in this mock, it would be great to see some data in the next visible range, like after 9am the next day, just to capture some of the tick labelling etc

Good point. I added another mock in 8a4bae3.
And we are going to revise tick behaviour (including these mocks) in #4734 after this PR is merged.

Oh interesting, I wouldn't have guessed that the problem traced back to distinctVals, nice find!

TIL:

all undefined elements are sorted to the end of the array, with no call to compareFunction

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort

So perhaps all we need is the loop to find last and the rest of this can stay as it was, as we'll never have undefined anywhere else after a sort?

maybe worth testing this in IE before relying on it. I've confirmed in Chrome, FF, Safari on my mac so seems robust on modern browsers.

If it were to fail on IE, I wouldn't trust that sorting works at all then with interspersed undefined values, and better would be to filter these out before even starting (instead of the slice() call)

maybe worth testing this in IE before relying on it. I've confirmed in Chrome, FF, Safari on my mac so seems robust on modern browsers.

If it were to fail on IE, I wouldn't trust that sorting works at all then with interspersed undefined values, and better would be to filter these out before even starting (instead of the slice() call)

Also we should possibly addess #4818 in this PR which seems related to applying distinctVals.

The heatmap bug is not related to distinctVals at all. So we are not going to fix that in this PR.

Oh interesting, I wouldn't have guessed that the problem traced back to distinctVals, nice find!

TIL:

all undefined elements are sorted to the end of the array, with no call to compareFunction

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort

So perhaps all we need is the loop to find last and the rest of this can stay as it was, as we'll never have undefined anywhere else after a sort?
