Assign color to stacked bar series

Hi, I would like to know how to assign a color to a bar series through the charting API in Java. The series are stacked and I would like to select one of 2 colors for each based on an attribute of the values.

Thanks!

Hi Terry, 
 
Since you want to change the colors based on values, then you should look at scripting for the chart. 
 
First, look at this example where the bar colors are changed based on values: 
<a class='bbc_url' href='http://www.birt-exchange.com/modules/wfdownloads/singlefile.php?cid=2&lid=276'>http://www.birt-exchange.com/modules/wfdownloads/singlefile.php?cid=2&lid=276</a> 
This example uses the chart inside a BIRT report design but makes it easy to test this way. 
 
Once you have a handle on how that works with the BIRT Designer, then you can use the setScript method on your chart with a similar script to have it work only with the Chart Engine API.

Thanks Virgil, I have gotten it working with adding a script. I also have another question. I am using SWT and I have a table with a list of items. These items are presented in two pie charts and a bar chart. Is there a way where I can highlight the part of each chart that contains the item that is selected on the table?

Thanks!
