v3 - normalized option not working when dataset begins with null values

[benmccann]

Expected Behavior

I should be able to have a dataset which skips the first points

Current Behavior

The chart is misaligned and missing the ending points when normalized: true and the dataset starts with null values

Possible Solution

The issue seems to be coming from here:

Chart.js/src/core/core.datasetController.js

Line 569 in 7c75310

return (!isFinite(value) || !isFinite(otherValue) || otherMin > otherValue || otherMax < otherValue);

I'm not sure if we should ever be checking otherValue, but perhaps we at least don't need to check it if normalized: true?

Steps to Reproduce

If you set normalized: false the chart is drawn as expected

Context

I was trying to draw a chart and it took me awhile to figure out that might dataset wasn't missing values since the end was being cut off

Environment
