Hello,
I have an issue with the 3D plots in LabVIEW. I tried to create a 3D Surface and a 3D Scatter plot.
For the 3D Scatter plot I connected 3 1D-Arrays but unfortunately there was no graph shown after the extraction of the data.
Also I am confused what needs to be connected for the z-axis of the 3D Surface plot since it requires a 2D-Array. What do I need to connect to it?
I attached a picture of the current data extraction in the attachments. Essentially the current program is performing a sweep, a frequency sweep with a varying voltage.
The problem is that none of the data which was extracted is reprensented in the 3D graph, the graph is blank.
Thanks and best regards

Hi Sunny,
you need to connect a 2D array of the data you want to plot to it. If you look at the graph from the top, you see an x-y- plot if you will. The Z Matrix tells the graph what z value a certain Point (x,y) has. There's an example for it as well, which demonstrates this fairly well.
As for your BD, I suggest getting rid of all the variables (why doe you use "step freq (Hz)" twice right next to each other? Also I would get rid of all the stacked sequences.
