is it possible to increment color and markers automatically for a plot in a loop?

61 views (last 30 days)
I want to use a loop to plot a series of datasets eg
for jj=1:numel(data)
plot(data{jj}(:,1),data{jj}(:,2),[Marker Color])
end
I'd like to know if there is a built-in function that I could use in my plot command so that Color and Marker are automatically incremented and that at the end of the day each dataset has a different marker/color.
I could do this
markers = {'+','o','*','.','x','s','d','^','v','>','<','p','h'}
and then access it this way:
markers{mod(i,numel(markers))+1}
and something similar for the colors but it's kind of ugly
any comments ?

if true
--------------------------------------------------- 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);
-------------------------------------------- code end
end

In fact I think what really fits my need is
hold all

color='rmbc'
markers = '+o*.x'
t=0:0.1:10;y=sin(t);
plot(t,y,[markers(2) color(3)])

You can do this:
set(0,'DefaultAxesLineStyleOrder',{'+','o','*','.','x','s','d','^','v','>','<','p','h'});
Then look:
figure
x = 0:.01:1;
hold all
for ii = 1:10
plot(x,x.^ii)
end
You should see that the marker changes every time the line color cycles through the colors.

It won't change the marker until the default color pool has been cycled through. From the following post, if you just use one color type,
set(0,'defaultaxescolororder',[0 0 0]);
, then you can let the marker change every time.

Try this function, it worked out for me...
