- Visualize up to six functions simultaneously. All the usual functions can be called: they're all written on a virtual keyboard.

On a given function, others can be called, so it is possible to associate or compose functions. - Numerical sequence plotting, they can be defined by a recurrent relation or explicitly.
- Parametric equation plotting. The curves can be animated, with adjustable smoothness (frame rate) and speed (ms per step).
- Experimental data plot and polynomial fit (regression). Data can be imported/exported from a CSV file.
- Parametric plot for functions, sequences and parametric equations: the parameter symbol to use is "k".
- Plot tangents: they can be moved and resized simply with the mouse.
- Plot derivatives and antiderviatives.
- Print the graph, with these options :
- Choose the size and the position of the graph on the sheet.
- Print in color or gray-scale.
- Export on a PDF file.
- Export to all common image formats (png, jpeg, tiff, gif...).
- Display a table of values with different options.
- Navigate on the graph :
- Select a curve to display the coordinates of its points.
- Zoom/unzoom on each axis separately or together, with the mouse on a point, or on a rectangular region.
- Move the graph.
- Customize the presentation :
- Change all the colors: axes, background, functions...
- Adjust the plotting precision. Note that it will also affect rendering speed.
- Show/hide a grid.
- Activate/deactivate curves' smoothing.
- Plot the graph on an orthonormal basis.
