Vertical padding

[jaimeiniesta]

Hi, thanks for sharing this awesome library!

Is there a way to use only vertical padding?

When using smoothing (even the default 0.15), the line can be cropped at the top and bottom borders:

This can be fixed by setting padding, but then I also get horizontal padding, it would be great to have only padding at the top and bottom.

Hi,

Thanks for the comment ;)

It's funny because I actually addressed that just a few hours ago. It's still a work in progress but here is the pr: #29.

These updates are expected to be included in the upcoming v0.3 version.

Awesome, thanks! I can confirm that the PR fixes that, here's the above charts with some vertical padding:

v0.3.0 has been released!

Please note that I made slight changes to the API compared to what you saw in the pull request.

# Both example are for padding top and bottom at 5, and left and right at 0.
# First version:
Sparkline_svg.new(data, padding: {5, 0})

# Current version:
Sparkline_svg.new(data, padding: [top: 5, left: 0, bottom: 5, right: 0])

Thanks! Just upgraded and everything looks smooth. I like the new syntax, much clearer 👍
