I'm constrained to using BIRT 2.2.1 by my implementation ...
I have a stacked bar chart with two series. I'm printing the value of
the series on the bar with a series value label.
If the second series is zero for a particular x-axis value, I get a '0'
printed on the bar chart. I'd like to be able to make that bar (and
label) not visible if the value of the bar is zero.
I've seen some other posts about highlighting a bar based on a parameter
and about hiding a series altogether, but I've been struggling with
making individual bars for a series not visible if their value is zero.
Thanks

Dave,
I just posted an example of this to dev share:
http://www.birt-exchange.org/org/devshare/designing-birt-rep orts/1245-hide-one-bar-in-a-chart-using-script/
The report is written in 2.5.2 but I posted the scripts in the comments
which should work for 2.2.1. Basically I just set the bar to transparent.

Jason,
Great!!
This works beautifully for one of my charts ...
The other one, however, I've made my life more difficult by customizing
the label.
One of my charts has Y series Grouping and I've set the label with the
Value Data and Value Series Name.
So, I'm guessing that somehow overloads the label - the same scripting
that works so well for the simpler case has no effect ... but, other
than that, I'm lost.
Thanks

Ahhhh! ....
OK .. I've figured out where I went sideways ....
I was comparing dph.getDisplayValue() == 0 .... not
dph.getOrthogonalValue == 0 in beforeDrawDataPointLabel. Once I
corrected that, things worked as expected.
Thanks
