Hi glo_fr Thanks for your answer...in part yes but what I want to do is defining two "regions" in my dial (or meter) chart...I see here it is possible with actuate here<a href="; (code at the end of this message) but I don't find how to put function beforeDrawRegion( region, fgsc ) or to use function beforeDrawMarkerRange( axis, markerRange, icsc ) instead of... on Birt Community 4.3.1If not possible I would like to know because I search since 2 days.... Thanks in advance for you answer ! Vincent >>>> Region Events
You can customize the colors, transparency, labels, and range values of any region using the beforeRendering or beforeDrawRegion scripts. See the example below.
<pre>function beforeDrawRegion( region, fgsc ){ if( region.getLabel().equals("A") ){ region.setColor("00ff00"); } //Display value range of region. region.setLabel( "(" + region.getStartValue() + ", " + region.getEndValue() + ")" ); }function beforeRendering( gadget, fgsc ){ //First Region gadget.getRegion().get(0).setEndValue(25); //Second Region gadget.getRegion().get(1).setStartValue(25);</pre>

Something like this ? I've done it quickly on OS.Just change the value in the dataset and put a better radius than this one
