I have my own type of data set with data similar to the following:
product | colour
prod1 red
prod2 green
prod3 red
prod4 blue
prod5 red
I would like to create a pie chart that shows that in this data set
there are three things with a colour of red, one green thing etc. There
could be a variable number of colours in the data set.
I have tried various aggregations but none of them seem to do anything.
Is it possible to produce the type of pie chart I want with BIRT 2.2? If
so, how do I do it?

Yes, that's something we should fix in the UI, since if you choose "count"
you don't really need to bind it to any column. Any value would work, it
will be ignored anyway, and the count will be used.
Thanks,
