How to highlight a region?

[AmitDeshpande]

Hello,
 
  I am trying to highlight a region. To explain my problem, I am attaching a picture file. I have a profile the main region (in this case its a circle), but it could be of a different shape like a standard efficiency curve or something. To illustrate, I selected a circle.
  Within this circle, based on the simulation, I would like the operating region using lines. These will be bordered by the circle. In both the pictures, point A1, B1, C1 and D1 or point A2, B2, C2 and D2 will be known. So, effectively it will be like drawing lines connecting these plots.
  The main profile (in this case the circle) could either be a picture on the VI or be actual data, depending upon which ever is simpler.
  Any inputs are highly appreciated.

Regards,

Amit

I now see the problem.  The Picture Functions are limited and will not support what you want to do.  I would suggest creating a VI to draw a series of lines to build the highlight region.  Not a pretty solution but it will work.  Disable Erase First to make it draw faster (See Daren's Nugget)

Hello Matthew,
 
  Thanks for the inputs. Infact this actually helped me a lot. I am not very regular user of LV and so don't understand what VIs are available and not. But I was able to get to DrawMultiple Lines VIs and that seems to be the solution for now! I haven't messed with it much, but was able to draw a closed region and draw these lines.
  Thanks though!

Regards,

Amit

Good to hear my example was good enough for you to find a solution.  Enjoy!
