showing/hiding a series based on data values? [message #698911]

Hi,

I have a chart that has a series that uses data value X. I would like to hide the entire series legend entry and all (ie., like it didn't exist) if the first data value of X is null. How can I best do this?

I took a look at:
http://www.birt-exchange.org/org/devshare/designing-birt-reports/1289-remove-chart-series-based-on-parameter/
from another post. It gets me close in that it allows me to remove the series, but now the issue is that the condition for removal is derived from a dataset not a report parameter and I don't think I have access to this in the beforeFactory method of the report.

I could put a hidden table in the report and set a global parameter but I'm not sure that this would be done in the correct order?

Mike,

You can move the code from the beforeFactory to the beforeGeneration of
the chart like:

function beforeGeneration( chart, icsc )
{
//to get the reportContext use
//rpCtx = icsc.getExternalContext().getScriptable();
//rpCtx.getParameterValue(.. or rpCtx.getGlobalVariable
//to decide which series to remove
xAxis =chart.getAxes().get(0);
yAxis1 = xAxis.getAssociatedAxes().get(0);

//yAxis1.getSeriesDefinitions().remove( 1 );
//yAxis1.getSeriesDefinitions().remove( 0 );
}
