How to Save Multiple Figures in Loop?
显示 更早的评论
Could you help me to save multiple plot/figure files using loop number?
My code is:
clear all;clc;
k=1:1:10
for i=1:15
x=i*sin(i*pi/4)*k;
y=i*2*cos(i*pi/2)*k;
plot(x,y)
sprintf(gcf, '-dtiff', 'File%d_6.tiff',i);
end

Perhaps this instead —
saveas(gcf, sprintf('File%02d_6.tiff',i), '-dtiff');
Specifing the numeric field as '%02d' creates a two-digit numeric field and pads single digits with a leading zero. That should make it easier to sort and recover the files.

clear all;
clc;
k = 1 : 10
for i = 1 : 15
x = i * sin(i*pi/4) * k;
y = i * 2 * cos(i*pi/2) * k;
plot(x, y, 'b-', 'LineWidth', 2);
grid on;
drawnow;
% Save current graph to its own file.
fullFileName = fullfile(pwd, sprintf('Plot %2.2d.png', i));
exportgraphics(gcf, fullFileName); % gcf to save the whole figure window, or gca to save only the graph.
end
fprintf('Done!!\n')
Be aware that your code just plots a series of lines, not sine or cosine curves since sin(i*pi/4) is just a single scalar, not a vector of 10 or 15 values, like perhaps you were expecting.
Use "hold on" after the plot if you want to show all the plot curves on the same graph.
