Take a look at the MATLAB Plot Gallery, in particular the stacked bar chart example. (I think you want a bar chart, not a histogram.) If you click on View Source underneath that plot, you will see the code that generated that plot, and you can probably adapt that to your need.
There are a number of ways to import the data. If you don't know how to do that, maybe ask a separate question, or take a look at the documentation about data import.
