Making a 3D plot from two cameras that are already collecting and plotting 2D data

[rbailis99]

Hello! I am having trouble creating a 3D plot of position in 3 directions (X,Y,Z). I am already able to plot the X,Z direction and the Y,Z direction on a 2D plot, but need help combining both sets of that data to make the XYZ plot. Right now I am able to plot the 2D graphs in real time, so it would be great if I could to 3D in real time too. See my attached labview screenshot. The attached code already works very well. Any help would be greatly appreciated!

Hi rbailis99,

3D plots in LabVIEW may not give you the speed you want if you're trying to view something in real-time. 3D plots tend to be pretty resource-intensive, so if you're planning on writing data rapidly/repeatedly to a 3D plot, you'll slow your code down quite a bit.

Warnings aside, the easiest way to create a 3D plot is to add a 3D Scatter control to your front panel, then pass your X, Y, and Z data into the Plot Helper.vi that is automatically created on your block diagram.

Hi! This was very helpful. Thanks for your advice. One question though. I would like the color of the plot to change with time or index, not the x coordinate as it currently does. Is there an easy way to make the scatter plot do this?

Hi! Have you taken a look at this article?
