I am trying to plot a LG beam equation in python where Electric field depends on r (transverse distance from propagation axis), theta (rotation Parameter), and z (propagation distance) and then electric field is calculated

I have made r = np.linspace(0,10,100) theta = np.linspace(0,np.pi,100) z as np.linspace(0,80,100)

then E = function of (r,z,theta)

The issue is I am trying to plot E but not successfull in plotting values of E as scatter or surface but not getting it as expected.

What i want to do is to plot values of E with respect to three axis r , z and theta

Can anyone please guide me how to achieve this using python or any other software

  • It should work something like this where field rotates like in the attached link mathematica.stackexchange.com/questions/202641/… Commented Nov 5, 2022 at 8:34

    Please provide enough code so others can better understand or reproduce the problem. Commented Nov 5, 2022 at 8:45
  • @DinkarMishra are you interested in the 3-D surface plots with spiral folding at the end of you link you mentioned, or in solid volume plots? For complex 3-D surface plots, I think you need something like this: matplotlib.org/stable/gallery/mplot3d/… . If you provide the code with the input arrays, we can help you to get the plot system working. Commented Nov 5, 2022 at 8:59
  • Aso by the way, r = np.linspace(0,10,100); theta = np.linspace(0,np.pi,100); z = np.linspace(0,80,100) are only 1-D arrays, so the resulting plot will be a flat 3-D line. You need to use np.meshgrid or array broadcasting to make grids: numpy.org/doc/stable/user/basics.broadcasting.html Commented Nov 5, 2022 at 9:02
  • Actually the function is something like E = xyz and all x y and z are variables of different values If i can show x y and z on all three axes then where should i plot E which depends upon all x y and z. this is the main issue. I tried all the above mentioned cases but my aim is to show variation of E with respect to x y and z Commented Nov 5, 2022 at 9:11
