Hi! Thanks for this very cool library!

My goal is to plot a DataFrame which represents a time series.

I'd like to use these encoding channels in my plot:

• x channel is the period column,
• y channel is the value column,
• color channel is the series_code column.

I'm wondering if the line plot isn't missing a c= keyword, like the scatter plot.

What do you think about it?

That's tricky, because pdvega aims to follow the Pandas plotting API, which doesn't support that.

The way to do that in the current API is something like this:

data.pivot_table(index='period', columns='series_code', values='value').vgplot.line()

(There may be some typos there, but you get the idea)
