qtGrace

qtGrace is a tool to make two-dimensional plots of numerical data, generate graphs and analyze the results. It's packed with all sort of neat features and tools, all nicely arranged in a very comprehensive graphical interface with lots of tools at hand.

The application doesn't really install on your device, simply run the executable file from the folder and start using this. This is a nice thing, since it means that it doesn't take up space on your device and you won't have trouble removing it.

QtGrace comes with some sample files which you can load in order to check out its features.

It allows you to cut sections of files and draw on the image. You can create simple graphs, sets, fit curves and more. Besides reading in data files, Grace has an extensive scripting language with a large number of math functions built in.

These function include the basic add, multiply, square root, etc, and also the cephes library of higher order math functions like Bessel functions and the gamma function.

Grace supports a large number of command line options which allow the user to control the appearance and placement of graphs.

This can be very useful if you want to use it to quickly print something without going through the GUI, use it within a script to automatically generate graphs, or have a plot come up already configured which can be much quicker than going through the GUI menus.

You can rotate sets around an arbitrary axis perpendicular to the canvas (e.g. the Z-axis). Also it is possible to scale sets and translate them. When you're done working on your project, you can save it in a certain directory on your computer or in a certain format.

In conclusion, qtGrace is a very nice application that you can use in order to create graphs and make all sort of changes to them.
