If the data are already grouped, create a Column chart type.
The Histogram tool is used when you have ungrouped, raw data. It prepares a
frequency distribution, i.e., it groups the data, and then it creates a
Column chart.
If you have the original, ungrouped, raw data, you can use the Histogram
tool, or you could use my free Better Histogram add-in, available at
www.treeplan.com.
