How to have number as marker symbol in plot

I'm trying to have a plot with number form 1 to 150 as a marker symbol.I have this but it doesn't work.please help

    if true
      % code
  mark=zeros(1,class_length);
  for i=1:class_length
      mark(:,i)=i;
      ma=num2str(mark);
      malength=length(ma);

   end

if mode==6 && colorflag==0
    box on;
    hold on;

      for i=1:class_length

          for p=1:malength
              if classlabel(i)==p

                  plot(x(i),y(i),'Marker',mo(p),'MarkerSize',fontsize,'Color',colors(7));

              end
          end

      end
      hold off;
    end

You cannot create custom market symbols for use with plot(). My understanding is that the File Exchange contribution plt() allows you to define custom marker symbols.

However, what you should be doing in your situation is using text() instead of plot(). You are, after all, only putting up text and not drawing any lines.

By the way, with your existing code, why are you looping testing class labels one by one? And where did "mo" come from? Why do you take length(ma) and then throw away ma itself and throw away the length as well?

If you could create custom markers, then why not,

    ma = cellstr(num2str(classlabel(:)));    %num2str can process vector

    for i=1:class_length
      plot(x(i),y(i),'Marker',ma{i},'MarkerSize',fontsize,'Color',colors(7));
    end

Though, as noted above, you cannot use custom markers: I am just illustrating that your code could have been more compact.

Suggested code replacement, for everything above that seems to have relevance:

if mode==6 && colorflag==0
  box on;
  text(x, y, cellstr(num2str(classlabel(:)))), 'FontSize', fontsize, 'Color', colors(7));
end

No loop needed.

Thanks a lot for the 'text' code. I've used the following to get the numbers printed next to my markers positioned at x(i) and y(i):

fontsize=10;

no_of_numbers=10

for i=1:no_of_numbers

text(x(i)+0.05, y(i), cellstr(num2str(i)), 'FontSize', fontsize);

end

Use text objects to add markers, e.g.:

x = 0:1:10;
y = sin(x);

plot(x,y,'-r')
hold on
for ii = 1:length(x)
    text(x(ii),y(ii),num2str(ii),'Color','r')
end

thank you so much

Ah so easy, thank you!

This idea of plotting text in plot is very useful to number data and sorting them out. Thanks :)
