Plot 3D figure from a pcolor figure

Hello,

I have generated a figure by using "pcolor" to see the propagation of laser into plasma (as shown in below figure). The laser is specified by color such as read, blue,... The green color shows the plasma

But the case is I want to plot a 3D figure from this "pcolor" figure to see the real behaviour of laser inside plasma .

Therefore, I wonder is there anyone having any idea on that?

Thank you very much.

Hi,

This is totally dependent on the data you want to visualize. For 3D visualization of your data, functions like surf is very handy. You can also use https://www.mathworks.com/matlabcentral/fileexchange/37268-3d-volume-visualization , which provides an interactive 3D volume visualization.

Hope this helps!

Thank you for your reply.

When using "surf", the requirement is the data of x, y and z axis. But actually from "pcolor", there are no output data created.

So maybe I need to find another approach. Do you have any idea?

can you give more details about what you mean by "I want to plot a 3D figure from this "pcolor" figure to see the real behaviour of laser inside plasma".

If you just want to shift the pcolor in the 3rd dimension for better visulization. This can be achieved by changing the ZData surface property of the pcolor like

plt = pcolor('youdata');

plt.ZData = 'yourvalue';

for other Surface properties you can refer to the link

Wow. Let me try.

Thank you. Can I still ask you if I met any problems?
