Thanks, that was enough of a pointer to get me started. im creating custom balloon tooltips at the x/y cursor location now.

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?

thanks. that worked and actually solved my mark problem anyway.

Thanks, that works great. However, there is a margin around the two bars which I don't want. how do I get rid of that, or keep it a fixed size? it presently resizes the same as the bars.

Also, how can I stop my mark text in each bar from being pushed upwards when the bar is resized smaller?

I have a gantt chart with 1 series. this series uses 2 y positions (0 and 1) to create 2 bars. I want the bars to always be directly underneath each other with no spacing and I want the 2 bars to fill the chart and scale appropriately when the chart is resized. how do I accomplish this?
