<p>Hi glo_fr</p><p> </p><p>Thanks for your answer...in part yes but what I want to do is defining two "regions" in my dial (or meter) chart...</p><p>I see here it is possible with actuate here</p><p><a href="
; (code at the end of this message) </p><p> </p><p>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 4.3.1</p><p>If not possible I would like to know because I search since 2 days....</p><p> </p><p>Thanks in advance for you answer !</p><p> </p><p>Vincent</p><p> </p><p> </p><p>>>>></p><p> </p><p><em>Region Events</em>
You can customize the colors, transparency, labels, and range values of any region using the beforeRendering or beforeDrawRegion scripts. See the example below.
</p><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>
