Increase axis autorange when bars have outside text labels by emilykl · Pull Request #7675 · plotly/plotly.js

Adds a step during bar calc to add extra padding to axis range if bar has outside text labels.

This is a stopgap fix for the fact that text labels are not taken into account during autorange calculations (see #2000).

Unfortunately, as discussed in that issue, modifying autorange to account for text labels is a significant amount of work, so I've opted for a more limited fix to address the issue identified in #2001.

You can also load the hist_stacked mock in the devtools as another test case.
