Both are real .pptx files, built from the same made-up numbers. The faulty one was built on purpose.

Everything on a slide lines up on one grid.

12 columns and 0.6 inch margins. Move the lens to see the boxes in the .pptx file.

0of 9 left edges off the grid

The chart axis can change the story.

The numbers stay the same as you drag. The skill starts a bar chart at zero and a waterfall chart just below its lowest bar. Drag the axis.
