Okay,

I'm plotting data in a GUI on an AXES which is on a PANEL.
1) I plot the data to the axes handle (This works fine)
2) generate a new axes to overlay on top of the first axes and plot some more data

When generating the second axes, I *think* i set the COLORORDER property for it by writing:
set(data_axes(2), 'ColorOrder', rand(length(DataSet),3))

In the next line of code, I plot the data to the axes, but the color reverts back to the default ColorOrder (red, then green, then blue, ...).

What gives? Do I need to specify before or after the plot command or should that even matter? (i've tried both)

High-level plotting functions reset many axes properties to their defaults.
See "Setting Default Property Values" in the MATLAB documentation.

Basically, you want to do something like this:

set(get(data_axes(2),'Parent'),'DefaultAxesColorOrder',rand(length(DataSet),3))

That is, define a default value for the axes ColorOrder property on the
parent (UIPanel) level.

Or, you could use the line function to plot data:

set(data_axes(2), 'ColorOrder', rand(length(DataSet),3))
line(x,y,z)

% YOU NEED "HOLD ALL"

figure;
h(1)=subplot(1,2,1);
plot(rand(5));

h(2)=subplot(1,2,2);
set(h(2), 'ColorOrder', repmat([1 0 0; 0 1 0],3,1));
hold all;
plot(rand(5));

pause(1);

set(h(2),'Position',get(h(1),'Position'),'Color','none');

Plot will reset the ColorOrder property by default.
Yet another way to deal with that:
Set the NextPlot property of the axes to replacechildren that will prevent higher level plot from resetting all the properties.
set(data_axes(2),'NextPlot','replacechildren')
