Thanks for using Syncfusion product
It is not possible to set the text and interior for a point in the datasource directly, but you can make use of the “preRender” event in the chart to assign text and interior for each point.
For your convenience we have created sample based on the query and your json data (graphTotalData) is referred in the “jsondatachart.js”. Please find the sample from the attachment
Thanks for your update, kindly let us know if you need any further assistance on this.
