Help getting 2D plot from 3d diffusion equation solution

mesh

Hi, I’m solving a point diffusion equation on a 3d boxmesh. The solution is u(t,x,y,z) and looks like this in paraview

but I want to be able to get a 2D plot where I fix say x, y and t and plot u(t_{fixed},x_{fixed},y_{fixed},z) on the vertical axis versus z on the horizontal axis. I have tried looking at slices in paraview but I want to be able to obtain a vector with these values in my python script. I should be able to access them like this?!

You can use PlotOverLine and Save Data to export the results as a csv file for instance.

Is it not possible to do this in my for loop when solving for different time values?

Solved this by storing values in loop for each time step

x_fixed_density = 10000
    for n in  np.linspace(x0,1,x_fixed_density):
     P_vals.append(u(n,1,1))
