This is what I combined from this forum:
set(0,'defaultaxeslinestyleorder',{'+','o','*','.','x','s','d','^'});
hold all
for n=1:8
p=plot(x,ddmax(:,n));
end
legend('1','2','3','4','5','6','7','8')
But what it produced is 7 '+' and a 'o', see picture. What did I do wrong?

x is 40; ddmax 40x8; see attached plot picture; 8 plots, needs 8 different markers;

--------------------------------------------------- code start This is an example for your case
Input is "Input_Data", two dimension matrix
Marker_Counter=1;
figure6=figure;
Markers = {'+','o','*','x','v','d','^','s','>','<'};
for i=1:10:size(Input_Data,1)
TPR=Input_Data(i:i+9,7);
FPR=Input_Data(i:i+9,8);
plot(FPR,TPR,strcat('-',Markers{Marker_Counter}));
Marker_Counter=Marker_Counter+1;
hold on
end
plot([0.5 1],[0.5 1],'--');
legend('Minpts = 100','Minpts = 200','Minpts = 300','Minpts = 400','Minpts = 500','Minpts = 600','Minpts = 700','Minpts = 800','Minpts = 900','Minpts = 1000','','Location','SouthEast');
xlabel('FPR or (1-Specificity)','FontSize',12,'FontWeight','bold'); ylabel('TPR or Spensitivity)','FontSize',12,'FontWeight','bold');
title('ROC Space');
close(gcf);

"Axes increments the line style only after using all of the colors in the ColorOrder property. It then uses all the colors again with the second line style, and so on. "

Still doesn't work.
set(groot,'defaultAxesColorOrder',[1 0 0;1 0 1;0 1 0;0 0 1],...
'defaultAxesLineStyleOrder','+-|o-|v-|s-|p-|h-|d-|^-')
plot(x,ddmax);
Bellow is what above script produced:
Bellow is what we wanted:

You cannot do that automatically. The next line style will not be looked at until all colors have been used once. There is no provision using the defaults to advance one marker for each color. You would need to set the properties of the line handles.

I had the same issue and got around by using this function made by Sébastien Martin.
Hope it helps you.
