How to create a Histogram in Excel

First, the Data Analysis "toolpak" must be installed.  To do this, pull down the Tools menu, and choose Add-Ins.

You need to have a column of numbers in the spreadsheet that you wish to create the histogram from, AND you need to have a column of intervals or "Bin" to be the upper boundary category labels on the X-axis of the histogram.  See example of spreadsheet below:

Pull Down the Tools Menu and Choose Data Analysis, and then choose Histogram and click OK.  Enter the Input Range of the data you want (In the example above it would be C5:C29) and enter the Bin Range (E5:E14 in example above).  Choose whether you want the output in a new worksheet ply, or in a defined output range on the same spreadsheet.  If you choose in the example above to have the output range H5, and you clicked OK, the spreadsheet would look like this:

The next step is to make a bar chart of the Frequency column (I6:I15 in the example above).  Block the frequency range, click on the graph Wizard, and choose Column Graph, click on Finish.  Delete the Series legend, right click on the edge of the graph and choose Source Data , and enter the Bin frequencies (H6:H15) for the X-Axis Category labels. Notice the labels have been manually altered to represnet a range (54-56) instead of just the upper boundary (56).  Right click on any of the bars and choose Format Data Series .  Choose the Options tab, reduce the Gap Width to zero and click OK.  
Dress up the graph by right clicking on the edge of the graph and choosing Chart Options.  Enter a complete descriptive title with data source, perhaps data labels, and axes labels.  You may also right click and format the color of the bars and background.  The completed Histogram should look something like this:
