3d curve

[hakan_s]

hallo, i have a simple question.

i want to draw 3DCurve, which plots Sinuswave(y-axe), time(x-axe), and position(z-axe).

i have a simple example, that i didn't succeed.

can anybody help me?

Thanks

Hi, try this.

I hope it will answer to your question.

Bye

Sorry I am trying to attach the file with no success....

thanks for your reply

but that's not what i'm trying to do.

first of all it must be continuerly becaus i want to plot one of output,

second the time axes must be shown.

for example : 3D is time-output-position.

in my VI i cannot see the Curve. that's my question. Why? i see onyl a point..

thanks...

You see only one point because you only generate one point. Creating an array from a scalar just makes an array of lenght=one.

You could built your arrays in shift registers (But make sure the array does not grow forever or you'll run into memory issues).

Attached is a very simple demo that builds three arrays. (1) i=time, sin(f(i)), position (from a control) and plots it in 3D. See if this can point you in the right direction.

thank you very much,

wenn i want to plot two sinus curve with different positions or more than two, must i use 3D parametric surface?

is it right?

thanks
