • NEW: Better robustness for 15 of the nonlinear regression models, so that the initial guess mechanism may be able to survive a zero in the x or y columns of the dataset.
  • RESOLVED: If the residual history had a NaN, the Convergence tab would not appear properly (with a small white box) in the result details dialog. Fixed.
  • RESOLVED: in some situations, obviously failed models were showing with a status of OK. Fixed.

New in CurveExpert Professional 2.5.3 (Dec 20, 2016)

  • NEW: Added ability for user to build table in multiple ways: from a file with the desired x values, from a xstart/xstop/npoints triple, from a xstart/xstop/dx triple, and from the current data in the dataset.
  • NEW: Added "Export Table" to the right click menu in the Results pane. This makes it easier to quickly create tables without having to open the Result Details dialog.
  • NEW: Added "Copy Parameters" and "Copy All Info" to the right click menu in the Results pane. This makes it easier to get parameters and model information out of CurveExpert Pro into another application (such as Excel).
  • NEW: improved the user interface in the Create Table dialog.
  • NEW: --license and --quit command line options added for administrators who desire to apply licenses in an automated fashion.
  • NEW: on a Mac, send the tip of the day text to the messages window.
  • RESOLVED: PS/EPS files were not correctly output under Windows. Fixed.
  • RESOLVED: unnecessary console window "flashes" eliminated when the program checks for new versions online
  • RESOLVED: Slight adjustment to the location of popup menu in the result control under Linux.

New in CurveExpert Professional 2.5.1 (Nov 25, 2016)

  • This release fixes odd behavior when closing some graph properties dialogs with the 'x' instead of clicking cancel, and also non-operation of the simple function definition and transformation dialogs in GraphExpert Pro (bug occurred under Windows only). Also, some missing library files in the CurveExpert Pro distribution are now included.]
  • The major change in this release is that both applications are now 64 bit, on all platforms. This is for compatibility going forward, and 64-bit operating systems have now been widely available for a number of years. If you are still running a 32-bit operating system, the last version of CurveExpert Pro you can use is 2.4.0, and the last version of GraphExpert Pro you can use is 1.4.0. These versions (and the versions below) are all 32-bit.

New in CurveExpert Professional 2.5.0 (Nov 17, 2016)

  • NEW: The software is now 64-bit.
  • NEW: Intel Math Kernel libraries utilized for greater processing speed
  • NEW: Under macOS, the application uses the Cocoa framework rather than the outdated Carbon framework This results in more modern/standard graphical interface elements and greater stability in general.
  • RESOLVED: The application would not start on OSX 10.11 (El Capitan) or 10.12 (Sierra). Fixed.
  • RESOLVED: Add retina support on macOS for retina displays. [bug 1527]
  • RESOLVED: Under macOS, the Help, Preferences, and About menu choices are now moved under the Apple menu as is standard. [bug 1942].
  • RESOLVED: Digitizer did not work correctly on retina displays. This has been fixed, with the caveat that the crosshair overlay and pink highlighting of points as they are pointed-at, has been disabled. [bug 1932]
  • RESOLVED: Crash when deleting a sorted dataset that was generated from a digitizer dataset. Fixed. [bug 1900]
  • RESOLVED: Background color of the number of divisions for minors control in the graph preferences dialog was miscolored under OSX. Fixed. [bug 1399]

New in CurveExpert Professional 2.4.0 (Jul 7, 2016)

  • NEW: added capability to perform nonlinear regressions; the user defines the formula, and GraphExpert Pro optimizes the parameters to fit the data.
  • NEW: added Lowess smoothing capability
  • NEW: added support for syncing the legend labels to component names. A new application preference has been added for this.
  • NEW: added ability to move components up and down via menu choices. Also added shortcut key documentation to right click context menu.
  • NEW: added support for weighting polynomial regressions
  • NEW: polynomial regressions and linear regressions now have appropriate statistics shown in the tooltip (standard error, correlation coefficient, etc).

New in CurveExpert Professional 2.3.0 (Jan 12, 2016)

  • NEW: Added the ability digitize datasets from a source image. The digitized data becomes the main dataset that is operated on in CurveExpert Pro.
  • NEW: added Savitzky-Golay smoothing
  • RESOLVED: when drawing a line on a log plot, the points were not evenly spaced in log scale. Fixed.
  • RESOLVED: transparency setting was lost from a contour once the graph properties dialog was exited. Fixed.
  • RESOLVED: import of noisy_sin.dat, which had special tags at the top of the file, gave these special lines as the column headers. Fixed.

New in CurveExpert Professional 2.2.0 (Nov 10, 2014)

  • NEW: large file/dataset support. Reading of large data files now takes a fraction of the time required previously, and multiple efficiency problems fixed in the dataset viewer and graphing components such that working with large datasets (1M rows and larger) is tractable.
  • NEW: added the ability to delete any or all curves on a graph that a right click occurred over.
  • CHANGED: better column header detection during file read; there is now a look-back from the start of the data to detect the column headers, so they need not be one line above the data.
  • CHANGED: when multiple files are dragged to the dataset control, they are now sorted by name before importing/hotlinking.
  • RESOLVED: NaN's generated in the logarithmic functions were not handled properly, leading to incorrect program behavior and possible hangs. Fixed.
  • RESOLVED: some older cxp files failed to read in properly, leading to difficulty when performing subsequent curve fits. Fixed.
  • RESOLVED: multiple graphing problems under OSX, caused by a faulty build, have been addressed.

New in CurveExpert Professional 2.0.4 (Mar 18, 2014)

  • NEW: The user can now insert leaders and trailers into the axis labels.
  • CHANGED: added warnings that display to the user if the confidence or prediction bounds cannot be computed at draw time.
  • RESOLVED: Can only paste a theme once.
  • RESOLVED: A single dollar sign, when displayed on the graph, sometimes did not display properly. Fixed.
  • RESOLVED: Drag and drop of a cxp file to graph doesn't work.
  • CHANGED: Added a way to change the license even on an already-licensed product.

New in CurveExpert Professional 2.0.3 (Mar 18, 2014)

  • CHANGED: Sped up file I/O significantly as long as locale-aware conversions are not used. Files read 4-6 times faster.
  • RESOLVED: intermittent "list index out of range" error when setting axis labels via a hotlinked file.
  • RESOLVED: In the German locale, the graph properties dialog would not respond to OK or Apply. Fixed.
  • RESOLVED: cloning an image that was in the background did not work correctly. Fixed.

New in CurveExpert Professional 2.0.2 (Mar 18, 2014)

  • RESOLVED: could not create a 2D contour plot when the current dataset was empty. Fixed. [4123]
  • RESOLVED: If a hotlink was created to a nonexistent file, the graphs were put in INVALID model, and they never recovered Fixed. [4128]
  • RESOLVED: Changing the number of columns in a hotlinked file is now not allowed. [4130]
  • RESOLVED: Graph malfunctions when selecting File->New and setting the number of independent variables to 2. Fixed. [4120]

  • RESOLVED: if a hotlinked 3D dataset is cut back to an empty file, indeterminate results. Fixed. [4129]
  • RESOLVED: Strange behavior from colorbar if a 3D plot (or contour plot) consisted of all constant z values. Fixed. [4131]

New in CurveExpert Professional 2.0.0 (Jun 17, 2013)

  • Plugins:
  • An exciting new feature has been added to CurveExpert 2.0, called plugins. Plugins allow you to automate repetitive tasks as well as integrate CurveExpert 2.0 into your own workflows. Several examples of plugins are included with the software, and the API's are described in the documentation that ships with CurveExpert Pro. And we don't try to invent our own scripting language; plugins are written in standard Python. Built-in modules include numpy (numerical arrays), scipy (scientific computing), and wxPython (GUI toolkit). These built-ins give you flexibility and power to compute and automate practically anything. Plugins are really only limited by your imagination; any Python module can be imported into a plugin, even those that you have installed externally to CurveExpert Pro. As an example of using a plugin is to automate the reading of several different datasets, perform analysis on each one in turn (say, compute a few nonlinear regressions), and write the results out to a file. Two screenshots are shown below that demonstrate the writing of a plugin, and the manager that is used to install, uninstall, enable, and disable plugins.
  • Polar graphs:
  • A new plot type has been added; it is now possible to plot anything on a polar axis. An example of this is shown below; all normal graph features are available also when working with a polar graph.
  • Hot links + direct import from Excel files:
  • Instead of importing your data files into CurveExpert Pro, you can now create a hot-link to the underlying text or Excel file. When the data in the text file (or Excel file) is updated, the data within CurveExpert Pro is automatically updated. Further, all results based on that data are updated. This very important feature allows you to keep only one copy of your data, which eases the data management burden. The hot link can either refer to a text file where the data resides, or it can refer to an area with an Excel spreadsheet where the data resides. Both .xls and .xlsx files are supported.
  • 3D/Contouring Graphing improvements:
  • In previous versions of CurveExpert Pro, one could contour only a continuous result. The contouring capability has now been extended to contouring discrete data (your dataset) as well, regardless of its regularity or structure. In addition to this, you can also now plot triangulated wireframes, solid triangulated surfaces, rectangular wireframes, and rectangular surfaces (carpets) of your data. In addition to this, it is now possible to draw a scatterplot of a 3D dataset with color shading of points that correspond to the selected colormap (which maps z values to a particular color). An example of six new plot types is shown below (click to see a larger version).
  • Other Graphing Improvements:
  • The graphing component in CurveExpert Pro has been improved significantly for a better user experience and more flexibility in your plot creation. A list of new graph features is below:
  • support for drawing arrows, lines, and shapes (rectangles, squares, ellipses, etc.) on a graph. Text inside the shapes is optional.
  • undo capability, which is a huge timesaver, and allows you to experiment with the appearance of a graph without fear of overwriting previous work.
  • ability to set the aspect ratio of a graph canvas.
  • ability to copy the underlying data from any curve; right click any curve and pick "Copy Numbers".
  • autoscale lock. This allows you to force the current graph extents to stay fixed, regardless of whether the data or results on the plot change.
  • ability to specify axis spacing by either amount or number of divisions, for both minor and majors.
  • a right click pan will now only pan the axis that the mouse is moving in.
  • ability to cut and paste a theme from on graph to another.
  • 10^x tick mark format; particularly useful on log plots.
  • "Clear all Series" added to graph right-click menu
  • A new application preference sets the maximum number of points to place on graph; this is very important for extremently large datasets. If a dataset exceeds the number of points allowed, the plotted points are intelligently "thinned" such that the character of the entire dataset is still displayed, but just with fewer visible points.
  • right click menu choices to move tabs in the "Data and Graphs" notebook tabs left and right
  • ability to lock marker color to the line color for a series
  • Other changed behaviors and minor additions:
  • Tooltips tell the reason for the colors in the results list, and give the stats for each curve fit.
  • Annotations no longer have the "Draw arrow only" option. Arrows should be drawn with the new arrow functionality.
  • annotation demo sample .cxp file
  • notebook selector now is not drawn every time the spreadsheet is revealed. The spreadsheet must have focus to be drawn.
  • new plots created are now named Plot #1, Plot #2, etc.
  • newly added annotations use the same properties as the last added annotation, for convenience.
  • "scale markers" in the graph properties dialog can now be a floating point number for more control, and it cannot be zero.
  • color cycles are now saved as a part of the graph themes. Old graph themes will still work, but will not modify the existing line colors or markers in the plot.
  • "Line/Markers" page in the graph properties dialog changed to "Series".
  • Themes in right click menu that are offered, are now sorted.
  • autoscaling has been improved in intelligence and robustness.
  • when zoom/pan buttons are depressed, other buttons on the graph toolbar now enable/disable appropriately. It is now no longer allowed to pull up property dialogs via the keyboard mouse when a zoom/pan is active.
  • double clicking a series in a plot now only raises the properties for that series; not the ones for the rest of the graph too.
  • many tooltips added in the axis panel in the graph properties dialog.
  • Font on the notes page is nicer and larger, especially on OSX.
  • performance enhancements in the graph drawing
  • in the graph properties dialog, the OK and Apply buttons do not enable until some property is actually changed. This saves needless graph redraws if the user does not change anything.
  • the drawing order of series is now determined by their ordering in the legend.
  • the ESC key now releases the selected object in the graph.
  • disabled distance alpha shading on 3D scatter plots.
  • items in the Window menu are now alphabetized.
  • the plot is now drawn larger on a printout than it was previously
  • the entire CurveExpert Pro window is now a drop target for files.
  • Bugs resolved:
  • in the result details dialog, the surface was always drawn with a red solid linestyle, which was unattractive. The line has been changed to thin/black.
  • could not right click on initial guess plot in order to change graph properties. Fixed.
  • small gap between the annotation arrow and the shape that it is coming from. Fixed.
  • File import dialog resized in a very odd way. Fixed
  • odd text appearing in initial guess dialog parameter list. Fixed
  • decreased overall memory usage of graphs
  • using the keyboard to change notebook pages in the Graphs and Data pane could lead to some very ill effects
  • since the alpha control has no effect on a data 3D scatterplot, is it now disabled.
  • a dataset with standard deviation stems did not obey visibility flags properly. Fixed
  • incorrect autoscale if only bars on a plot
  • if there is a syntax error in the graph properties dialog, the error information bar causes a little bit of an ugly sizing problem. Fixed.
  • colorbar is invisible on a 3D plot until the graph properties are invoked once. Fixed.
  • Under OSX, double clicking a cxp document would load CurveExpert Pro, but not load the document. Fixed.
  • When a pan was over, the continuous results were not updated. Fixed.
  • A few dialogs did not have correct tab traversal order. Fixed.
  • Documents opened via a double click didn't get saved in the most-recently-used list. Fixed.
  • better reporting for a failed file read, if there are wrong number of items in a row.

  • RESOLVED: buttons on graph toolbar slow to redraw after hovering the mouse over them. FIxed
  • RESOLVED: a tick mark was sometimes lost from the end of an axis due to tolerancing issues. Fixed
  • RESOLVED: under Windows 8, certain fonts would not cooperate with mathtext, Arial being one of them. Fixed.
  • RESOLVED: The range for a 3D preview plot was set by the first result pointed to and never updated again. Fixed
