How do I plot a histogram for large data sets?

Can anyone possibly help me with writing a code for my histogram?
I need to use matlab but I'm not familiar with histograms and the information page is not helping too much.
Essentially I have 355 data points, then the raw data for all those data points.
I want to plot Number of Cells against Fluorescence Intensity
x (Fluorescence Intensity)
y (Number of cells)
I can determine the directory and file name, but I do not know how to write the code to generate the histogram after that.
The data will be imported from an excel file, just FYI.

This is actually not a histogram. It is a bar graph you are looking for.

The basic difference between histogram and bar chart is:
Histogram refers to a graphical representation; that displays data by way of bars to show the frequency of numerical data. A bar graph is a pictorial representation of data that uses bars to compare different categories of data.
A Bar chart is apt for your problem. This should work.
dataset = xlsread('histogram data for glucose.xlsx');
x = dataset(:,1);
y = dataset(:,2);
bar(x,y);
