scales

I need to set the bottom and left hand scale for the chart. I was thinking of setting the kilos scale to be the maximum weight + 10 kilos and the minimum to be the minimum weight minus 10. But motivationally, I think it may be better to see the weight scale go down to the weight where you are heading.
In addition to this, eventually, setting the target weight will mean the scale has to accommodate the targeted weight, and date.
All items should be available through the settings.
