Hi,
How did the user create the chart? Did only the chart occur the issue?
- Create the chart the Excel and copy it to PowerPoint 2013.
- Create the chart directly in PowerPoint 2013.
I had tested both of the two ways and it displayed correctly in PowerPoint 2010.
Thus, I recommend you follow the below steps to check the issue:
1. Create a new create with new data to test again. If every chart occurs the issue, I recommend you check the PowerPoint 2010.
- Start PowerPoint 2010 in safe mode. If it works fine, the issue may be caused by the add-ins, please check the add-ins one by one.
- Upgrade the Office 2010 patches and repair Office 2010.
2. If the issue only occur in the chart, please try to copy the chart to a blank PowerPoint 2010 or follow the below link to re-create the chart the test.

If the issue still exists, please upload a sample presentation include the chart through OneDrive, I'll test in my environment.
