option to reverse the direction of the legend

[curran]

I ran into this too. Here's an example where I ended up jumping through hoops to get the color legend and visualization to be ordered in the same way http://bl.ocks.org/curran/805413fb3b2efaada1ce

I ended up reversing the order of the stacked bars with this nasty line of code, so the order is the same on the color legend and the visualization.

Thank you, curran! Your code and idea are actually very neat. During the weekend I'll try to apply the idea to my situation. Maybe I just have to reverse both the domain and range of my scale...

Thanks! It is a bit tricky. I agree that it would be cool to think about
maybe adding an option to the legend to reverse it, without the need to
change around the scale.

Yes, reversing both the domain and the range works. (I take the opportunity to multiply the numbers by 100 at the same time, making percent values out of ratios.)

My problem is solved so I wouldn't mind if susielu closes this issue.
(At the same time I feel the same as curran.)

Apologies on the late reply. There is actually an option called ascending that you can change to true if you want to reverse the order. It was added from a pull request and I forgot to add that feature to the documentation, will add that today.

Nice! Thank you.

OK I tried it just now. One can just do this: .ascending(true) to achieve this effect.
You might want to add an example and a brief description in the doc.

But before adding an example, you might consider changing its name.
I would probably call it .descending(true) instead.
Or better, .reverse(true) considering both vertical and horizontal legends.
This change may not hurt if not too many people are using it yet.
Name changes or not, this already makes my code look clearer. Thanks!
