Hi,

Thank you so much for a great library. Found a minor issue working with it, details below:

What is the current behavior?

Library cannot connectNulls when all values are nulls:

  { // works perfectly
    name: 'Page B',
    uv: 0, // this works, even if all other values are nulls/undefined/
  },

  { // doesn't work as expected
    name: 'Page B',
    uv: null,
    amt: undefined,
    // or omitted values
  },

What is the expected behavior?

Either null values show up as 0 visually and there's no tooltip or they connect existing data. Either sort of make sense, I guess.

Please provide a demo of the problem in a sandbox

Which versions of Recharts, and which browser / OS are affected by this issue? Did this work in previous versions of Recharts?

Didn't work in 3.6.0 or 3.7.0. MacOS, Chrome.
