It's marked private but not since the beginning (introduced in v2.6 and made private in v2.7) so not sure it's a good idea to rename it since it doesn't add any benefit.

Though, good point from @kurkle that the returned value isn't anymore the label width for vertical scales. Introducing _getLabelSize (private) returning {w, h} and have getLabelWidth deprecated and be return _getLabelSize().w instead seems a good alternative?

I want to know how @kurkle got time travel abilities :-)

Another thing noticed here is that offset is not accounted for in chartArea. Box size is calculated from chartArea in that example, that's why it looks so wrong in master.

For 2.8.0 this can be worked around by setting maxRotation: 90 on vertical time scale.

If we take into account offset, the code would look like this?

var capacity = Math.floor(me.isHorizontal() ? me.width / size.w : me.height / size.h);

if (me.options.offset) {
    capacity--;
}

return capacity > 0 ? capacity : 1;

@nagix I think you are right. I'll test that when I have a chance.

Made @nagix suggestion and then realized its not strictly correct either. If min/max is defined, offset is ignored at that end. Doesn't make a huge difference though.

Ok, this is related to #5618. If everyone agrees that offset should work even when min or max is set, it should be fixed separately.
