Graphs in a form

[Marty]

I want to put a line graph, (OR ANY GRAPH) in a customer
form that shows their average purchases over a given
period of time. I can use the functions just fine to put
this information in text boxes, but cannot figure out how
to take these text boxes and make a graph out of them.

For instance:

TextBox1: 45
TextBox2: 60
TextBox3: 80

Graph this in a form in pie chart, line chart, whatever.
It doesn't work for me. I just get the TextBox1 total and
no graph. What's wrong? Any help will be appreciated
very much!
