Histogram chart

The histogram chart is a niche chart mostly used to visualize the distribution of a set of values. If you have income data of over 200,000 people in your market catchment area, you might want to plot a histogram chart on the data to see the income brackets most people fall into. So, if you have sales data for the last quarter and you are trying to help the business set an appropriate order volume at which a discount promotion should kick in, a histogram will come in handy by showing you what that order volume target should be.

In Figure 8.38, we see a histogram used to visualize the distribution of order value across sales made within a particular period. This can be useful for a business to understand customers’ purchase patterns:

That will be it for histograms; we will move on to the next chart.
