What's new in WZGrapher 0.95
Jun 6, 2013
- Fixed GDI leak under Windows 9x/ME. Could lead to a crash after frequent updates of the coordinatesystem.
New in WZGrapher 0.94 (Jun 6, 2013)
- Supports graphs in polar coordinates, also for ordinary differential equations.
- Mousegesture duration no longer infinite (now 1.5 seconds).
- Detailed main help can now be invoked directly from function input dialogs(per F1 key).
- Changes to axes titles can be applied immediately, while the dialog is still open.
- Messagebox that requests confirmation if user changes default values for x- and y-range.
- Up to 1024 scroll/zoom undo steps.
- Rendering of coordinatesystem is worlds faster, especially perceptible when also subgrid is displayed.
- Drawing the zoom selection rectangle is faster (perceptible on slower machines).
- Some improvements on the rendering modules for graphs and help windows.
- Improvements on the printing engine (e.g. leaves margins).
- Fixed: Parallel installed versions < 0.91 won't crash at startup anymore (this is actually a bug in those old versions, the new version just doesn't "uncover" it anymore).
- Regression: Results y of cot(x) were offset by -pi.
New in WZGrapher 0.93 (Jun 6, 2013)
- New: Derivative operator d(). Computes the derivative of the expression within the parentheses. Examples: y=d(x^2) or y=1/12*d(d(x^4)). Supported maximum nesting level is 3 (allows to compute up the 3. derivative).
- Main dialogs and thus function input textedits can be resized horizontally. The app now remembers these sizes and positions also when being restarted.
- Main and help window can be KDE-like dragged by simultaneously pressing the ALT key.
- Accuracy of drawn integral solution curves further improved through pixel alignment of the lower integration limit.
- Zoom functionality regards whether the concerned range (x or y) is displayed in units of PI.
- Select box "Draw 1. derivative" on the dialog for normal functions removed. The new derivative operator d() has made this option needless.
- Single-value-calculator bug from V. 0.92.7 was not yet properly fixed, did occasionally evaluate y' to false infinite.
- Fixed: Resizing the function input dialog vertically didn't work properly.
- When selecting a zooming rectangle, stretching the rectangle beyond the left window boundary didn't work correctly.
New in WZGrapher 0.92.9 (Jun 6, 2013)
- Parts of core code rewritten, e.g. the coordinate system engine and the
- functions for formatting and drawing numbers.
- Draws now also sub-tickmarks.
New in WZGrapher 0.92.8 (Jun 6, 2013)
- Graph image copied to clipboard via CTRL+C is now also GIMP-compatible.
- Consider that in GIMP you cannot paste external data from the clipboard via CTRL+V; use "Edit"->"Paste From Clipboard" instead.
- Mousecoordinates-tooltip can display values in units of Pi.
- Fixed: Selecting a zooming rectangle with the mouse could not be canceled by pressing [Esc].
- Bug introduced with v 0.92.7: Single-value function calculator did not always print the first derivative value and could occasionally crash.
- Zoom functionality of help windows disabled (didn't work properly with some video cards - I'll try to fix that later).
New in WZGrapher 0.92.7 (Jun 6, 2013)
- Draws optionally also the 1. derivative, of normal functions as well as of ordinary differential equations.
- ODE-solving function calculator: Inserts initial values into the value tables when these are copied to the clipboard.
- Supports XP styles (themes) when running on Windows XP.
New in WZGrapher 0.92.6 (Jun 6, 2013)
- Improved file name handling, e.g. filename is now set to "untitled.wzg" if not yet userspecified.
- Fixed: Out-of-bounds memory reading could occur with binary files corrupted in a certain manner (missing zero-bytes in ascii section of file).
New in WZGrapher 0.92.5 (Jun 6, 2013)
- Coordinates at mousepointer displayed also while selecting a zoom rectangle.
- Zoom selection rectangle entirely visible also when expanded beyond the app's window boundaries.
