Remove unnecessary autoscale handling in hist().

anntzer · anntzer · commit ddaf96d2439b · 2020-09-12T16:35:05.000+02:00
Temporarily disabling autoscale is unnecessary now that we have lazy
autoscaling.  The call the _request_autoscale_view() is already issued
by the underlying calls to `bar()` or `fill()`.
