how to get only selected legend in this particular case

I have attached data, can anyone help me getting red, blue and green legends only?

yt = logspace(-3,4,8);

binranges = yt; 
[bincounts] = histc((I(:,1)),binranges); 
h1 = bar(binranges,bincounts,'histc','FaceColor',[1 0 0]);
set(h1,'FaceColor','r','EdgeColor','r');
hold on;
[bincounts] = histc(1./(D(:,1)),binranges); 
h2 = bar(binranges,bincounts,'histc');
set(h2,'FaceColor','g','EdgeColor','g');
hold on;
[bincounts] = histc((NO(:,1)),binranges); 
h3 = bar(binranges,bincounts,'histc');
set(h3,'FaceColor','b','EdgeColor','b');
legend('show');
set(gca,'XMinorTick','on','YMinorTick','on','XScale','log');

The above code shows 6 legends for 3 dataset.

Can anyone give me only colors and no * mark.

Using explicit handles to the patch objects will fix the legend for you. Also, you don't need the second call to hold on. The last part of the code will delete all line objects in the plot. If you want to change the legend labels, look into the doc for the legend function.

S=load('matlab.mat');D=S.D;I=S.I;NO=S.NO;
figure(1),clf(1)

yt = logspace(-3,4,8);
binranges = yt; 
[bincounts] = histc((I(:,1)),binranges); 
h1 = bar(binranges,bincounts,'histc');
set(h1,'FaceColor','r','EdgeColor','r');
hold on;
[bincounts] = histc(1./(D(:,1)),binranges); 
h2 = bar(binranges,bincounts,'histc');
set(h2,'FaceColor','g','EdgeColor','g');
%hold on;%redundant, as the NextPlot property is already set
[bincounts] = histc((NO(:,1)),binranges); 
h3 = bar(binranges,bincounts,'histc');
set(h3,'FaceColor','b','EdgeColor','b');
legend([h1 h2 h3]);%use handles to patch objects
set(gca,'XMinorTick','on','YMinorTick','on','XScale','log');

children=get(gca,'Children');
types=get(children,'Type');
delete(children(ismember(types,{'line'})))
