MATLAB: Slice plot gives black surfaces

Question

hey,

im having trouble with the slice plots.

i have a 3D matrix of electric field which i want to plot in the x-y plans along the z axis. (the third dimension of the matrix is the field in different Z axis values)

x,y,z are with dimensions of 1X201, Eg are with dimensions of 201X201X201

This is my code:

figure

xslice = [];

yslice = [];

zslice = [z(1),z(50),z(70),z(201)];

slice(z,y,x,abs(Eg(:,:,:)),zslice,yslice,xslice)

colorbar

the result i get is black surfaces, (i need to see the field distribution in x-y plane in each surface).

what can be the problem? how can i fix this?

This is the result:

thanks

Answer 1

Planes are not black. THe mesh is just too fine

Add to your code

h = slice(z,y,x,abs(Eg(:,:,:)),zslice,yslice,xslice);
set(h,'EdgeColor','none');
