  Hi,
  We wanted to show the crosshair intersected all points y values with respective legend text.
  Since we wanted vertical line , so we used axisX crosshair but it gives only one value of x instead of all intersected points y values, if it is possible we can show those y values in their respective legend text.

  Kindly provide a soultion to show y values in lendend text from axis X crosshair
  Thanks

  Hi,
  Thank you for response,

  Since shared is made true, i get tool tip whenever mouse hovered on chart. I had created tooltip custom property for each datapoint, when tooltip shared was false. How to show tooltip of one datapoint info only when mouse hovered on datapoint.

  Since for above issue we need shared to be true , but also we need to show only one datapoints tootip.
  How to achieve this

  Thanks
