-===== 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.
-{{ :plots.png?500 |}}
- 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 …….
