Hi,
Before asking my question, I must admit that I did not put much effort to understand the concept of plotting data at desired location (radiusValue, azimuthValue) on QwtPolarPlot from the examples and source code.
My requirement is to divide the plot area into 3 equal circular regions as shown in the attached figure circular-regions.png (region1 - with radius R1, region2 with radius R2 and region3 with radius R3. Radius of the plot = R1 + R2 + R3 and R1=R2=R3) and plot points, lines and custom shapes within those regions.

Please suggest the easiest way of drawing points, lines on QwtPolarPlot.

Thanks in advance.

swamy.
