3D surface layer plotting

[estomax]

Hi All,

I got help from you guys a couple of weeks ago about making a 3D array, and that was a success, but now i am at another stumbling stone. i am trying to take that array (x, y, z coordinates) and plot the x and y coordinates on a plane with the z plane taking a 4th variable (a measurement, not the z coordinate, there will be a plane for each z axis coordinate). the 3D surface tool however puzzles me, it wants into the x and y field a vector and into the z field a two-dimensional array. Can i plot a surface (in real time) by taking in measurements and assigning them to a precalculated x/y grid? I am not sure on how to go about doing that, so if you guys have input/tips/hints, that would be great!

thanks!

ok, so i figured out how i want it to happen. here is a basic vi that i built to test it. Now my problem with this one is that the first time i ran it, it built me a mesh, but after closing it and opening it again it just plots points? I can't figure it out for the life of me.

see the attachment rand3DplotTest.vi for that.

Now my second dilemma is, i am not getting the 3D graphing functionality in my main vi that I am trying to build. When i build it, it calculates the array, and starts taking measurements. The problem that I am running into is that as I send in the updated vectors (like i would in the rand3DplotTest.vi, except real numbers this time), the 3D graph stays blank! see arrayTestAndMeasure3D.vi for that. I even tried copying and pasting the rand3DplotTest into the main vi at the same place and it still didnt work... Only thing that I can think of is I have too much stuff in one .vi?

I think labview doesnt like me being in school on a sunday...

cheers for any help!

PS. i am using LabView 7.1

Not sure why the plot style changed.

You can progamatically set all of the properties.

See this thread for an example were I show how to work with many properties using multiple plot various plot styles.

Hey Ben,

thanks for the reply, there is a lot of information in that thread but i'm not sure if it quite solves the issue i'm having. Is it necessary to add a whole lot of variables like you are adding to solve this issue ? (i dont care for transparency and color map honestly)

thanks and bump,

Marko

No just pick the parts you want and use those. That was a "worse case" example.
