Disabling legend when series value is 0

bhavyasingh.k@gmail.com

<p>Hi,</p>
<p> </p>
<p>I am using BIRT 3.2.21 . I am new to it. I am facing an issue where i have to disable the legends when any one of the bar column value is 0.  for example if i have two series and one of the series value is 0 then i have to disable the legend.</p>
<p>Please help.</p>

<p>Assuming the chart is SVG, this can be accomplished using some code in the charts onRender method.</p>
<p>Below is the code I use in the attached example that demonstrates this.</p>
<p>See the attached example for more detail.</p>

seriesWithoutValuesArray=[]; //Set array variable

function afterDataSetFilled(series, dataSet, icsc){ //Happens before beforeGeneration
importPackage(Packages.org.eclipse.birt.chart.util);
ps = PluginSettings.instance();
dsp = ps.getDataSetProcessor(series.getClass());
if ( !parseFloat(dsp.getMaximum(dataSet)) > 0) //If dataSet value is not greater than 0
seriesWithoutValuesArray.push(series.getSeriesIdentifier()); //Push Series name to array
}

function beforeGeneration( chart, icsc ){ //Happens after afterDataSetFilled
yAxis = chart.getPrimaryOrthogonalAxis(chart.primaryBaseAxes[0]);
for (var i = 0; i < yAxis.seriesDefinitions.size(); i++) //Loop through series's
if (seriesWithoutValuesArray.indexOf(yAxis.seriesDefinitions[i].series[0].seriesIdentifier) > -1 ) //If series name is in the Series array from afterDataSetFilled
yAxis.seriesDefinitions[i].series[0].visible = false //Hide the series
}
