Developing radar PPI display in Labwindows/CVI

[ASIM_BHATTI]

Hi all

I need to develop radar PPI like display in Labwindows/CVI. I have developed rectangular display using 'PlotIntensity' function but do not know how to convert it into circular display like PPI (like in sonar/radar)?

Kindly help me.

Regards

Asim

Hi,

I think you need to program the canvas control.

You can programmatically draw lines, pixels or arcs of desired color and distance from a center point.

That may be enough to simulate the radar display.

Well, the screen is always going to be rectangular. But you can have the parts of your plot out of the circle drawn in VAL_TRANSPARENT. I'm actually not entirely sure whether transparency is allowed on density plots.
