Hi Alexei,
Thanks for using Syncfusion product.
The “text” properties of the points are used to customize
the labels. In remote data, we are
unable to specify the text to the Point collection, hence you can use “seriesRendering”
events to add the text properties to the point collection before the series
render. We have created a simple sample based on the query, please find the sample from the attachment
