Only if the Y-axis originates at 0.
The normal level could be 500, rising to 504 for pancake day.
The lesson is, always label your graphs or else it'll start pedantic conversations in your thread.

I was always taught that a graph always has to start from zero
and if you were going to start from another value due to scaling (lack of points at lower values) you would need to include a squiggly line not unlike a sawtooth wave on the axis.

You can do.
So long as you label it properly it's not really necessary.
There's no point in starting from zero if your interested in a small region that's nowhere near it, you may as well zoom into the important bit.
