histfit.fig

I curve fit 4 distributions over a histogram. Each time that I use histfit command, it shows the corresponding histogram as well and at the end I have repetitive legends! Can any one help how to get rid of the redundant ones? The code is pretty simple!

sz=xlsread('sz418.xlsx');
mm=sz(:,1);
aa=sz(:,2);
k=histfit(mm,10,'normal')
hold on
h=histfit(mm,10,'inversegaussian')
h(2).Color = [.8 .2 .8];
p=histfit(mm,10,'lognormal')
p(2).Color = [.1 .1 .1];
pd = makedist('Normal',mean(mm),std(mm));
t = truncate(pd,0,1.2)
x = 0:.01:0.5;
plot(x,10*pdf(t,x),'Color','blue','LineWidth',2,'LineStyle',':')
hold off

I tried running this code but didn't get the error. Initially I didn't even get the legend. I had to manually force it to appear by writing the the legend('show') command at the end of the above code. May be some of the options in the documentation link below may help
