How do I make this matlab code to plot multiple figures in subsequent 'while' iterations ?
显示 更早的评论
Hi. I'm a beginner in Matlab, I'm working on Image analysis and I think this code segment is supposed to display a plot in a figure everytime the if condition is met. I'M 100% sure that the if condition is met more than once but the program only gives a figure output the first time the if condition is met. It does not gives outputs when the if condition is met in subsequent iterations. It also does this wierd thing where it dsplays the first figure but without the plot in it and only displays the corresponding plot in the figure when the program has finished running. Like I said, I'm a beginner and I have a feeling that this is a minor problem but I just can't figure it out.Please any help will be appreciated. To be clear, I'm trying to plot different data in different figures whenever the if condition is met but it only plots the first time the if condition is met and does nothing in subsequent times.

drawnow()
possibly figure() as well

If you see only the first figure, probably the condition is getting met just once. Or maybe you are just seeing the last figure?

You should write figure() for every if statement to display corresponding image. So, just write at the begining of the statement like this. As far as I understand you want seperate images thats why I believe hold off should be inside the if.
if ref_image{f,3} == inactivity_time
figure
axis image;
disp(n)
imshow(originalImage_new);
hold on;
plot_pixels = ref_image{f,1};
plot(plot_pixels(:,1),plot_pixels(:,2),'*r');
hold off
end
