Intensity Graph

[rolltide25]

Hi All,

Can you help me plot the x position on the x-axis, the y axis position on the y axis, and the current data as the intensity on the intensity graph?  I attached the part of the VI where I am trying to do this.

Thanks

No, you only attached an image. That is pretty useless.

You need to initialize a 2D array of sufficient size and keep it in a shift register, then map xy position to indices and use replace array subset to place the data.

I attached the VI that I have been playing around with.  I cannot get the data onto the intensity graph.  I need the x position points on the x-axis and the y-points on the y-axis and current as the intensity.

Thanks

Whatever you are doing makes no sense whatsoever. I would recommend to start with a few simple tutorials.

Attached is a very simple example showing what I had in mind. You need a fixed size 2D array in memory (in a shift regsiter so it remembers it's contents across iterations) and replace elements based on x, y, z.

(... If you only want to show the latest point, remove the shift register. However, in that case an xy graph would be better)
