How to plot two points simultaneously on image?

[intensity]

I want to plot two points simultaneously on an image. I tried using IMAQ overlay point and IMAQ Light meter for point. But when I try to plot two points using either of these two VIs, I find not even one point is plotted. How to resolve this?

If your image is zoomed out, the point size may be to small to allow a proper drawing of the point. Otherwise IMAQ overlay point works flawlessly...

Thanks for the reply. The program works fine. But as you said, the points are too small and hardly visible. How can we magnify them? Is there any method to show the points visible?

Why don't you draw bigger points ? You could use the IMAQ Overlay Oval to draw a circular point.

Hi, I tried plotting the two points seperately instead of array and it seems to work perfectly now.
