I am trying to build an Application/ web app that would allow users to dynamically set limit/expand a date range on a standard chart. The data is stored in Excel 2003 and would be hosted online eventually using xml to post. Right now I have charts posted that are basically just pictures and I would like to allow users to modify them limitedly if needed. I know it can be done but I'm not exactly sure how to tie the buttons on the VB form to the excel data.

any help would be MUCH appreciated.
