Price scale not displayed if first value is undefined

See original GitHub issue

Lightweight Charts Version: 3.7.0

Steps/code to reproduce: Display a chart with a dataset where the first value is missing.

[
    [ "2015", undefined ],
    [ "2016", "117000" ],
    [ "2018", "130000" ],
    [ "2019", "146100" ],
    [ "2020", "172900" ],
    [ "2021", "193900" ]
]

Actual behavior: The price scale for this series is not shown.

Expected behavior: The price scale for this series should try to pull axis information from the first-available value…and ultimately, should show the Y axis price scale.

From the first observation on your data:

the library doesn’t support this format of the data (like on your screenshot) so most likely this is not what you provide to the library (probably you have a post-processing of this result)
the library doesn’t accept undefined as a value for data. if you want to create a whitespace you need to omit value property
values MUST BE numbers, not strings

Probably it helps.
