`skipNull` is a configuration option, not a dataset field

[hraftery]

Documentation Is:

• Missing or needed?
• Confusing
• Not sure?

Please Explain in Detail...

skipNull is described at https://github.com/chartjs/Chart.js/blob/master/docs/charts/bar.md as a "Dataset Property".

Accordingly, I tried variations of chart.data.datasets[0].skipNull = true; and was never successful (nulls seem to be treated as zero). I've since enabled type checking and skipNull is reported as not a property of ChartDataSet.

I stumbled across this comment, which claims "skipNull is actually a controller option".

Sure enough, if I do something like:

const config: ChartConfiguration<'bar'> = {
    type: 'bar',
    options: {
      skipNull: true,
    },
  };

I have more success (no type error and nulls seem to be excluded, though I haven't tested thoroughly). So I suppose the documentation is out of date?

Your Proposal for Changes

I don't quite understand the page structure well enough to be sure, but I think some of the options in the "Dataset" section should be restricted to the "Options" section, so it doesn't look like they can be applied to a dataset. Maybe the "Options" section should more clearly explain the use of "ChartConfiguration"?
