Tooltip only for provided data points

Hi,

First of all, great Charting component. Just started using it.....

The question from me is, I would like to have a tool tip in a 2D line graph with only provided data points from me. As of now, it displays even the data points I havent provided and solves itself for the intermediate points. Is it possible someway to display the last or nearest "provided" data point in the tool tip?

Thanks in advance

Best,
Bala
