How to change the text displayed in axis labels?

Platform: ASP.NET Web Forms |
Control: Chart

The text displayed in axis labels can be customized by using the client-side event OnClientAxesLabelRendering. Refer Chart Events for more information about the events available in Chart. Refer AxesLabelRendering Event for more information about the options available in the OnClientAxesLabelRendering event.

The Event Handler is provided with an object containing properties like cancel, data, model and type as parameter. The property data in Parameter object has options to customize the text of axis labels. The following code example adds “$” as prefix and “K” as suffix to the labels in the Vertical axis.


<ej:Chart ID="container" OnClientAxesLabelRendering="LabelsRendering" runat="server"> 
<script type="text/javascript">
    //Client-side event handler to handle labels rendering event
    function LabelsRendering(sender) {
        if (sender.data.axis.orientation == 'vertical')
            //Adding prefix and suffix to axis labels
            sender.data.label.Text = '$'+sender.data.label.Text+' K';


The following screenshot displays Chart with the prefix and suffix for the primary Y axis labels added in OnClientAxesLabelRendering event.
