MATLAB: Plot different curves in cycle for

plotplotting

I want to plot 3 different curves in the same graph (one parameter changing).
if true
for M0=1.5:0.5:2.5
  disp('Valori scelti di Mi')
  Mi=0.4:0.05:0.7
[...]
  yyaxis left
  grid minor
  plot(Mi,Dad,'-^','LineWidth', 2,'MarkerSize',8);
  xlabel('Mi','FontSize',14)
  ylabel('Resistenza addizionale','FontSize',14)
  title('Resistenza addizionale presa Pitot subcritica','FontSize',16)
  yyaxis right
  plot(Mi,PhiD,'-*','LineWidth',2,'MarkerSize',8)
  ylabel('Coeff. di Portata','FontSize',14)
  hold on
(ignore the first line if true).
Wath I want is to get this graph with every blu and orange line with different style operating inside the for command.

Best Answer

You where almost correct. Just 2 small corrections:
1) "hold on" You added this line at the end of the script - this wont help you. Think about hold on as only between the two lines hold on / hold off that function is active (even if you dont specify hold off) -> just add hold on earlier in your code
2) use plotyy instead of plot. This allows you to get plots with 2 y axes
3) try to use handles, f.ex. h1 = plot(...). This allows you to accees the plotted lines much easier later in your script
