How to Create a Floating Range Chart in Excel
Question details
The user needs to create a chart that displays a floating range between minimum and maximum values, similar to a GraphPad Prism range chart or a box and whisker graphic.

- Excel
- Device & OS
- not provided
- Scenario
- Visualizing data ranges where only the segment between a minimum and maximum value is displayed as a floating bar on the chart.
- Observed behavior
- The desired visual effect can be achieved by customizing a stacked bar chart using a helper column and making the base data series transparent.
Ensure your dataset clearly defines the minimum and maximum values for each category before building the chart, as these are required to calculate the floating range.
Build a Floating Range Chart using a Stacked Bar Chart
Use a stacked bar chart combined with a helper column to calculate the difference between your maximum and minimum values, then hide the base series to create a floating effect.
This method simulates a floating range by stacking two data series and making the bottom one invisible. It is highly customizable and works across all versions of spreadsheet software.
In your dataset, add a new column named 'Difference' or 'Range'. Calculate the difference by subtracting the minimum value from the maximum value (e.g., using the formula =Max-Min).
Select your category labels, the minimum value column, and the newly created difference column. Navigate to the 'Insert' tab and choose 'Stacked Bar' or 'Stacked Column' from the charts section.
Click on the data series representing the minimum values (the bottom or left part of the stack in your chart) to select it. Right-click and choose 'Format Data Series'.
In the formatting pane, navigate to the Fill & Line settings. Set the 'Fill' to 'No fill' and the 'Border' to 'No line'. The visible range will now appear to float.
If necessary, double-click the vertical or horizontal axis to adjust the minimum and maximum bounds, or check the 'Categories in reverse order' box to match your desired layout.
Build Floating Range Charts for Free in WPS Office
WPS Spreadsheet provides powerful and intuitive charting tools, allowing you to easily create complex visualizations like floating range charts using stacked bars. It is fully compatible with Excel files and completely free to use.
- 1. Prepare Your Data: Open your dataset in WPS Spreadsheet and add a helper column that calculates the difference between the maximum and minimum values.
- 2. Insert a Stacked Chart: Highlight your categories, minimum values, and difference values. Go to the 'Insert' tab, click 'Chart', and select the 'Stacked Column' or 'Stacked Bar' option.
- 3. Format the Series: Select the minimum value series on the chart, open the right-side formatting pane, and set both the Fill and Line options to 'None' to create the floating effect.
Frequently Asked Questions
Can I create a true Box and Whisker chart directly in Excel?
Yes, modern versions of Excel (2016 and later) have a built-in 'Box and Whisker' chart type under the 'Insert Statistic Chart' menu. However, the floating stacked bar method is still widely used because it offers greater manual control over formatting and works on older software versions.
Why do my floating bars start from zero instead of the minimum value?
This usually happens if you did not include the minimum value series in your stacked chart. Ensure you are plotting both the 'Minimum' column and the 'Difference' helper column, then set the 'Minimum' series to have no fill.
How do I add data labels to the top and bottom of the floating range?
You can add data labels to the invisible 'Minimum' series for the bottom values, and to the visible 'Difference' series for the top values. Adjust their label positions to 'Inside Base' or 'Inside End' in the data label formatting options.
