hi, yes, you can read by yourself the TEE file, but you may want to not depend too much of the Steema file format. This is just a workaround.

found a bug (?)
hi,
I did have a problem using the TAnnotationCallout.
you must reset
ChartTool1.Callout.Arrow.Visible := true;
in the form.OnCreate. If not the arrow is visible on design time, but not during the execution.
see you,
