invisible date bar

[tjinaton]

When i have bar-graph with date-axis and custom range specified the bar becomes invisible when there is only 1 bar.

2-bars:

Turns out the bar is very small. Which can be seen when the range becomes small.
Workaround: Set width on bar: 1 unit seems to be 1ms.

It would be nice if the bar gets a better width.

duplicate of #1346, feel free to weigh in over there. I doubt we'll change this behavior though - we could pick some other value but it would usually be wrong. I'd recommend setting width explicitly (yes, in milliseconds) https://codepen.io/alexcjohnson/pen/YgYqMW
