How to render a blank bar and average line in React Column Charts?

Description

This article shows how to render a blank bar and average line in React Column Charts.

Solution

To render blank bars in React Column charts, you can set the color property to transparent in the dataSource of the chart. Then, map that property to the pointColorMapping property in the series of the chart.

To render an average vertical line, you can set the stripline for the y-axis by specifying the start and end properties in the stripLines of the axis.

Code Snippet

  primaryYAxis={{
           labelFormat: '{value}%',
           edgeLabelPlacement: 'Shift',
           majorTickLines: { width: 0 },
           lineStyle: { width: 0 },
           stripLines: [
               {
                 start: 1,
                 size: 3, sizeType: 'Pixel', dashArray: "10,5", visible: true,
                 color: '#69924e',
                
               },
             ],
       }}
