Why is my chart legend wrong?
Common causes:

Column B

Ctrl + Shift + R
Why are data labels overlapping?
Usually caused by:

Fix:

Avoid charting huge datasets directly.
Why does chart formatting reset?
Common reasons:

Avoid rebuilding source tables repeatedly.

Use secondary axis when needed.
Why are charts showing wrong dates?

Charts need real date values.
