Load-pull Power contours

[thoalfukar]

I was trying to implement a code to plot the Load-pull power contours which can show me the maximum output power and the other 3dB power contours but it seems I gave up. 

Is there any of you could help me please with this problem. I wish if there is a ready code for that. the one which is already in the Labview is very slow and doesn't shows me the contours that I want. 

Thank you in advance for your attension

The Max height is a point take 0.5 off the Max

sorry, what do you mean exactly, I did not get you exactly

I saw your block diagram note.  Not that you saved any data in the controls as default values but, If the max value is a single point and you want a contour line .... Well, a line segment just can't be drawn with only 1 point can it?
