Google Slides does not properly display think-cell charts

Problem

When a PowerPoint presentation containing think-cell charts is opened in Google Slides, some labels and lines in the think-cell charts might appear blurry and be misplaced.

Explanation

According to Google Support’s Work with Office files page, Google Slides will convert embedded charts in PowerPoint files to images.

Google Slides may not be able to handle some PowerPoint charts and the following problems may be observed after the conversion: Blurry and misplaced labels and lines, vertically compressed charts, additional horizontal gridlines, incorrect major/minor axis units, increased column width and decreased gap width between columns.

Since think-cell only uses PowerPoint charts and shapes to generate charts, Google Slides will also convert think-cell charts while opening PowerPoint presentations, so similar issues may also be observed.

The issues can be reproduced without think-cell, using a PowerPoint chart.

Reproduction without think-cell

  1. Open PowerPoint
  2. Insert a PowerPoint Clustered Column Chart by going to InsertIllustrationsChartClustered ColumnOK
  3. Right-click on the Y-axis and select Format Axis
  4. Set Maximum Bound to 9.5
  5. Set Minimum Bound to 0
  6. Set Major Unit to 2
  7. Right-click on a column and select Add Data LabelsAdd Data Labels
  8. Save the PowerPoint presentation
  9. Upload the presentation to Google Drive / Google Slides and open it with Google Slides
Result: The custom major unit for the Y-axis is ignored (the default value of 1 is used instead of 2). The Y-axis is extended to the next tick mark value, which is 10 in this case. This causes the chart to be compressed vertically and the labels get misplaced. Lines and labels appear blurry. The widths of the columns increase and the gaps between the columns decrease.

Workaround

As a workaround, open the presentation in PowerPoint and save a copy of it in the .ppt file format (instead of .pptx) before uploading it to Google Drive / Google Slides.

  1. Open the presentation in PowerPoint and then go to FileSave As
  2. Choose where you would like to save the file
  3. Select PowerPoint 97-2003 Presentation (*.ppt) from the Save as type: dropdown menu
  4. Click on Save
  5. If the Microsoft PowerPoint Compatibility Checker warns you about features that are not supported by earlier versions of PowerPoint, click on Continue
  6. Upload the .ppt file to Google Drive / Google Slides and open it with Google Slides

When a .pptx file is saved in the .ppt file format, PowerPoint saves images of the charts within the file, so Google Slides does not have to convert them anymore.

Please note that the .ppt extension is a legacy PowerPoint extension and that it might cause unintended consequences, so we do not recommend using it for other purposes.
