Thread Subject: how to change the color of figure using command

Already got a figure fig01.fig containing 2 curves generated from someone else' code below.
a=[1:100];
b=[2:101];
plot(a);
hold on;
plot(b);

Notice I already got the above figure, how can I change the color and line style of curve 1 using command? thanks.

Arthur,

Give this a shot (after opening the .fig file):

h=findobj(gca,'type','line');
set(h(1),'color','r')

If the figure is as simple as you state, you can also use the following:

h=get(gca,'children');
set(h(1),'color','r')
