Is there already a python package allowing to graphically edit the graph of a function?

A:
Chaco is designed to be very interactive, and is significantly more so than matplotlib. For example, the user can use the mouse to drag the legend to different places on a plot, or lasso data, or move a point around on one plot and change the results in another, or change the color of a plot by clicking on a swatch, etc.

This is interesting, I will investigate further.

Great! I think I found it in the `edit_line` example of Chaco: http://code.enthought.com/projects/chaco/docs/html/annotated_examples.html#edit-line-py

tom10, thank you for sharing this. The Chaco FAQ offers a comparison with Matplotlib: http://code.enthought.com/projects/chaco/docs/html/user_manual/faq.html. This company, Enthought, is also the primary sponsor of Scipy.

This looks more like plot/figure editing, whereas I would rather interpret 'function/graph editing' as spline editing. Does Chaco support higher orders of interpolation or just line graphs?

@Maleev - Yours is an interesting question, but to me it seems different than the OP's. You might want to ask it as a separate question if you're looking for a package that will do this. (Most scientific graphing packages that I know of plot straight lines between the data points rather than more elaborate interpolations.)
