Creating a box chart (Box and Whisker Plot) is not difficult in Excel, especially since Excel 2016, Microsoft has built-in this chart type. You just need to prepare the data and select the right operation steps to quickly generate clear visual results.

Data preparation is key

Box charts are used to show the data distribution, so you need a set of numerical data. It can be a column of data or multiple sets of data in parallel to compare the distribution situations of different categories.

For example: If you want to compare the math scores of three classes, you should have three columns of data, each column represents a list of grades for a class.

A few suggestions:

• Try to be clean to avoid null values ??or text mixing
• There is no need to sort in advance, Excel will automatically handle it
• Try to be as close as possible to the effect more accurately

Steps to insert a box diagram

Inserting a box line chart in Excel is very direct. As long as the data is sorted out, you can complete it in a few steps.

The operation process is as follows:

• Select your data area (including title)
• Click "Insert" in the top menu bar
• Find the "Statistical Chart" category in the chart area
• Click "Box and Whisker"

At this time, Excel will automatically generate a box graph. By default, it displays medians, upper and lower quartiles, outliers, etc. for each dataset.

If you are using an old version of Excel (such as 2013 or earlier), you have to manually use the bar chart error bar to simulate the box chart. The process is more complicated, but not too difficult.

Chart details can be adjusted

The newly generated box chart may look a little simple, but you can personalize it by right-clicking on the chart element.

Common adjustments include:

• Modify colors and styles to make the chart more beautiful
• Adjust the axis range and highlight key areas
• Show or hide outliers
• Change the display method, such as whether to display the mean mark

Double-click the box part in the chart to open the "Set Data Series Format" panel, where you can choose different calculation methods, such as whether the average value is included, or modify the calculation method of the quartile (including median interpolation, etc.).

Basically that's it. The whole process is not complicated, but details of data format and chart options are easily overlooked. Just pay attention to these points and you can easily make professional box charts in Excel.
