3D plot - select coordinates

[ClaudiaRamos]

Hello,

I would like to know if there is a way to know the coordinates on a 3D surface plot in LabVIEW. Actually I know one way but I would like to know if there is another. The way I know is: right click on the 3D plot and then click on ´Properties of 3D plot´. Then click on ´Cursor´ and finally set the X, Y and Z positions to the desired point on the plot. I have attached a few images showing this. I have also in the Blockdiagramm a PropertyNode that shows the selected coordinates.

OK. Now, my question is...Is there a way to select a point just clicking on the graphic?? (without right clicking and selecting ´Properties´ and so on).

Thank you very much in advance,

Claudia

Hello ClaudiaRamos,

I did some research and wrote a small VI to test these cursor things.

Unfortunately, I just could do it like you. I am afraid, it is not possible to click in the 3D diagram and have the x, y and z value output.

(Come to think about it: how should the computer know where you click? The mouse is not a 3D input device and there can be more than one point in the 3D room you could "mean" with your click - which one should the computer take?)

Also, I have a question: should the point you select be on the surface of you graph, or anywhere in the diagram?

I think the way we are trying just selects any point, regardless if it is on the surface of the plot, or not.

I am sorry I cannot give you a solution at this point now.

Best regards!
