fit data graph y axis

sometimes the fit data, as viewed on the phone's connect app, shows an origin of 0, while sometimes it uses something closer to the lower bound... is there any way to set the graph's extents?  how does connect choose the graph's y axis?

here's an example - the two data fields (of the same name) are the same as far as posting fit data, however timing is different so the data differs slightly.

  • any advice for this? note in the original post picture the top graph y starts at 53 and in the bottom graph y starts at 0, but the data used for both graphs should essentially be the same except possibly slight timing differences.  i'm wondering how do i get it so it always starts at a reasonable # (like 53) instead of 0...
