LineChart Y-Axis doesn't scale about termui

[gizak]

Hi @ryanbillingsley, this is due to LineChart' range keeps enlarging but not shrinking back when the given data is in smaller interval. So I guess in your case, you may have fed a small number (0 maybe) and the display range is stuck there.

This is actually a bug need to fix, and will fix soon. Let me know if this is not your case.

@gizak that data starts with the 40 - 60 interval, so the range isn't changing. It looks like the problem lies with this line in chart.go:

if lc.minY < lc.bottomValue {
    lc.bottomValue = lc.minY - 0.2*span
}

Because lc.bottomValue is not being set to anything, it will be 0, and always 0.

@ryanbillingsley, Hey you are right, it's not been initialized! Will fix it!
