configure js application

I am wanting jsxgraph - [login to view URL] - configured to allow students type in data and having jsxgraph display the data as various types of graphs. Specifically I would like students to enter single variable data (x) and produce a line chart and a bar graph here - [login to view URL] and a pie chart here - [login to view URL] I would also like two variable entry of data (x,y) to produce a scatter graph here - [login to view URL] (this one already allows user data so no work here) and a scatter graph that shows the regression line here - [login to view URL] Thanks Richard
