drag marks or automatic positions?

Post by fjrohlf » Fri Dec 11, 2015 4:18 pm

Is there a function that will help prevent overlap of marks for a pointseries? I see some likely sounding options but I have not been able to see any difference that they make. I am also having a problem enabling the dragging of marks. The demo works but not in my code even though I believe I have copied all the necessary elements. There must be some trick. Are there more examples or more extensive tutorials or explanations of how to position marks or enabling dragging?

Thanks

Hello,

You can find examples of both using the TDragMarksTool and algorithms to custom position the marks here in these forums. Ie:
- Adding a TDragMarksTool to a TBarSeries here.
- Custom positioning the marks in a TBarSeries here.

Both examples use a TBarSeries instead of a TPointSeries, but it should be the same.
