hey guys, I have a problem with the plot instruction. Usually, when I type
figure
hold on
plot(x_1,y_1)
plot(x_2,y_2)
I will get a plot with two lines in different colors. I don't know what happend but it's not running with my Matlab version scince a few weeks. I'm using Matlab R2014a. When I type this code I get a plot with two lines and both lines are blue. I know that I can choose the colour in the plot enviroment with
plot(x_1,y_1,'r')
but I want that the color's chosen automatically.
Is there anyone who has an idea what I can do?

This is a difference that came in from R2014b onwards. The R2014a and earlier equivalent is
hold all

I can think of 2 ways to help you.
1.
plot(x_1,y_1,x_2,y_2);
Simplest way.
Or if you want some sort of controls over the color. You can download this function. Basically this function generate random distinguishable colors for you.
color_data = distinguishable_colors(2);
plot(x_1,y_1,color_data(1,:);
plot(x_2,y_2,color_data(2,:);
Or you can use to colormap function in MATLAB. It will do similar thing for you.
