[Bug] Automatic bar width with single X value too thin for range.

[lewisjb]

The width of a bar when there is only 1 X value is too thin in some cases because it doesn't take the xaxis range into account.

Example: http://codepen.io/anon/pen/rjWoyY

As you can see, the only difference between the two plots is one has a second trace, but the thickness of the bars on them is drastically different.

Thanks for the headsup.

What is the desired behavior in your mind?

In the meantime, note that in >v1.19.0 you can set the bar width, see example -> http://codepen.io/etpinard/pen/VPPvpM

@etpinard As I haven't looked at how it currently chooses the width, I wouldn't be able to give a desired behaviour that fits properly. I'm aware it's vague because it is an odd issue to fix, but thought I would put it here in-case somebody had a genius solution.

I did try manually setting the width, but ran into a different issue with it (which you can see in the issue referenced above)
