Line going off the top of chart

[Boldonglen]

I have an issue where the data on my line chart is going beyond the top of the chart.

The below CodePen shows what I mean.

Okay so after a bit more investigation it seems like its because the yaxis doesnt like decimal numbers. If I change the highest value in my array (4.791986999999999) to 5 it does not go off the top.

Not only this but if I set the max value of the yaxis to be a decimal (in my case i tried to set it to my max value in the array (4.791986999999999) it still doesnt work, guessing because the chart doesnt like the decimal value?

The chart loves decimal values 😀, and care is taken to allow decimal values to be printed precisely.
Maybe I missed some checks, I will take a look soon.
