Hi,

i have a question how to create a dynamic chart on a
table that is growing each month. I want a chart that
is showing the revenue of each category per month.
An example table is given below.

Date Position Category Price
05.03.2007 eggs food 2
26.03.2007 beer food 10
15.04.2007 nails utils 5
25.04.2007 oil food 1
30.04.2007 hammer utils 15


Thanks,
René
