Hello, I've got a question that schould be simple for you. I have a line
chart with data for today, but I have a problem, if I look the report at
3:00 PM then the scale max is set to 3:00, but I would like to see the
whole scale, from midnight to midnight
I used a source code from gannt chart which is pasted below:
function beforeGeneration(chart, icsc)
{
importPackage(Packages.org.eclipse.birt.chart.model.type.imp l);
importPackage( Packages.org.eclipse.birt.chart.model.data.impl );
importPackage( Packages.org.eclipse.birt.chart.util );
importPackage(Packages.java.util);
a1=icsc.getExternalContext().getScriptable().getGlobalVariab le( "a");
b1=icsc.getExternalContext().getScriptable().getGlobalVariab le( "b");
c1=icsc.getExternalContext().getScriptable().getGlobalVariab le( "c");
c2=icsc.getExternalContext().getScriptable().getGlobalVariab le( "c1");
rpctx = icsc.getExternalContext().getScriptable();
xAxis = chart.getBaseAxes()[0];
yAxis = chart.getOrthogonalAxes( xAxis, true)[0]
scale = yAxis.getScale();
scale.setMin( DateTimeDataElementImpl.create( new CDateTime(a1,b1,c1) )
);
scale.setMax( DateTimeDataElementImpl.create( new CDateTime(a1,b1,c2) )
);
seriesDef = yAxis.getSeriesDefinitions().get(0);
runSeries = seriesDef.getRunTimeSeries()[0];
}
but I get error message: INVALID MINIMUM SCALE VALUE 0 SPECIFIED FOR AXIS
TYPE LINEAR
Any idea??
Thanks in advance

Set the scale on the xaxis not the yaxis.
