Chart legend spacing of displayed values - fixed??

b2tech

Hello:
[Using BIRT 3.7}

Has anyone figured out how to change the spacing of the values presented -within- a legend? I have a vertical bar chart that has ten values displayed in a horizontally oriented legend that is set to render below the actual chart.

These values are too long (run under the next value) and it appears that Birt always -evenly- spaces all the legend entries.

I have tried:

icsc.getChartInstance().getLegend().setHorizontalSpacing(25);

in the chart's onRender beforeGeneration(chart, iscsc) area and that did nothing.

I also tried:

chart.getLegend().setHorizontalSpacing(25); and that did not work either.

Note: (My code below may be affecting the above issue or... maybe not)

I already have code for this chart under the function beforeDrawLegendItem( lerh, bounds, icsc ) that will populate the legend values from external variables and also hide the legend value(s) when they are not supplied.

// Evaluate the chart number being layed out.
// Then grab the correct persistent global variable holding the chart legend value for each series
var varone = icsc.getExternalContext().getScriptable().getPersistentGlobalVariable("testcnt");

// First series labels
if( lerh.getLabel().getCaption().getValue().compareToIgnoreCase("Series 1") == 0 ){
var slabel = icsc.getExternalContext().getScriptable().getPersistentGlobalVariable("seriestitle-" + varone + "-1");
if (slabel != ""){
lerh.getLabel().getCaption().setValue(slabel);
}
else {
bounds.setHeight(0);
bounds.setWidth(0);
lerh.getLabel().setVisible(false);
}
}
.....etc...

Any help would be greatly appreciated.

Can you reproduce with a sample report that we can run?
