Enhanced version of sprucegum's legend feature for line charts

[luebbert42]

Hi,

I needed this feature as well, but figured out that there is an issue with longer titles (they were not positioned correctly each under another, so I fixed this (*)).

I also moved the drawLegend function to the linechart class and added an option to set the text for the legend. Legends are off by default.

How can I use this feature? enable the legend with: drawlegend: true, legend_title: "My Legend", // fallback is "Legend: "

Regards Dorthe

(*) Pls be patient with me, this is my first pull request on github, I hope I did everything in a correct way, it's a bit spooky ;-)

Hi Luebbert42! Cool! I'm quite busy right now so it might be a couple of days before I can look into this, but I'll get around to it :)

Hi Kilian,

most probably I will modify this feature again (I need an option to set the legend in another corner of the chart). I'll keep you up to date.
