- Product
- Microsoft PowerPoint
- Device & OS
- not provided
- Scenario
- Presenting a slide that contains a line chart or scatter chart with high-low lines enabled.
- Observed behavior
- The chart appears fine while editing, but the high-low lines overlap the dot markers during Slide Show mode due to a rendering glitch in specific Office builds.
Ensure you have saved your presentation progress. Try opening the slide on a different monitor or duplicating the slide to verify that the overlap is not caused by a temporary display glitch.
Update Microsoft PowerPoint to the Latest Build
Since this overlapping issue is directly tied to the rendering engine of specific Office builds, updating PowerPoint to the latest version is the most reliable fix.
Microsoft frequently releases patches for visual glitches in Slide Show view. Testing confirms that the overlap does not occur on the latest PowerPoint versions.
Launch Microsoft PowerPoint and click on 'File' in the top-left corner, then select 'Account' from the left-hand menu.
Under the Product Information section, click the 'Update Options' button.
Select 'Update Now' from the drop-down menu and wait for Office to download and install the latest bug fixes.
Modify Chart Type and Disable Gridlines
If your organization restricts Office updates, tweaking the chart type and removing gridlines can bypass the rendering bug.

Frequently Asked Questions
Why do my PowerPoint charts look different in Slide Show mode compared to Normal view?
PowerPoint sometimes uses different rendering processes for editing (Normal view) and presenting (Slide Show view). In certain Office builds, this can cause visual discrepancies like overlapping lines or shifted markers.
How do I add or remove high-low lines in a PowerPoint chart?
Select your line chart, go to the 'Chart Design' tab, click 'Add Chart Element', hover over 'Lines', and select 'High-Low Lines'. To remove them, follow the same path and choose 'None'.
Will saving the presentation as a PDF fix the chart overlap?
Yes, exporting the slide as a PDF captures the chart exactly as it appears in Normal view, bypassing the Slide Show rendering glitch. You can present the PDF in full-screen mode as a temporary workaround.
