Code review comment for lp:~seb128/ubuntu-system-settings/battery-draw-x-text-1289460

I ran it (possibly with more data this time than last). There's a problem with the x coordinate for the previous day's data.

And do you know if it's possible to smooth the text? If you size that image to 100% you can see that the text is jagged and not very nice looking.
