Hello Steema-Experts!!
I use a Tee-Chart where the x-axis is my timeline. In some situations I want to set trackmarks on the x-axis. These trackmarks should be little symbols which I have created before (some little gifs or something else).
When I click on one of these symbols than the chart should be show the values beginning at the moment where the symbol was set.
It would be nice when I can delete a symbol when I pull the symbol outside of the chart.
Have anyone an idea how I can realize this??
Happy for any help!!
Bye Thomas

Hi Thomas,
one way will be to draw your own symbols to the Chart Canvas following the techniques outlined in "Tutorial 13 - Custom drawing on the Chart Panel". But will be a little complicate when you've to remove them.
Another technique would be to use the TRectangleTool to draw the symbols, setting an image into the tool. This will allow you to add and remove them easily.
