# xAxis.min

The minimum value of the axis. If `undefined`, the min value is automatically calculated.

If a datetime string is passed, it is parsed into epoch time according to the time zone given in time.timezone.

If the startOnTick option is true (default), the `min` value might be rounded down.

The automatically calculated minimum value is also affected by floor, softMin, minPadding, minRange as well as series.threshold and series.softThreshold.
