Have an option to make the tooltip align floating points (or at least align right)

[kanitw]

Currently it's a bit hard to compare.

[kanitw]

We may also want to consider using a monospace font for numbers to facilitate alignment.

[domoritz]

I agree! Ideally we align to the decimal point.

I don't know whether we have a way of knowing whether something is a number since we don't format them. It's all coming from Vega.

[kanitw]

I think we can try to convert to number. If something is a number, then we won't get NaN. :)

[domoritz]

wouldn't we throw away formatting like trailing 0s?

[kanitw]

We can just do the conversion just to check if something is a number. Then align the dots in floating points in real time since there won't be that many variables to show on a tooltip anyway.

[domoritz]

What if the locale dictates , instead of . to separate the non-fraction from the fraction part?

[kanitw]

That's a bug that a German should fix. :p

[kanitw]

Joke aside I'm sure one can read the locale and adjust the delimiter

[domoritz]

Jep, just wanted to make sure we think through the potential problems.

[domoritz]

We should also make sure numbers have the same width. See https://medium.com/mission-log/design-better-data-tables-430a30a00d8c (e.g. with font-variant-numeric: lining-nums tabular-nums;).
