Hi Niket,
ChartDirector charts are clickable. When you click on the data points or the line, a
ClickHotSpot (I assume you are writing a Windows Forms application) "HotSpotClick" event
will occur. In the event handler, you can write any code you like. For example, you can
write code to uncheck the checkbox. I assume you have already had the code that
removes the line from the chart when the checkbox is unchecked.
Hope this can help.

Hi Peter,
Thanks for the solution but i want something different. what i want is when i draw track
line in pause mode of chart, i displayed track line with dataset name and its value at the
point. is there any way at the end of the cursor label can we put some cross image to
enable users to delete that line from chart plot area. for example for one Y parameter say
engineOilPressure:100 (X). when user move the mouse over chart plot area entire cursor
label display like above but when user press (X) that plotted line will disappear. Can you
suggest me some way to do this.
Thanks for your valuable time.
Regards

Hi Niket,
The track cursor label is drawn by your code, so your code knows the positions of the
labels. Your code can therefore put normal button controls (or other .NET controls) after
the labels. When the button is pressed, in the button click event handler, you can hide the
line.
Hope this can help.
