评论： Ali 2017-10-29

I am looping through a bunch of data and want to use different marker styles (e.g. dots vs. crosses, etc.) for different categories of data. For example, for category A, I use this code:

            scatter(ZpercCat(sesh),norm_amp(sesh),'MarkerEdgeColor',rgb, ...
                'MarkerFaceColor',rgb)

to plot normal circles, and then I want to use crosses for category B using this code:

            scatter(ZpercCat(sesh),norm_amp(sesh),'MarkerEdgeColor',rgb, ...
                'MarkerFaceColor',rgb,'markertype','x')

but get the following error:

Error using specgraph.scattergroup/set
The name 'markertype' is not an accessible property for an instance of class
'scattergroup'.
Error in specgraph.scattergroup (line 26)
set(h,args{:});
Error in scatter (line 83)
      h = specgraph.scattergroup('parent',parax,'cdata',c,...

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);
