Hi,

I would like to make a volume visualization mixed with a heatmap kind off. I have 4 vector values: x coordinate, y coordinate, z coordinate and E the Value/ weigt of the coordinate.

I tried this code

    [x,y,z,v] = flow;
figure;
xslice = 5;
yslice = 0;
zslice = 0;
slice(x,y,z,v,xslice,yslice,zslice);
view(3);
axis([0 10 -4 4 -3 3]);
grid on;
colormap(flipud(jet(64)));
colorbar('vertical');
shading interp

From http://www.bu.edu/tech/support/research/training-consulting/online-tutorials/visualization-with-matlab/ However it didn't work because whatever I put in I get the same image out.

Can someone help me out with this? Thanks in advance!

The first line of that code loads some example data from MATLAB. I think that this is probably overwriting any data that you previously defined which is causing the plot to always look the same. Try removing this line:

[x,y,z,v] = flow;

and changing all the references to the variable "v" to refer to your variable "E".
