I want to be able to show a custom tooltip/hint when the mouse is over any of the bars on my Gantt series. How do I accomplish this using teechart 2014 standard?

Hello,
Since the Chart Tools are only included with the Pro version, you can't use the MarksTipTool.

Then, I'm afraid the only alternative I can think on is to use the series Clicked function to retrieve the ValueIndex under the mouse at the OnMouseMove event. Store this index, probably force a Chart repaint (Chart1.Draw) and use custom drawing functions at OnAfterDraw event when the index has been stored.
