The rectangle tool is great. Is there a way of drawing a similar shape with more than 4 sides? I need to be able to draw an "n" sided shape and know if a given point in the colorgridseries is inside the shape or outside.

Thnks in advance.

Hi dpatch,

You could try using Chart1.Canvas.Cube method.

Thank you for your response.

I guess I was not clear about what I was asking. I need to draw a shape, say a hexagon or an octogon...using something similar to the rectangle tool. Maybe I could give 6 points as the shape bounds and it would connect the points, drawing a 6 sided shape.

My application needs to draw bounds (or an outline) around a feature in an image then manipulate the point values inside the shape. What you have done with the rectangle tool is perfect, if I could only add more than 4 sides.

thanks again in advance.

Hi dpatch,

Thanks for the information.

I'll add your request to our wish-list to be considered for inclusion in future releases. In the meantime, the only way to achieve that I can think of, is using existing TeeChart's Canvas methods for drawing 3D polygons combined with text output methods like TextOut or TextOut3D.

OK, thanks for the consideration. Remember, I am looking fo a 2D shape, not a 3D shape.

In the mean time, I am going to look at the source code for the rectangle tool to see if it can be easily modified.

Thanks again!

Hi dpatch,

Ok, in that case you may be also interested in the polygon drawing methods included in TeeChart's Canvas.
