Query on tooltips and AfterDraw event

Hi,

Can tooltips be displayed over text displayed using the AfterDraw event?

My requirement is this: I have to display some text on the chart that I have plotted. For this, I am using the AfterDraw event to dynamically display my text. So far I'm ok.

The question that I have now is whether I can display some tooltip as the mouse moves over the text that I have displayed ? I have displayed some formula as my text and as the mouse moves over the formula, I want to be able to expand the variables and give some description in a tooltip.

Does TChart have any feature which can support this ?

Thanks in advance,
spacemanspiff

Hi spacemanspiff,

Have you thought about using Annotation tools for that? You'll find examples and information on how to use them at the features demo (All Features\Welcome !\Tools\Annotation), TeeChart Tutorials (Tutorial 18 - The TeeChart Tool Collection) and Maps demo. All those items are available at the TeeChart program group.
