Matlab update plot with multiple data lines/curves

I want to update a plot with multiple data lines/curves as fast as possible. I have seen some method for updating the plot like using:

h = plot(x,y);
set(h,'YDataSource','y')
set(h,'XDataSource','x')
refreshdata(h,'caller');

or

set(h,'XData',x,'YData',y);

For a single curve it works great, however I want to update not only one but multiple data curves. How can I do this?
