Hi,

Thanks for the wonderful chart library. Your work is appreciated.

I want to know if it's possible to only display the circles on a line graph at data points where the value has changed or is about to change, or if the data point is a start or end point. The rest of the time I want the chart to behave as if there are points there, only no circles. Any help on how to accomplish this would be appreciated.

Thanks,
Sean

this requires you override a bunch of methods to do so. You have the code already. look into how the line chart renderer works
