Fix Excel Combo Chart Series Not Showing in Change Chart Type
Question details
The user needs to modify individual chart types for series in a combination chart, but the series do not appear in the 'Change Chart Type' dialog despite being listed in the 'Select Data' window.

- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Modifying a combination chart containing multiple series (such as one column series and two line series) to adjust individual visualization settings.
- Observed behavior
- The chart series are entirely omitted from the 'Change Chart Type' dialog, preventing the user from changing the chart type for specific data sets.
Verify that your data series are correctly registered by right-clicking the chart area and clicking 'Select Data' to ensure all series are checked and active.
Access Change Chart Type via Direct Series Selection
Bypassing the main ribbon menu and directly interacting with the specific series on the chart forces Excel to recognize and display the series properties.
Often, the global 'Change Chart Type' dialog fails to load all series due to a interface glitch. Targeting the specific series directly from the chart area usually resolves this.
Click directly on one of the visible data series (like a column bar or a line) within your existing combination chart.
Right-click the highlighted data series to open the pop-up context menu.
Choose 'Change Series Chart Type' from the right-click menu. The dialog should now open and display your selected series, allowing you to modify it individually.

Test for Workbook or Chart Corruption
If the direct selection method still omits the series, the specific chart object or the entire workbook may be corrupted and needs to be rebuilt.
Create Combo Charts Seamlessly with WPS Office
If you frequently encounter missing series, chart bugs, or corrupted files in Microsoft Excel, consider switching to WPS Office. It is a lightweight, reliable alternative that handles complex data visualizations flawlessly without the frustrating interface glitches.
- 1. Install WPS Office: Download and install the free WPS Office suite from the official website.
- 2. Open your workbook: Launch WPS Spreadsheet and open your existing Excel workbook containing the chart.
- 3. Edit the chart type: Right-click your chart and select 'Change Chart Type' to safely edit your combo series without missing data.

Frequently Asked Questions
Why is one of my data series invisible on the combo chart?
This usually happens when the numerical values of your secondary data series are significantly smaller than the primary series, making them visually flat against the axis. To fix this, you need to assign the smaller series to a Secondary Axis.
How do I add a secondary axis to an Excel combo chart?
Right-click the specific data series on your chart, select 'Format Data Series', and in the Series Options pane that appears on the right, toggle the axis option from 'Primary Axis' to 'Secondary Axis'.
Can I combine more than two different chart types in one graph?
Yes. While combining a line and a column chart is the most common use case, you can combine multiple compatible chart types. Open the 'Change Chart Type' dialog, select 'Combo', and use the dropdown menus next to each series name to assign different chart types.
What causes an Excel workbook or chart to become corrupted?
Corruption can occur due to sudden power loss, frequent crashing, excessively large file sizes, or conflicting add-ins. Rebuilding the chart in a fresh workbook or opening the file in a compatible alternative like WPS Office often bypasses the corruption.
