i need a help for making a 3 dimonsional graph

[Oliver2000]

Dear all..

i made a small program that can calculate the bandwidth of the magnitude in the fourier domain resulted from this mathematical formula: (V(t) = 1/(4*((pi)*t)**3/2) * exp(-(x**2+y**2 + z**2)/4*t) ) "Where x,y,z, have particular values".

Then i illustrated the relation between the bandwidth and the time in a 2 dimensional graph called in my program "New Results". This shows simply how the bandwidth changes when the time changes.

Now i am interested in a 3 dimensional graph, where the first 2 dimensions should be the values of x and y and the third dimension should be the bandwidth. (For z=1 and t is infinite).

How can i modify my program to do that?

Thanks in advance..

sorry i forgot to attach my program.. here it is..

Hi Oliver,

I did not see a 3d-graph anywhere in the code you posted!

So it looks like you want to know where to start. Please take a look at the postings I made to this thread where I posted example code and talked about all of the work invloved in producing the images.

After you have reviewed that code try to adapt that example for your use. If you get stuck...

1) Post back with what you have tried.

2) Exaplain clearly what Q's you have

3) Make sure your post includes data so those who try to help you can look at the same thing you are seeing.

Trying to help,

Ben
