A wing chart ( or tornado chart ) is a special type of column chart ( or bar chart ), where two columns ( or bars ) 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 <Column2DWingChart> element tag is used to create a column-type wing chart in KoolChart, and the series element tag for the column-type wing chart is <Column2DWingSeries>.
If you want to create a column 100% wing chart, set the value of the type attribute in the <Column2DWingChart> element tag to "100%"
... <Column2DWingChart type="100%" ... > ... <series> <Column2DWingSeries yField="male1" yFieldOpp="male2" ... > ... </Column2DWingSeries> <Column2DWingSeries yField="female1" yFieldOpp="female2" ... > ... </Column2DWingSeries> </series> ... </Column2DWingChart> ...
|type||The type attribute determines the representation type of multiple series bar chart. The valid values are "clustered", "overlaid", "stacked" and "100%". The default value is "clustered".|
|yField||The yField attribute determines the field name of the upper wing of the vertical axis ( verticalAxis ).|
|yFieldOpp||The yFieldOpp attribute determines the field name of the lower wing of the vertical axis ( verticalAxis ).|
|lineToEachItems||The lineToEachItems attribute determines whether or not to draw the connecting line between data points.|
