TMarkToolTip text showing only one time

[Gary]

I have an issue where I only see the TMarkToolTip text showing only one time when I hover over it unless I click the series or hover over another one and then back. I'm using build 2023.39 and Delphi 12.

Hello,

The TMarksTipTool has a HideDelay you can use to control the milliseconds to wait until the mark is automatically hidden.
If you don't want it to be automatically hidden, you can set it to -1. This way it will only be hidden once the mouse cursor leaves the point.
Is this what you would like to achieve?
