All Bar Charts

This section shows common settings available to all Bar Charts. A Simple Bar Chart is used only for illustrative purposes.

jCharts allows you to specify the width of the bars in the chart relative to the amount of space allocated to each scale item. This is specifed by a percentage value, 1=100%, .5=50%, etc...

barChartProperties.setWidthPercentage( 1f );				
			

jCharts allows you to specify the 'outline' properties of the bars. The default values are to show a one pixel wide, black outline. This is set on the BarChartProperties Object, from which all Bar Chart Types extend.

barChartProperties.setShowOutlinesFlag( true );
ChartStroke outlineChartStroke= new ChartStroke( new BasicStroke( 2.0f ), Color.red );
barChartProperties.setBarOutlineStroke( outlineChartStroke );
			

Each of the Bar Chart Types can be plotted Horizontally by simply passing a flag to the AxisProperties Constructor.

AxisProperties axisProperties= new AxisProperties( true );				
			

It is possible to display value labels on your Bar and Clustered Bar charts, but not Stacked Bar Charts. To do this, add a ValueLabelRenderer to the BarChartProperties Object by calling the addPostRenderEventListener( PostAxisValueRenderListener ) method.

You can set the Font and Paint used for the Values on the ValueLabelRenderer Object.

ValueLabelRenderer valueLabelRenderer = new ValueLabelRenderer( false, false, true, -1 );
valueLabelRenderer.setValueLabelPosition( ValueLabelPosition.AT_TOP );
valueLabelRenderer.useVerticalLabels( false );
barChartProperties.addPostRenderEventListener( valueLabelRenderer );
