problem with 3D graph

[vispacespace123]

Hi 

I am trying to use 3D graph but I have a problem with dimensions, could you help me to find a solution.

the VI is attached bellow.

You're wiring an array of errors to a 2D matrix input...

There's a function for creating a ramp pattern... It's call "Ramp Pattern.vi"

yeah sorry  I did a mistake , I wanted to wire it to the gate voltage Vg.

I correct it here but  i got the same problem.

[wiebe@CARYA]

That value you're wiring to X Matrix is a scalar, while the Y values is an array.

As a result, the X values become a 1D array, while the Y values become a 2D array.

You should initialize an array with the length of the Y array in the for loop, and the value of X. That way you'll build a 2D array of X values, where each column has the same value.

okay I did it but how can i do this (You should initialize an array  with the length of the Y array in the for loop, and the value of X)

Wire an Array Size to the Y values. Wire the result to the Initialize Array.

Almost there.

I Added an array size to Y then i wire it to the initialize array X . am I correct?

Well, I'd stick to left-to-right programming, but that was what I mend.

i think it works thank you ,now I trying to export the results from this graph to excel but i could not.

As that is a different topic, I'd post details in a new thread.
