Based on description of tight ("If True, set view limits to data limits"), I would have expected MPL 1.5.1 behavior (see code and image below). Though perhaps there was a little margin added intentionally?

Edit: I see this first part was intended, as change#5583. See second issue below.

import matplotlib as mplplt.plot([1,2,3,4])plt.autoscale(axis='both', tight=True)plt.show()

Aside from this, MPL 1.x use to conveniently adjust view limits for log and symlog when tight autoscaling was not on, but MPL 2 does not seem to do this anymore.

This actually also looks like a result of#5583. I would argue the previous behavior was actually desirable in many instances. Is there a way to recover it?

import matplotlib as mplplt.plot([1,2,3,4])ax = plt.gca()ax.set_xscale('log')ax.set_yscale('log')plt.show()
