How to Fix Incorrect Data Series in Excel Combination Charts on Mac
Question details
The user needs to correct data series values in an Excel combination chart where chart references are assigned to the wrong cell ranges.

- Product
- Excel
- Device & OS
- Mac
- Scenario
- Creating or modifying a combination chart (incorporating line and scatter series) from a selected data range.
- Observed behavior
- The chart series references point to incorrect cell ranges, causing the line and scatter series to display wrong values due to the application misinterpreting data rows and columns.
Ensure that your data is neatly organized in adjacent rows and columns, with clear headers for X and Y values, before generating or editing your combination chart.
Edit Data Series References via Select Data
Directly reassign the correct cell ranges for your X and Y values to fix incorrect chart visualizations.
When Excel automatically generates a combination chart, it might incorrectly guess which cells belong to the X-axis and Y-axis. Manually editing the data source allows you to explicitly define the correct ranges for each series.
Click on your combination chart to select it, which will reveal the Chart Design tab in the top ribbon.
Click on 'Select Data' in the Chart Design ribbon. Alternatively, right-click the chart and choose 'Select Data' from the context menu.
In the Select Data Source dialog box, select the incorrect data series and click the Edit button. Manually assign the correct cell ranges for the Series Name, X values, and Y values.
For any XY Scatter series in your chart, meticulously check that both the X-value range and Y-value range are pointing to the correct columns, then click OK to save.

Switch Row and Column Orientation
Use this method if the application has interpreted your data's rows as columns (or vice versa) during chart creation.

Frequently Asked Questions
Why does my Excel chart select the wrong data range automatically?
Spreadsheet applications try to guess the data structure based on adjacent cells. If headers are merged, missing, or irregular, the software might interpret rows as columns or grab extra unwanted data points.
How do I combine a line and scatter chart properly?
First, insert a Combo chart. Then, in the Select Data or Change Chart Type menu, assign one series to act as a Line chart and the other as an XY (Scatter) chart, ensuring they use the correct axes and data ranges.
Can I fix chart data series on Mac using the same shortcuts as Windows?
The core functionality is the same, but the interface on Mac is slightly different. You can still right-click the chart and choose 'Select Data' or use the Chart Design ribbon tab to access the data source settings.
