Help with multiple plot at same figure

Hello, I've got a problem. I don't know how can I do a multiple plot at same figure, this is my code,that I wanna merge

for j = 1:Ne
        jj = jj+1;  if jj > Ne, jj = 1; end
        plot(up(:,j),zp, scm(jj,:),'LineWidth',2,'MarkerSize',3); hold on 
        st(j,:) = sprintf('%5.1f ut',t(j));
      end

      for j=1:nl
          plot(zp,lp(1,j),'k*','LineWidth',3,'MarkerSize',2); hold on
      end

hold on

[Marco Esteves]

I've got two "hold on".

The first hold on to hold the lines from the first plot instruction and the second hold to hold the line from the second plot instruction.

With this code, the second "for cycle" doesn't appear on figure.

Please don't accept an answer that's not what you are looking for!

Your way to use the hold on isn't optimal, first create the axes object with the axes function if you don't have one already, now just do hold on once before your for loop.

I don't know exactly what you are looking for when you say "Help with multiple plot at same figure", do you want to plot everything in the same axes or in two different axes in the same figure?

See the subplot function if you want two axes (one for each loop).

that'll teach me for not reading the question fully...

I agree that the actual problem is not that clear

[Paulo Silva]

The questions are almost never that simple :) and many times the OP will change his/her mind and ask something very different from the first question.

Answer 2

[Marco Esteves]

I've got 2 cyles to get plot curves. I need to override the result of plots in the same figure

      for j = 1:Ne
        jj = jj+1;  if jj > Ne, jj = 1; end
        plot(up(:,j),zp, scm(jj,:),'LineWidth',2,'MarkerSize',3); hold on 
        st(j,:) = sprintf('%5.1f ut',t(j));
      end

      for j=1:nl
          plot(zp,lp(1,j),'k*','LineWidth',3,'MarkerSize',2); hold on
      end

to be honesdt thats still not really clear what your trying to do.

Anyway - try cla to clear the axis or hold off (then on agian after the 1st plot command).
