How to plot a mixed density function?

Hi

So, lets say I get 10000 random numbers:

-5000 from normal distribution with mean = 1 and sigma = 1

-5000 from normal distribution with mean = 4 and sigma = 1

Now I have to plot density function.

I know how to plot single density function, not a mix.

Can you help me?

Thanks,

Lukas

h = histogram(data,'Normalization','probability')

x=-6:.01:10;
pdf1 = normpdf(x,1,1);
pdf2 = normpdf(x,4,1);
mixpdf = 0.5*pdf1 + 0.5*pdf2;
figure;
plot(x,mixpdf);
