Create a band chart in Excel
An Excel band chart can help us to quickly figure out if a series of data is within a certain range at a glance. It is composed of lines and horizontal bands which filled in different colors to display different boundaries of the defined data range.
For example, the below band chart displays the customer satisfaction for three products in a year. The green band in the chart represents high satisfaction for products, the yellow band represents the average satisfaction, and the pink band represents the low satisfaction. You can easily judge a series of data in the chart based on the band colors they locate rather than comparing each line marker with the vertical axis data.
The below step-by-step guide will show you how to create a band chart in Excel.
Prepare data for the band chart
Supposing you have a customer satisfaction survey table as the below screenshot shown.
Besides this data table, you need to add helper columns to represent the different boundaries of the defined data range. In this case, I add three helper columns to the original data table. These three columns will build up three bands in chart.
As the above screenshot shown, the percentages that are lower than 60% represent low satisfaction from customer. The percentages that are between 60% and 80% represent the average satisfaction. And the percentages that are higher than 80% are the high satisfaction. They occupy 60%, 20% and 20% of the total percentage (100%) respectively. You can arrange your own data based on your needs.
Create the band chart
1. Select the whole data range (including headers), go to the Insert tab and click Insert Combo Chart > Clustered Column – Line.
Now the chart is displayed as below.
2. Right click the chart and select Change Chart Type from the context menu.
3. Then the Change Chart Type dialog box pops up, in this dialog box, you need to:
- Choose the Line with Markers option for the product A, B and C series separately;
- Select the Stacked Column option for the Low, OK and High series;
- Click the OK button. See screenshot:
4. Click to select any one of the column, right click it and select Format Data Series from the right-clicking menu.
5. Then the Format Data Series pane displays on the right side in Excel, please change the Gap Width to 0% and then close the pane.
Now the columns are displayed as bands as the below screenshot shown.
6. Adjust the vertical axis range to make the chart clearer. Click to select the vertical axis placeholder, right click it and choose Format Axis from the context menu.
7. In the popping up pane, specify the Minimum and Maximum values based on your needs.
In this case, I want the vertical axis starts from 35% and ends with 100%, so I enter 0.35 and 1.0 separately into both the Minimum and Maximum boxes, and finally get the result as follows.
8. You can adjust the other elements of the chart. For example, you can:
8.1) Add the chart title. You just need to select the title placeholder and then replace the text with your own;
8.2) Change the color of the bands and lines as you need;
8.3) Add data labels to the bands if you need. The below steps will show you how to do it.
A. Click on a data label twice to only select it in the whole data series;
B. Go to the Design tab and click Add Chart Element > Data Labels > Center;
C. Click the label twice (the label you just added), right click and select Format Data Labels;
D. In the Format Data Label pane, only check the Series Name box. Then close the pane;
Repeat the above steps to add labels to other bands.
Here is the complete band chart.
