I've noticed that openGL and non-openGL charts have different types of text (labels, titles, annotations) behaviour while chart rotation and elevation. OpenGL text looks like glued to the chart and rotates/elevates with it. Text in non-openGL charts is always parallel to screen so it is easy to read it from all charts positions. I have to use openGL charts but I don't want text to rotate. Moreover I need chart title to stay at the same place while rotating like independent header(but at the same time I need to print it with chart - maybe I can use ordinary Windows Forms labels and then include them into printing sheet somehow?). Is it possible?

Thank you.

Hi bairog,

I could reproduce the issue here. Header, sub-header, footer and sub-footer shouldn't rotate, they should stay parallel to the viewer's plane. I've added this defect (TF02011598) to our defect list to be fixed for future releases.

WinForm labels can not be used as for printing they should be drawn on TeeChart's canvas and once it's drawn in the canvas they will start to rotate.

To my mind openGL chart titles and labels should behave like non-openGL (while rotating/elevating titles should stay at the SAME PLACE and parrallel to viewer's plane, labels should stay parrallel to viewer's plane and ELEVATE/ROTATE with chart). Did you mean the same or maybe you have some other arguments?

Hi bairog,

Yes, you are right. We have added the problem to our bug-tracking software and a fix to it will be considered for inclusion into the next release.
