A wing chart ( or tornado chart ) is a special type of bar chart ( or column chart ), where two bars ( or columns ) are spread over both sides of the axis. The wing chart is useful to compare two categories of data and to provide decision makers with a quick overview.
The <Bar2DWingChart> element tag is used to create a bar-type wing chart in KoolChart, and the series element tag for the bar-type wing chart is <Bar2DWingSeries>.
If you want to create a bar-type wing chart with multiple series data, create as many <Bar2DWingSeries> element tags as you want as a child node of the <series> element tag which is a child node of the <Bar2DWingChart> element tag.
... <Bar2DWingChart ... > ... <series> <Bar2DWingSeries xField="leisure1" xFieldOpp="leisure2" ... > ... </Bar2DWingSeries> <Bar2DWingSeries xField="self1" xFieldOpp="self2" ... > ... </Bar2DWingSeries> </series> ... </Bar2DWingChart> ...
|xField||The xField attribute determines the field name of the right wing of the horizontal axis ( horizontalAxis ).|
|xFieldOpp||The xFieldOpp attribute determines the field name of the left wing of the horizontal axis ( horizontalAxis ).|
