Hours to Show parameter not enforced

Version 0.2.1

Using these parameters:

          hours_to_show: 2
          points_per_hour: 3

produces this graph:

where there are actually 6 hours in display, with one point shown per hour.

Testing different value combinations is showing that the “real” number of hours that are shown is actually = hours_to_show * points_per_hour.

Increasing points_per_hour to 6, produces a graph that spans for 12 hours, even if it was supposed to be showing 2 hours. It’s a very strange behavior 😃

In addition, using a number < 1 for “hours to show” proudces a weird result (apparently showing an entire week or so of ‘hours’).

There is also a problem with the labels (too much to the left and also too tiny after reducing font_size to 60) but I think there is a merged patch that would fix that in master already

Tested - all issues fixed and it looks really great What an outstanding addition to HA. Thanks @kalkih for this
