hello again, i have this files that i extracted from my hydrodynamic simulation on delft3d, but i need to actually see them as a whole, since i already extracted the particular data i needed.

X 1x71x42x6 143136 double
Y 1x71x42x6 143136 double
Zp1 2500x71x42x6 357840000 double

jd_p2 2500x1 20000 double
jd_p3 2500x1 20000 double
jd_p4 1284x1 10272 double
so how can i plot ?
any ideas, i am a newbie and i dont know coding, so please something detailed :) thanks

For any one timestep, how would you like to see the 71 x 42 matrix of 6 layers visualized?
For example is layer N "on top" of layer (N-1) and there are NaN values for each location where the layer below should show through?

yes, the layers are from vertical depth, 1 is at the surface and 6 is at the bottom.
and yes, there are NaN values, since not all of the 71x42 dimentions have values, because it is the surface of an estuary.
and like this one, since i have to show how well mixed it is.
any help, please ;)

Use slice() to display in the form of the plot you have posted.
