<p>Hi<br>
I'm working on a meter chart that shows me the count of each string in a column of a dataset<br>
so to set dynamicaly the scale I used the beforeGeneration method of the meterchart and the onfetch method of the dataset</p>
<p><strong>onFetch script:</strong></p>
<p>reportContext.setPersistentGlobalVariable("Maxpgs", row["pgs_total"].toString() );<br><strong>BeforeGeneration script:</strong></p>
<p>function beforeGeneration( chart, icsc )<br>
{<br><br>
importPackage( Packages.org.eclipse.birt.chart.model.impl );<br>
importPackage( Packages.org.eclipse.birt.chart.model.type.impl );<br>
importPackage( Packages.org.eclipse.birt.chart.model.attribute );<br>
importPackage( Packages.org.eclipse.birt.chart.model.attribute.impl );<br>
importPackage( Packages.org.eclipse.birt.chart.model.data.impl );<br>
importPackage(Packages.org.eclipse.birt.chart.model.component.impl);<br>
<br>
seriesDef = chart.getSeriesDefinitions().get(0);<br>
meter1 = seriesDef.getSeriesDefinitions().get(0).getRunTimeSeries().get(0);<br>
mdial = meter1.getDial( );<br>
mscale = mdial.getScale( );<br>
mscale.setStep( 50 );<br>
mscale.setMin( NumberDataElementImpl.create( 0 ) );<br>
max=icsc.getExternalContext().getScriptable().getPersistentGlobalVariable("Maxpgs")<br>
mscale.setMax( NumberDataElementImpl.create( max ) );<br>
<br>
}</p>
<p>it work perfectly when i don't use the optional grouping, but when i use the grouping which allow me to count the number of each string of that column, it set the maximum scale only for the first instance of the chart and let the others with the default value which is 1</p>
<p>So How can i set the Max Scale for all the instances of the meterchart<br><br>
