How I can change the legend of a graph from vertical to horizontal

hay, I want to present a graph with a horizontal legend. And my program in Matlab it gives a graphical presentation with Legend vertical is what I can change it and how.. ?? I would like to have a horizontal legend below the X axis

program:

figure(9);

plot(x,TFVP1S,'-k','linewidth',1.5)

hold on

plot(x,TSVP1S,'--k','linewidth',1.5)

plot(x,TFMSLTS,'-r','linewidth',1.5)

plot(x,TSMSLTS,'--r','linewidth',1.5)

plot(x,TFAS,'-m','linewidth',1.5)

plot(x,TSAS,'--m','linewidth',1.5) ....

xlabel('Dimensionless length X = x/H','FontSize',12)

ylabel('Dimensionless temperature','FontSize',12)

legend('Thetaf VP1 (t* = 2)','Thetas VP1 (t* = 2)','Thetaf MSLT (t* = 2)','Thetas MSLT (t* = 2)','Thetaf Air (t* = 2)','Thetas Air (t* = 2)','Thetaf VP1 (t* = 4)','Thetas VP1 (t* = 4)','Thetaf MSLT (t* = 4)','Thetas MSLT (t* = 4)','Thetaf Air (t* = 4)','Thetas Air (t* = 4)',1)

Help me..

 plot(rand(10,3));
 legend({'a','b','c'},'Orientation','horizontal');

Please read the documentation.

Yes it works, but it gives me a long Legend that is not fully visible in the graph only half and the other cache??

[José-Luis]

Either place your legend somewhere outside your plot (see the 'Location' option in the documentation) or split every entry into multiple lines:

 plot(rand(10,3));
 legend({['multi' char(10) 'line' char(10) 'entry'],'b','c'},'Orientation','horizontal');

You could also change the size of your figure so you have more space.

I do everything that you tell me. But I didn't understand this line plot(rand(10,3)); and what is the 10 ['multi' char(10) 'line' char(10) 'entry']... I apologize for this inconvenience, because I am a beginner in Matlab i don't know several tricks... sorry

[José-Luis]

 plot(rand(10,3))

plots three random lines, for which three legends will be needed.

The legend is given as a cell array of strings

 {['multi' char(10) 'line' char(10) 'entry'],'b','c'}

The string for the first item in the legend is split in three lines.

 char(10)

is the newline character.

You need to adapt this to your needs. Give it a shot.

Okay, I'll try... so thank you infinitely for all this information ^^

As of release R2018a you can set the NumColumns property of a legend to control in how many columns the legend entries are arranged. This should help with the "long legend" problem described in this first comment on this answer.
