I can investigate this one!

Go for it! I think the trouble comes from https://github.com/chartjs/Chart.js/blob/master/src/scales/scale.logarithmic.js#L31

[Jareechang]

@etimberg 👌, it seems like the max and min are not finite when the dataset are hidden.

It seems to fix things when I make a change on https://github.com/chartjs/Chart.js/blob/master/src/scales/scale.linear.js#L28-L29

should I still implement check for finite values for other scales ?

anyways, PR is on the way.

I would check the logarithmic scale and see if it has the same issue. Please include a test with all datasets hidden to make sure this doesn't break in the future
