In the chart editor, you can go to the "format data" tab, then to the value series section, click on the "labels" button at the bottom, delete the "value data" option from the values window, then from the dropdown below the window, choose the percentage option and add it. This will show your pie chart labels in percentage.

As for programatically, do you mean building the chart from scratch? Or do you mean changing which option is used in script?

Hi williams,

can you tell about the optional y series grouping option in birt charts.how to use that

where exactly it is used.can you please explain me with an example.

If you put a value in the optional y-series grouping, it creates a series for each value of that field, for your chart. Say you have x-axis field "customer" and y-axis field of "dollars spent". Then, say you have another field that is year that tells which year they spent this money. If you don't use the optional grouping, you'd have a chart that shows each customer's dollars spent for all years. If you put the year field as the optional grouping, there would be a bar for each year, for each customer. Hope this makes sense.

Hi williams,

Thanks for clarifying my doubt.i have another small doubt,please clarify me.

I attached a image of a chart that displays three bars for every month.if number of months are less,
the bars are coming in good size.if the number of months are more,then bars are displaying without space between them.due to this values of bars are displaying with out space.

I increased chart witdth and nothing worked for me.how to increase the spaces between individual bars.

please once look into the image once.

thanks,
giridhar

Take a look at this post in the devShare. It shows how you can resize your chart based on the number of bars:

I just noticed that this works with xls, but not xlsx. Any suggestions?
