I want to plot (u vs time) for each i's in a single graph together.The problem is, how can I give separate color, line type for each i's, here is the code which I tried to work upon. thanks

 datafiles = dir('datarus*_qsStruc.mat');
   for i = 1:length(datafiles)
    load(datafiles(ii).name)
    u = qsStruc.beta; 
    time = qsStruc.time;
    plot(u,time,'o');

在 MATLAB Online 中打开

datafiles = dir('datarus*_qsStruc.mat');
nfiles = length(datafiles);
% Get plot colors from a colormap
mycolors = lines(nfiles);
for ii = 1:nfiles
  load(datafiles(ii).name)
  u = qsStruc.beta; 
  time = qsStruc.time;
  % Set the color to the corresponding entry from the colormap
  plot(u,time,'o','color',mycolors(ii,:));

Replace "lines" with whatever colormap suits your fancy.

Or, as was suggested in your earlier question, use plt() which is designed to be able to automatically generate combinations of color and markers and line styles in order to distinguish many different lines.
