Bar "chart" - dynamic box-size

[Samwise]

Hi!

I would to have something like a horizontal side by side bar chart. But I can only put a chart in the page header or in the page footer.
I need this bars in the details like this:

Header:
myData theBar

Details:
10 -----------------------------
5 ---------------
1 --


In MS-Access I could solve this with a Box and a dynamic size of this box for each record. How can I do this in Crystal Reports XI?

Thanks
