Legend for plot genereted by a loop
显示 更早的评论
I want to plot 2 variables and each row of the 2 variables to be presented with different color. So I wrote the following code which plot through loop:
plot(Xindex2plot,Yindex2plot,'color',cc(allSS,:));
However, I have problem with the legend. At legend it is presented only the color of the last row of data and the text respectively. This is the code for the lgend which it is supposed that produced through loop also.
% s{allSS}=sprintf('%s',nameofsource2open);
% legend(plotall,s)
How I should reform it to present all the data and the texts?
Thank you in advnace

Store a handle to each plot in h(i) and let the legend refer to this handle h:
col = rand(3, 3);
data = rand(3, 100);
axis, hold on, for i=1:3, h(i) = plot(data(i,:), 'Color', col(i,:)); end
legend(h, {'data1' 'data2' 'data3'})

In the loop:
legendtext{i} = variable_that_changes;
and then
legend(h, legendtext)
