Reset the Color Order Property of an axis

I saw this question on the Expert's Exchange and I want to know the answer without paying for it.

I was wondering does anyone know how to reset the color order and line style manually in matlab?
I know each time you call high-level functions like 'plot' and 'plot3' it resets them automatically (provided you didn't do a 'hold on' beforehand) but how do you do this manually?
I'm NOT trying to set a new color order or line style, I just want to reset them so that my next call to 'plot' starts at the beginning of the current color order and line style lists again and continues.

Thanks in advance.

Yes, Expert's Exchange is a pile of shite.
Here's one way you can do this:

%store the originals
origCO=get(gcf,'DefaultAxesColorOrder');
origSO=get(gcf,'DefaultAxesLineStyleOrder');

%set them to something else:
set(gcf,'DefaultAxesColorOrder',[1 1 0;0 1 1;1 0 1],...
'DefaultAxesLineStyleOrder',':|-|--')

%back to default
set(gcf,'DefaultAxesColorOrder',origCO,...
'DefaultAxesLineStyleOrder','origSO)

%You can also set them on a global level. Try:
get(0,'DefaultAxesColorOrder')

This doesn't seem to be working for me.

This loop plots the test data that is selected by the user. There may be any number of plots to be compared on the same axis:

% code
hold all;
            for j=1:length(testrow)
                plot(xaxis{j,:}',testdata{testrow(j),:}','LineWidth',lw)
            end

%/end code

testrow is a vector containing the selected rows from a list box.

Does the hold all; command make it so that the solution in the previous post does not work? Every time my plot button is pressed, the colors start off with the next in line and not with the regular blue.

I suspect so --

I'd first try to reset the default order in the loop and see if it
starts over again; I'm thinking even that may not.

If not, you would probably have to keep up w/ the number of plots and
rearrange the order to make the position of the first default color that
position in the color vector.

AFAIK there's no property user-settable that lets you only reset the
internal index into the order array for color (or linestyle either, for
that matter).

Seems like another of the "so obvious but..." kinda' missing
details....I've noticed it before; unlike some others that come up from
time to time I don't recall this is one I ever formally submitted a
feature request for.

I had thought of keeping track of the order like you mentioned. The more I think about it, it might not be to difficult. Thanks to all for helping.

Oh, I agree that it's not particularly hard at all; just one of those
pita details that seems as if shouldn't be necessary is all...
