Weight graph

Kind of nitpicky, but ...

When I graph my weight, the x axis starts at 0, so  the movement across the y axis doesn't show a lot of detail, if that makes sense ... the line is almost level.  If the x axis started at, say, my weight minus 10 pounds, the graph would show more.

Okay - actually - now another problem - I wanted to paste in a graph to show what I was talking about, and now I can't even get the correct date range to work.  No matter how and how many times I put 1/1/2013 - 9/17/2013 it comes back with a weird date range.  (still, you can see what I was originally referencing .. the graph lives completely on the top of the graph):
