Script the label interval for a bar chart

I have built a parameterized bar chart that will lay more or less bars depending on a parameter called 'DataSize'. Depending on this parameter I can end up with too many labels and then Birt will drop some as it needs to render the chart. Is there a way to set the Interval field (defined in the label screen of the X-Axis) using a script that checks the value of the parameter to decide what value to assign it.

I am using BIRT 2.2.2 and know the report designer GUI well but I have not done any kind of scripting. Can someone plase help me with this? if you can spare the time show me the script and explain how to set it.

Best Regards.

I just posted an example of how to do this using a report parameter and script.

Several places discuss Scripting:

You can also look at the books:

And several BEX items containt PPTs that discuss it:
