I have a plot that uses the slice command.

Is there a way to rescale the colormap of the resulting slice as would usully be done throiugh caxis([lower upper])?

在 MATLAB Online 中打开

caxis() also works for slice(). See the difference between two figures

[X,Y,Z] = meshgrid(-2:.2:2);
V = X.*exp(-X.^2-Y.^2-Z.^2);
xslice = [-1.2,0.8,2];   
yslice = [];
zslice = 0;
figure()
slice(X,Y,Z,V,xslice,yslice,zslice)
figure()
slice(X,Y,Z,V,xslice,yslice,zslice)
caxis([-2 2])

Ahh great, thank you, you confirmed my suspicion!

I was encounering an error message when trying to do this, hence my question. My plot is a combination of several isosurfaces and a background slice. I think the error was due to Matlab believing I was enforcing the colorbar onto the iso-surface part of my plot, as opposed to the slice. By simply plotting the slice first, it was fixed.

Thank you, sir!
