in case of having the following data:

data: [-1.5, 1 - 0, 2 - 5, -1.5, 100, 5, -2.3]

with gridLineLabelPrecision: 3:

with gridLineLabelPrecision: 2:

after digging through the codebase, I discovered that this is not this package's fault, but it's a usage of the wrong function.

this package uses toStringAsPrecision on the values, which evaluates the following values like:

→   100.0.toStringAsPrecision(3)
    "100"
→   100.0.toStringAsPrecision(2)
    "1.0e+2"

I suggest adding a gridLineLabelFixed parameter, which would apply toStringAsFixed on the supplied data
