Radchart - Item tool tip format help

[Yathish]

Hi,

Attached is the radchart i am working on. As of now when i point on the line series graph (the graph in orange color) - it displayes the y-axis value. For example it highlights 75 in the attached screen shot.

In my case, i need to just append a text to that value, say "marks=75". How to achieve this?

Can you please share your valuable inputs.

Thanks & Regards,
YK

Hi Yathish,

          You can modify tooltips in many ways.
First register this event for chart.

radChart.DefaultView.ChartArea.ItemToolTipOpening += new ItemToolTipEventHandler(ChartArea_ItemToolTipOpening);

then inside event put your formatting

void ChartArea_ItemToolTipOpening(ItemToolTip2D tooltip, ItemToolTipEventArgs e)
{
            string strMarks = "Marks : " + e.DataPoint.YValue.ToString();

            tooltip.Content = strMarks;
}

Hope it will help you.


Regards
Rahul
