In 2013 and earlier I could do this to compare multi-line plots:
% make up some data
X1 = rand(5,3);
X2 = X1+rand(5,3)*0.1;
plot(X1); % draw dataset 1
hold on;
plot(X2,':'); % compare with corresponding dataset 2
hold off;
This is broken in matlab 2014: the second set of lines colours don't match up with the first set.
I guess this is because the axes keep track of the colororder index when hold is on.
How can I reset the colororder index so that subsequent plots restart with color 1, as in previous matlabs? I'd really rather not have to go through a for loop to draw each of the lines!

Thanks all for your help. For anyone who wants to do this in future:
I finally got the answer by email from Claudette at Mathworks Documentation.
set(gca,'ColorOrderIndex',1)
will reset the colour order, so subsequent plot calls will use the same colour set.
So:
% make up some data
X1 = rand(5,3);
X2 = X1+rand(5,3)*0.1;
plot(X1); % draw dataset 1
hold on;
set(gca,'ColorOrderIndex',1)
plot(X2,':'); % compare with corresponding dataset 2
hold off;
will produce comparable solid and dotted lines.

Starting with R2014b you have to explicitly specify a color, otherwise it will use the "next" color in subsequent calls to plot. For example:
plot(X1, 'b-', 'LineWidth', 3); % draw dataset 1
hold on;
plot(X2,'r:', 'MarkerSize', 10); % compare with corresponding dataset 2
grid on;
You might also find it interesting to run my attached colororder demo.

Still not understanding.
I have two sets of lines. Have you looked at the original code I posted? If you run my code in Matlab 2013, you will obtain the figure that Matz has posted below as a test. It shows two sets of lines, one for X1, one for X2, overlain, each in the same set of colours, but with different dash styles.
This is so that I can easily compare line set 1 with line set 2. I just want to be able to do this:
plot( X1 )
hold on
plot( X2 , ':' )
hold off
to where X1 and X2 are matrices, and that I can compare line 1 of X1, with line 1 of X2.
When I plot the second set of lines, it used to use the same colours as the first set. However, now since 2014b it does not! And I can't work out the easy way of achieving this seemingly common task.

I don't have R2013b installed anymore. Post screenshots.

That's odd. I'm using Matlab R2014a and it seems to be working fine. Are you using Matlab R2014b?

It was changed. Now plot uses different colors each time.

Ah yes it's R2014b ! Sorry.
