   void setAxisMinimum(float min)

  Set a custom minimum value for this axis. If set, this value will not be calculatedautomatically depending onthe provided data. Use resetAxisMinValue() to undo this. Do not forget to callsetStartAtZero(false) if you usethis method. Otherwise, the axis-minimum value will still be forced to 0.

• setAxisMinValue

  Use setAxisMinimum(...) instead.

• setAxisMaximum

   void setAxisMaximum(float max)

  Set a custom maximum value for this axis. If set, this value will not be calculatedautomatically depending onthe provided data. Use resetAxisMaxValue() to undo this.

• setAxisMaxValue

  @Deprecated() void setAxisMaxValue(float max)

  Use setAxisMaximum(...) instead.

• calculate
