How to plot two graphs in one subplot?
显示 更早的评论
I would like to plot two graphs in one subplot to compare the parameters of two cars. However, the program does not give the expected outcome. It could only generate one graph in the subplots. How should I correct the program? Thanks!
(I would like to have combined plots similar to the image below.)

The same way you would add 2 lines to a plot that is not create using subplot - by either using hold or the following plot syntax:
x=-3:.1:3;
y1 = sin(x*pi/3);
y2 = cos(x*pi/3);
% option 1
plot(x,y1)
hold on
plot(x,y2)
hold off
xlim([-4,4])
% option 2
figure
plot(x,y1,x,y2)
xlim([-4,4])

Thanks for your reply! Actually, I would like to first plot six graphs (subplots) in a figure, and then add extra graphs to the subplots, but it turns out that the original graph disappeared. How can I solve this problem? (the program is attacted)
More details would be helpful. Otherwise, the answer I gave previously is still true. See the example below.
x=-3:.1:3;
y1 = sin(x*pi/3);
y2 = cos(x*pi/3);
subplot(2,1,1)
plot(x,y1)
xlim([-4,4])
subplot(2,1,2)
plot(x,y1)
xlim([-4,4])
% Add 2nd line to each plot
subplot(2,1,1)
hold on
plot(x,y2)
hold off
subplot(2,1,2)
hold on
plot(x,y2)
hold off

You call variables from the workspace, not the file. Therefore, any script can create the variable, but it must be in your workspace when you try to plot it. The challenge here is going to be ensuring you design and run both scripts correctly so that it works as intended.
You may also consider saving your variables to a mat file in the first script, then loading them in the second script.
