MATLAB: Hiding legend in plot

legendMATLABplot

Dear All,

I want to hide one legend from my graph. Could you please suggest a procedure or steps to do it.

Here is the code below to hiding my legend but doesn't work.

legend(h4,'off')
legend(h4,'toggle')
legend('h1','h2', 'h3', 'h4','h5');

Many Thanks in advance

Babai

I assume you have 5 handles, h1 through h5, but want to hide h4 from appearing in a legend. If that's the case, since you know all handles, the easiest way is probably

legend([h1 h2 h3 h5],{'h1','h2','h3','h5})

Try this:

h1 = plot([], 'DisplayName','want to withdraw this if line unexist');      % Blue line
hold on;
h2 = plot(rand(1,10),'r', 'DisplayName','hello');  % Red line
h3 = plot(rand(1,10),'g', 'DisplayName','world');  % Green line
legend('show')

See the legend documentation for Remove Legend Border.

See if this does what you want:

[hLeg,hObj]=legend([plot2 plot1 plot3 plot4 ],{'experimental data d=3.5','Model 1: d=3.5','Model 2: d=3.5','Model 3: d=3.5'}) 
set(legend,'Location','NorthWest')
set(legend,'FontSize',12)
axis([5,15,6,7.8])
set(gca,'fontsize',12)
xlabel('Wall thickness [mm]') % x-axis label
ylabel('ln(F_{max,k}) [-]') % y-axis label
legend('boxoff')                                        % <= Change This Line

I can’t run your code, but that should work (in R2016a). If you have a different version, the command to turn the legend box off may be different.
