Histograms are used to organize data in a way that is easy to understand. A histogram tells you the frequency or how often an event occurs. The frequency values are organized as bins or ranges of values. When you create a histogram in Excel, it automatically creates bins based on the data. You may want to change the bin size to make the chart easier to understand.
Step 1 – Open the Format Axis box
– On the chart, click on the axis
– Right-click and select Format Axis from the context menu
Step 2 – Change the bin width
– Increase the bin width to 10
Step 3 – Check the result
– The size of the bins changes to 10
