Hi,
I'm working with Birt 2.1.2. I have a report in which I display a chart
multiple times (it is inside a table group in a table). Each time, the
chart inherit the dataset from the table, and displays its entries. The
chart is a flipped bar chart. Is there a way to change dynamically the
chart size in order to show different dataset sizes?

For example, I have a data set with 2 columns NAME, VALUE, and a table
grouped by NAME. Consider this case (VALUEs aren't important):

NAME VALUE
a 1
a 12
a 41
a 541
a 61
a 231
a 41
a 541
a 1
a 31
a 1
a 12
a 11
b 25

In this case, my report will display 2 charts, one for "a" with 13 bars,
and one for "b" with 1 bar. Is there a way to resize the chart in order to
have small charts for small amounts of bars and higher charts for higher
number of bars? In my case, the bar number varies from 1 to 200 ca.
Choosing a static size that allow 200 bars to be displayed clearly, will
result in awful enormous charts in the case of only one bar.
Any suggestions?
Thanks!
