Bi-Directional Bar Chart
To create a bi-directional bar chart, follow the steps below:
-
Convert half of the data source values from positive to negative. In this demo, the
malepercentages are negative, while thefemaleare positive. -
Implement a rotated stacked bar chart. Use the commonSeriesSettings object to specify the type and the argumentField property (
agein this case). Set the rotated property totrue. -
Declare two objects in the series array: one for negative values, the other for positive. Specify the color, name, and valueField for each series.
-
Change the label text of the valueAxis so that the negative values appear as positive. To implement this technique, use the customizeText function.
To further customize your bi-directional bar chart, implement tooltips and change the legend's alignment.
Feel free to share demo-related thoughts here.
