Thread Subject: Plot several vertical lines in different colors

Hi,

I want to plot vertical lines, given the matrix interv_plot (see code below), where the lines are endpoints of an interval. E.g. interv_plot(j,1,k) is the left point of the k-th interval at level j, while interv_plot(j,2,k) is the right endpoint.

Now I found in the web how to generate vertical lines in a plot (don't know if this is optimal), generating imaginary numbers.

What I'd like to have is to autamtically get assigned a different color to every level j, since J also varies, while the different intervals on the same level have the same color.

Any ideas on this?

Thanks

Thomas


for j=1:J
    for k=1:K
        p1 = interv_plot(j,1,k); p2 = interv_plot(j,2,k);
        h1 = p1 + t*i; h2 = p2 + t*i;
        plot(h1, 'm-.', 'Linewidth', 1); plot(h2, 'm-.', 'Linewidth', 1);
    end
end

thomas, try this...it works

%interpolate to get J colors
cols = get(0,'defaultaxescolororder');
cols = cols(mod(0:J-1,length(cols))+1,:)


for j=1:J
    for k=1:K
        p1 = interv_plot(j,1,k); p2 = interv_plot(j,2,k);
        h1 = p1 + t*i; h2 = p2 + t*i;
        plot(h1, 'm-.', 'Linewidth', 1, 'color',[cols(j,:)]); plot(h2, 'm-.', 'Linewidth', 1,'color',[cols(j,:)]);
    end
end
