How to add a trendline to a histogram plot and not show the histogram?

I need to add a trendline to the histogram and becuase I have several datasets I want to remove the histogram and keep only trendlines.

Any idea?

Here is my solution

x = randi(100,1,100);
hist(x,20);
[y,x0] = hist(x,20);
hold on
plot(x0,y)
hold off
