    Hi,

    I have read Performace tips for RadChart Control and i wan to know  how to remove item label and a point mark visual.

    Reference of telerik Document.

    Simplify the chart item ControlTemplate - e.g. the Line item template contains by default an item label and a point mark visual. The point mark visual can be removed (as they are relatively insignificant when rendering thousands of records). With lots of points the sheer number of UI elements simply bogs the system down as discussed above). So if you cannot reduce the data points, you will need to simplify the chart item ControlTemplate.

    Note that simply changing their Visibility will not do the trick, they should be physically removed from the template.
    Can you please advice me on this as i am having lot of data in my radChart and i have set Visible property of Label and point mark but as per the document if we want to gain performance improvement we need to remove this element.

    Thanks

    Hi pratik,

    One possible option in this case would be to retemplate the element of interest. Additional information on this is available in the following topic:

    I hope this gets you started properly.

    Hi pratik mehta,

    Attached to this message, is a small application which replaces the pointmark with a textblock. You can remove this as well from the template, to have no control for a pointmark.
    I hope this gets you started properly.

    Sincerely yours,
