How to Fix Excel Chart Not Showing Correct Data Source

In this tutorial, you'll learn about How to Fix Excel Chart Not Showing Correct Data Source. We cover key concepts, practical examples, and best practices.

Excel charts display data from a defined source range. When the chart shows the wrong data, ignores new rows, or displays empty series, the data source range needs to be updated or converted to a Table.

The Problem

Your chart shows data that does not match the current spreadsheet, or new rows you added are missing from the chart.

Wrong approach — recreating the chart from scratch.

The Fix

Use Select Data to verify and update the chart source:

1. Right-click the chart → Select Data
2. Check the Chart data range at the top
3. Verify each Series has the correct Series values and Category (X axis) range

For hidden rows, check if the chart is set to ignore hidden data:

1. Right-click the chart → Select Data
2. Hidden and Empty Cells button
3. Uncheck "Show data in hidden rows and columns"

To make the chart auto-expand with new data, convert the source to a Table:

1. Select your data → Ctrl+T → OK
2. Right-click chart → Select Data
3. Change data range to the table name: =Sheet1!SalesTable

For a wrong X-axis, edit the Horizontal (Category) Axis Labels:

Select Data → Horizontal (Category) Axis Labels → Edit
Select the correct range for labels

Expected output:

Chart reflects all current data including new rows
Hidden rows are excluded from the chart
New data added to the Table appears in the chart on refresh

Prevention Tips

• Convert chart source data to Excel Tables (Ctrl+T) for automatic range expansion
• Use named ranges in chart series formulas for simpler maintenance
• Check "Hidden and Empty Cells" settings when filtering data
• Keep chart data on the same sheet or in a consistent location
• Use dynamic named ranges with OFFSET or INDEX for non-Table data sources

Common Mistakes with chart data source

1. Using return to exit a function early instead of wrapping a pure value in the monad
2. Mixing let bindings with <- bindings in do notation, producing type errors
3. Overlapping type class instances that cause GHC to reject the program with ambiguous dispatch errors

These mistakes appear frequently in real-world EXCEL code. DodaTech's contributors have identified these patterns through analysis of open-source projects and production systems.

Practice Exercise

Write a pure function that safely divides two integers using Maybe, then test it with edge cases like division by zero and negative numbers.

This exercise reinforces the concepts covered in this guide. Try implementing it before checking online solutions.
