Manage empty values

[mikael-s]

What would you like?
kuva could ignore missing or unusable values instead of failing to finish the plot.

Use case

Real series may have missing data. Or computer-generated data may contain values such as nan, inf, -inf.
In such cases, kuva will either fail with an error (absent data)

error: Row 2: cannot parse '' as a number

or will produce a partial/strange plot (the data is plot until nan is encountered, or only the axes are drawn with inf)

with a nan value

with the following data:

a,b
1,10
2,8
nan,6
5,4
6,nan

with an inf value

with the following data:

a,b
1,10
2,8
-inf,6
5,4
6,inf

Any prior art?

The plot could look like this, where the missing values would also be missing in the plot.

Hey,

This one is a bit tricky. Will need to handle the cases as they are ingested at runtime. I'll look at what data structures in rust can handle sparse data.

I'll get back to you on this one. But I agree it needs to be done.

Cheers,
