Plots
Plots allow the user to graphically compare two variables together. The basic syntax is
plot(X , Y, S).
X is an array consisting of x coordinates and Y is an array consisting of Y coordinates. S allows the user to select various line types. If you type in “help plot” in the command window you can see this section that explains the purpose of S.
From Matlab
You can also plot multiple Xs, Ys, and Ss using the following syntax.
plot(X1, Y2, S1, X2, Y2, S2, Xn, Yn, Sn);
When you create a plot Matlab will display it on a figure
The following are useful commands associated with plots
To adjust the x and y axis limits xlim( [Xmin Xmax]) ylim( [Ymin Ymax])
To write a header text(‘insert text here’)
Create labels on the x and y axis xlabel(‘insert label here’) ylabel(‘insert label here’)
place multiple graphs on the same figure hold on
create a legend legend(string1, string2, string, ‘location’, string_of_location) ‘location’ is to indicate that you will tell matlab where to put the legend
Specify which figure to use. figure(x); x = 1, 2, 3 …….
