MATLAB: Creating a Bell Curve of Data

Question

Hello. I have a large set of temperature observations called tmax (26298×1 double) and I want to make a bell curve of all the data to see what it looks like. I've done a lot of browsing and can't find a simple way to do this. Does anyone have help on this? Thank you!

Just looking at your data, histogram() function is useful.

histogram(tmax01,30);%however many bins you want

You could overlay:

pd = fitdist(tmax01,'Normal');
x_values = min(tmax01):.1:max(tmax01);%not sure what step to use
y = pdf(pd,x_values);
hold on;
plot(x_values,y,'LineWidth',2);
histogram(tmax01,30);
