Exporting a graph image from Vernier Video Analysis when using a Safari browser can result in incompletely drawn images. This behavior appears to be limited to Safari running on macOS and iOS/iPadOS.

Changing any setting of the exported image, such as Line Shade, will cause it to redraw, usually resulting in a complete drawing with all screen elements. You may need to choose a new setting, and then return it to your desired setting to get the image you want.
