How to Display Text in an Empty Bar of a Chart Series?

Description

This article explains how to render custom text in place of empty bars in a Bar or Column chart series.

Solution

A Bar or Column series can be used to visualize data as bars. An empty bar can be rendered by setting the data point’s y-value to zero and the series type to either Column or Bar.

To display text in place of an empty bar, you can use the [annotation](https://ej2.syncfusion.com/javascript/documentation/api/chart/chartAnnotation/) feature. Annotations allow you to overlay custom content at a specified position on the chart.

You can control the placement of the annotation using the x and y properties. Set the coordinateUnits to “Point” to align it with a specific data point. The content to be displayed can be defined using the content property.

Code Snippet

var chart = new ej.charts.Chart({
annotations: [
       {
           content: '<div id="annotation1" style="color:red;font-weight:bold"> E<br>M<br>P<br>T<br>Y</div>',
           x: 'Wheat', y: 20, coordinateUnits: 'Point'
       }, 
       //...
       ];
});
