Bug 154093 Performance problem when rendering a chart with 1800 datapoints
I'm having some performance issues when I render 1800 datapoints in a chart. Rendering 1800 data points in a table is fine. My report just contains a simple line chart that is bound to a csv file. The csv file contains 1800 datapoints. I will attach the report template file and csv file.

protected void ungroupPrimitive( PrimitiveRenderEvent pre, boolean drawText )
	{
		if ( _iun == null )
		{
			logger.log( ILogger.WARNING,
					Messages.getString( "exception.missing.component.interaction", getULocale( ) ) ); 
			return;
		}
		
		if ( pre.getSource( ) instanceof StructureSource )
		{
			StructureSource sourceObject = (StructureSource) pre.getSource( );
			final Series series = (Series) getElementFromSource( sourceObject,
					StructureType.SERIES );
			if ( series != null )
			{
				if ( drawText )
				{
					svg_g2d.popParent( );
					svg_g2d.popParent( );
				}
				else
				{
					svg_g2d.setDeferStrokColor( null );
					svg_g2d.popParent( );
