MATLAB: Problem with individual colour display in Legend for scatter plot (2014b)

Question

I am plotting a scatter plot within a loop and then assigning a legend outside the loop for all the data (15 sets). In previous versions of Matlab the legend would match the colours used in the scatter plot to differentiate between the 15 datasets. In the latest release the legend only shows one colour for each dataset (despite the plot showing different ones).

Anyone know a reason/workaround?

code…

C=[1:1:15]; subplot(212); hold on

for i=1:15;

    if ~isempty(Pro_PT(1,i).BurstTime);
        B=repmat(C(i),length(Pro_PT(1,i).Stats(:,2)),1);
        scatter(Pro_PT(1,i).Stats(:,2),Pro_PT(1,i).Stats(:,3),15,B,'filled','o');
        leg{i}=['PT ',num2str(i)];L{i}=i;
    else
        leg{i}=num2str(NaN);L{i}=NaN;
    end

end a=~isnan(cell2mat(L)); l=leg(a); legend(l,'Location', 'NorthWest','FontSize',6);

Answer 1

Here is the workaround again with the code formatting cleaned up.

C=[1:1:15]; subplot(212); hold on
cm = parula(15);
colormap(cm)
for i=1:15;
  if ~isempty(Pro_PT(1,i).BurstTime);
      B=repmat(cm(i),length(Pro_PT(1,i).Stats(:,2)),1);
      scatter(Pro_PT(1,i).Stats(:,2),Pro_PT(1,i).Stats(:,3),15,B,'filled','o');
      leg{i}=['PT ',num2str(i)];L{i}=i;
  else
      leg{i}=num2str(NaN);L{i}=NaN;
  end  
end
