In JMP, the background color of the report window and the background color of the graph are set to different colors by default.
If you want to change the background color, for example when copying a graph to use in another application, please adjust the background color in JMP's preferences.
How to change the background color of windows and graphs
1. Select File > Preferences (Windows) or JMP > Settings (macOS).
2. Select "Style" on the left side of the preferences window, and then change the "Graph background color" and "Window background color" displayed on the right.

3. Click [Apply] to review the changes, and if everything is correct, click [OK] .
