I want to plot lines that differ in both linestyle and linecolor (because if someone makes a b&w copy of the paper, they lose the linecolor information). If I specify a set of linestyles, plot cycles through all the colors on the first style, then all the colors on the second style, and so on. It would be really convenient if I could specify a default sequence of lines that include BOTH style and color; e.g.,
blue solid line
red dashed line
green dotted line
yellow dash-dot line, etc.
I want to be able to do this with Matlab's automatic line rendering, not plotting one line at a time, specifying the details for each one.
Does anyone know of a way to do this? Has anyone created a routine to do it?

To answer the last question you can write your own plot function as i have below:
function hplot = cblindtest(pnts)
hplot = plot(pnts);
% styles:
% b blue . point - solid
% g green o circle : dotted
% r red x x-mark -. dashdot
% c cyan + plus -- dashed
% m magenta * star (none) no line
% y yellow s square
% k black d diamond
% w white v triangle (down)
% ^ triangle (up)
% < triangle (left)
% > triangle (right)
% p pentagram
% h hexagram
clor = 'bgrcmyk';
disp('debug')
linestyle={'-',':','-.','--'};
markertype = ' .ox+*sdv^<>ph';
mind = 1;
for ind = 0:length(hplot)-1
set(hplot(ind+1),'color',clor(mod(ind,7)+1));
lind = mod(ind,4);
set(hplot(ind+1),'linestyle',linestyle{lind+1});
if markertype(mind)==' '
mtype = 'none';
else
mtype = markertype(mind);
end
set(hplot(ind+1),'marker',mtype);
if mod(ind+1,4)==0;
mind = mod(mind,14)+1;
end
end
which can be run with
figure()
pnts = randi(6*13,1,1);
pnts = repmat(1:pnts,3,1);
cblindtest(pnts)
xlim([0 4])
edit as desired

you can do it by setting the line order style. Here an example:
set(gca,'linestyleorder',{'-',':','-.','--','*','+'},...
'colororder',[0 0 1;0 .5 0;1 0 0],'nextplot','add')
x = 0:.01:1;
plot(x,bsxfun(@power,x.',1:12))
in this example at first the '-' is set and then the colors are changed from blue to red for the first three lines. From the fourth to the sixth line the ':' styli is selected and the color will be changed. Hopefully it will helps

Did you ever figure this one out?
If so, I would love to hear your solution.

A semi-automatic code I have came up:
% define line style or color you want
sty = {'-', '--', '-.',':'};
col = {'#0072BD', '#D95319', '#EDB120', '#7E2F8E'};
% loop through your plot
for i = 1:4
plot(x, y, string(sty(i)), 'Color', string(col(i)))
% x, y can be vectors changin according to i
% ofc if i > 4, you can do something like mod(4, i) to make the index
% go back again.
end
It's essentially the same as Cheng's answer, but I made it this way so you can edit the color other than the bgrcmyk colors
