Hi There,

Can we add checkboxes to the chart legends? My requirement is to switch on/off the data series by clicking the check boxes.

Hi Sourabh,

Visifire doesn't allow adding checkboxes to the chart Legend. Instead you can create custom Legend with checkboxes and place it inside the chart.

My requirement is to switch on/off the data series by clicking the check boxes.

As you are trying to enable or disable DataSeries on click of corresponding legend entry, you can achieve this by attaching mouse event on legend. Inside the event handler you will get DataSeries and DataPoint as event argument which will help you to perform operation on the corresponding DataSeries or DataPoint. Please follow the code below.

void Legend_MouseLeftButtonUp(object sender, LegendMouseButtonEventArgs e)
{
   if (e.DataSeries == null)
       return;

   if (e.DataSeries.Opacity == 0)
       e.DataSeries.Opacity = 1;
   else
       e.DataSeries.Opacity = 0;
}
