rename plot names in a loop

How can I rename my figures in a loop after plotting my data?

I want the them to be called 'Data 1','Data 2','Data 3'.

Store the handles of the figures in a vector:

FigList = gobjects(1, 3);
for k = 1:3
  FigList(k) = figure;
end

% Then the naming is easy (but could be done in the loop above already?!)
for k = 1:3
  FigList(k).Name = sprintf('Data %d', k);
end

People often use the term "figure" to refer to either the figure window or to the axes contained in the figure window. Jan's code addresses the first usage. If you have multiple axes and you want to label each with a title, use the title function either right after you create the plot or at the end (using the axes handle.)

x = 0:360;
ax = gobjects(1, 2);

ax(1) = axes;
axis(ax(1), [0 360 -1 1])
plot(ax(1), x, sind(x))

figure
ax(2) = axes;
axis(ax(2), [0 360 -1 1])
plot(ax(2), x, cosd(x))

title(ax(1), "Sine")

title(ax(2), "Cosine")
