Re: [jCharts-users] Problem in Image map generation

[Travis R. <tra...@ec...>]

Probably easiest if you do it, but I looked and I think it's here in 
verticalPlot():

if( rectangle.height != 0 )
                {
                    g2d.fill( rectangle );

                    if( barChartProperties.getShowOutlinesFlag() )
                    {
                        barChartProperties.getBarOutlineStroke().draw( 
g2d, rectangle );
                        g2d.setPaint( iAxisChartDataSet.getPaint( 0 ) );
                    }

                    //---if we are generating an ImageMap, store the 
image coordinates
                    if( axisChart.getGenerateImageMapFlag() )
                    {
                        String label;
                        if( axisChart.getXAxis().getAxisLabelsGroup() != 
null )
                        {
                            label = 
axisChart.getXAxis().getAxisLabelsGroup().getTextTag( i ).getText();
                        }
                        else
                        {
                            label = null;
                        }

                       * axisChart.getImageMap().addImageMapArea( new 
RectMapArea( rectangle,
                                                                        
                             iAxisChartDataSet.getValue( 0, i ),
                                                                        
                             label,
                                                                        
                             iAxisChartDataSet.getLegendLabel( 0 ) ) );*
                    }
                }

Should move that addImageMapArea out of the:   if( rectangle.height != 0 
) { block so it adds regardless.
