@Cris LaPierre Thank you! How can I label x, y, z axis in bar3? I need to change y axis values from (0 to 50 ) to (-25 to 25) and need to label as z

Labels are done using xlabel, ylabel, and zlabel,
Tick labels are similar: xticklabels, yticklabels, and zticklabels
Change the tick locations using: xticks, yticks, and zticks.

This version assigns a solid color for each bar, based on bar height.
z = randg(1,5,3);
h = bar3(z);
for i = 1:numel(h)
h(i).CData = repelem(z(:,i),6,4);
