Intensity Graph Scaling and Coordinate Transformation

[airguy1988]

Hello all. First post ever so plz bear with me. I am trying to plot data I am acquiring from a load cell in coordination with the X-Y position I am receiving from my motion control system. The load cell info is to be the z-axis. I am receiving the data from the motion control, then acquiring an average of the load cell signal and storing these to an array. I would like to plot this data for each movement of the x and y axis so that I can see a real time mapping of the data I have acquired. I have attached a program that calculates the x-y positioning required with the load cell data simulated by a random number. Plotting the x-y coordinates on the x-y graph is the standard measurement path I am going to be using. I would like the intensity graph to plot in the same fashion with the correct coordinates used on the axes. If I could over lay the xy graph and intensity graph, that would be a major bonus. I look forward to hearing any reply that helps me out on this one. Thanks in advance for your time and effort. I am just stumped on this one!

Sorry. Realized I did not include a SubVI. Removed that so the program should work if you download it direct. Just some notes: Spray height is in inches and normally is between 2 and 20 inches, Lateral spray angle in degrees normally falls in the 10-45 degree range. Transverse spray angle normally falls in the 2 to 10 degree range. Pin diameter is in inches and typically falls in the 0.020-0.080 range.

Sorry again. Not solved. Guess I shouldn't just press buttons not knowing what they do.

Hi Keith,

I'm not precisely sure what you mean by the following, but I'll take my best guess:

I'm guessing that you want to programmatically set the maximum values of the axes.  You can set this by using a property node.  Right-click on your internsity graph on the block diagram and select Create»Property Node»X Scale»Range»Maximum.You can then wire in the maximumvalue that you desire.  Thanks.
