回答： vik 2019-2-1

I am working with a 3D scatter plot that is mapping the X,Y, and Z positions of a certain body, the time spent at each point is represented by the the intensity of the color dictated by a colormap. My code works and the color bar also works, however there are few extreme values that skew the color bar thus reducing the usefulness of it.

How can I remove these extreme values from the colorbar yet plot them? I understand the sizes of the arrays should be the same, and I cannot remove the entries from my array as they are important to 3D scatter plot

scatter3(X , Y , Z ,15,time)

newmap = parula(100);

ncol = size(newmap,1);

zpos = 1 + floor(0);

newmap(zpos,:) = [1 0 0];

colormap(newmap);

h=colorbar;
