Only the initial graph shows up
显示 更早的评论
I'm trying to subplot 2 graphs in the same figure but I'm only getting the first graph. Need help trying to display both graphs
figure;
subplot(2, 1, 1)
plot(frames, Knee_A(:, 1), 'ro-', 'linewidth', 2); hold on;
plot(frames, Knee_A(:, 2), 'go-', 'linewidth', 2);
plot(frames, Knee_A(:, 3), 'bo-', 'linewidth', 2);
xlabel('Fluoroscopic Frame (30 FPS)');
ylabel('Angle (deg)');
legend('Flex/EXT', 'ADD/ABD', 'IR/ER', -1);
title([handles.SubjectName, ' ', handles.SubjectSide, ' ', handles.TrialName, ' Knee Angles']);
subplot(2, 1, 2)
plot(frames, Knee_V_tibia(:, 1), 'ro-', 'linewidth', 2); hold on;
plot(frames, Knee_V_tibia(:, 2), 'go-', 'linewidth', 2);
plot(frames, Knee_V_tibia(:, 3), 'bo-', 'linewidth', 2);
xlabel('Fluoroscopic Frames (30 FPS)');
ylabel('Translation (mm)');
% plot(frames, sum(StemV_cup.^2, 2).^.5, 'ko-', 'linewidth', 2);
title('Knee Translations')
legend('A/P', 'P/D', 'L/M', -1);

The problem is that you have an error in your line
Error using legend
Invalid argument. Type 'help legend' for more information.
Error in missingplot (line 11)
legend('Flex/EXT', 'ADD/ABD', 'IR/ER', -1);
Specifically the -1 at the end is not correct. So the script crashes before it ever makes the second subplot.
Note the line number this occurs in for your code is probably not 11, I added a few lines ahead of your script to make up some data. Anyhow, it is the line that has the legend command. Same thing for legend in second subplot

Also obviously your script is not called missingplot, that is just what I called my script that I saved using your code in order to debug it.

@Jon good catch.
@Pete Tuchinda: Lesson learned - pay attention to error messages and always include the full copy-pasted error message in your question.

numbers as the final parameter to legend() used to indicate the plot position. I think -1 corresponded to the current "best" request

So using current MATLAB versions (R2022a)
legend('Flex/EXT', 'ADD/ABD', 'IR/ER','Location','best');
