    We are looking at replacing HighCharts and are using Telerik components in other areas.

    Due to the volume of data we only give HighCharts a subset of it. For instane if there are 50,000 points we provide an average of 1000.

    When zooming is applied we get sever server side call to provide 1000 zoomed in points.

    I am trying to implement this in RadHTMLCharts but struggling to an event to hook into Serverside.

    All I have found is client side

    As the number of charts per page is dynamic I doing this all in Code Behind using a custom DataTable (no mark up)

    Hi Rick,

    A possible way to achieve the described by you scenario is to utilize the RadHtmlChart's Data navigation functionality.

    You can also test this feature in our online demos here:

    Hi Rick,

    Yes, unfortunately the suggested functionality is supported only for stock layoyt charts and currently is not available for ScatterLineSeries. There is an existing feature request for separating the navigation functionality in order to be applicable for each series type, so you can track it and vote for it here:

    Meanwhile, you can take a look at the zooming functionality, allowing you to zoom only a specific selection of the chart:
