scatter3 makes a 2D plot

I'm trying to plot the contents of a cell array (RSD_c{v}) composed of 5 32x3 double matrices. I used the following code:

figure;hold on;
cellfun( @(x) scatter3( x(:,3), x(:,4), x(:,5) ), RSD_c );
title('Relationship Between Relative Standard Deviation, Bootstrap Replicates, and Dimension')
xlabel('Bootstrap Replicates') % x-axis label
ylabel('Relative Standard Deviation') % y-axis label
zlabel('Dimensions') % z-axis label

When the graph is plotted, it makes a 2D chart. Tracing the points shows that they have x, y, and z coordinates. However, the graph is 2-dimensional, with the points color-coded by z-coordinate.

Does anybody know how to fix this?

You used hold before calling scatter3. When you turn hold on, it basically "freezes" the properties of the axes from being automatically modified (by functions like scatter3, for example.) If no axes exists when you call hold, it creates one in the default 2-D view.

You can create an axes with a 3-D view using the view command then hold it (or vice versa; hold prevents the properties from being automatically modified, but you can explicitly modify them.)

That fixes it. Thanks!
