Support for line width/color array?

See original GitHub issue

If there are multiple paths in a single trace (separated by null(s)), it could be useful to have a different stroke-width for each path. This way, I could solve this issue, without having to draw a separate trace for each line.

Minimal example here – http://codepen.io/cpsievert/pen/wMzdME

In addition to https://plot.ly/r/reference/#scatter-line-width accepting a data array, it’d also be useful to have https://plot.ly/r/reference/#scatter-line-color accept a data array, so I can convert a plot like this:

qplot(data = economics, x = date, y = unemploy, colour = unemploy, geom = "line")

rplot

@etpinard, Re:

I’m not 100% convinced this is worth implementing.

One reasonable and potentially important application for varied line style (both width and color) is the network graph (https://plot.ly/python/network-graphs/).

The common use case is to use the line width and/or color to represent the weight of the connection, see e.g. this plot.
