How to change the text displayed in axis labels in JS Chart ?

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

JS

<div id="container"></div>
<script type="text/javascript"> 
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';
}
$(function () {
    $("#container").ejChart({
        axesLabelRendering: 'LabelsRendering',
    });
});
</script>
