Question: Graphical application for a webpage, allowing graphic curve manipulation

Hi all.

I want to make a graphical application for a webpage, showing curves with a certain number of points on X axis (about 10 or 15), and some sort of “handles” on curve values (for every curve, one to one corrispondence between them and points on X axis), allowing to move them from a minimum to a maximum, graphically (i.e., by dragging and dropping them vertically); initial values should be read from a CSV file, and rewrited there after a “save”, that need to be done inside the application.

X axis values are estabilished in CSV file, and should not be editable graphically.

Curve values are given from two tables, but not every data are shown at the same time: just one row a time. It should be possibile to select the row considered: in the example shown in images, Canale 2 contains all zero values for curves, and is shown the result for selected position 0. The user has to be allowed to change position for every value from 0 to 9.

Is that possible with Maple?

Thanks in advance.
