MATLAB: Change histogram graph to smooth curve

hist to plot

I have this code to sum 10 independent uniform random variables to verify the central limit theorem but I could not change the code to get a curve plot instead of the histogram this is the code
uniform_RVs = [];
sample_averages = [];       
random_draw = [];       
for i = 1:500      
   for j = 0:20     
random_draw = [random_draw 4.*rand];    
end 
sample_averages = [sample_averages mean(random_draw)]; 
uniform_RVs = [uniform_RVs random_draw];    
 random_draw = [];
end
figure(1) 
hist(uniform_RVs, 25) 
xlabel('Observation') 
ylabel('Frequency') 
figure(2)
 hist(sample_averages, 25) 
xlabel('Observation') 
ylabel('Frequency') 
sample_mean = mean(sample_averages) 
sample_var = var(sample_averages)
Please help me
