Bug 144077 Throw exception when generate SVG chart which has inteactive
There is a program mistake in "org.eclipse.birt.chart.device.svg" project. In "SVGInteractiveRenderer" class, "findCategorySeries" method, "getSeries( ).get( 1 )" should be changed to "getSeries( ).get( 0 )". It will throw exception when generate SVG chart which has inteactive. And i find this in 2.1RC3a.

				elSE = sd.getSeries( );
				for ( k = 0; k < elSE.size( ); k++ )
				{
					se = (Series) elSE.get( k );
					if ( seRT == se )

						bFound = true;
