Hi, I think the graph tracker is excellent, especially considering it is a free service!
But one improvement I think it desperately needs is a better way of representing the numbers on the x-axis of the graph i.e. the weight.
It is difficult to see what a line actually represents. To clarify what I mean, its not obvious if a dot on the graph means 14, 15 or something in between like 14.5.
Its not just me being stupid, I asked friends and family for their opinions too and they agree with me.
What do you guys think?
