//
// _Input parameters:
//
// xmin : X origin coordinate in WC space.
// xmax : X end axis coordinate in WC space.
// ymin : Y origin coordinate in WC space.
// ymax : Y end axis coordinate in WC space.
// wmin : Lowest value for the tick mark
// labels written on the axis.
// wmax : Highest value for the tick mark labels
// written on the axis.
// ndiv : Number of divisions.
//
// ndiv=N1 + 100*N2 + 10000*N3
// N1=number of 1st divisions.
// N2=number of 2nd divisions.
// N3=number of 3rd divisions.
// e.g.:
// nndi=0 --> no tick marks.
// nndi=2 --> 2 divisions, one tick mark in the middle
// of the axis.
//
// chopt : options (see below).
//
// chopt='G': loGarithmic scale, default is linear.
// chopt='B': Blank axis. Useful to superpose axis.
//
// Orientation of tick marks on axis.
// ----------------------------------
//
// Tick marks are normally drawn on the positive side of the axis,
// however, if x0=x1, then negative.
//
// chopt='+': tick marks are drawn on Positive side. (default)
// chopt='-': tick mark are drawn on the negative side.
// i.e: '+-' --> tick marks are drawn on both sides of the axis.
// chopt='U': Unlabeled axis, default is labeled.
//
// Size of tick marks
// ------------------
// By default, tick marks have a length equal to 3 per cent of the
// axis length.
// When the option "S" is specified, the length of the tick marks
// is equal to fTickSize*axis_length, where fTickSize may be set
// via TGaxis::SetTickSize.
//
// Position of labels on axis.
// ---------------------------
//
// Labels are normally drawn on side opposite to tick marks.
// However:
//
// chopt='=': on Equal side
//
// Orientation of labels on axis.
// ------------------------------
//
// Labels are normally drawn parallel to the axis.
// However if x0=x1, then Orthogonal
// if y0=Y1, then Parallel
//
// Position of labels on tick marks.
// ---------------------------------
//
// Labels are centered on tick marks.
// However , if x0=x1, then they are right adjusted.
//
// chopt='R': labels are Right adjusted on tick mark.
// (default is centered)
// chopt='L': labels are Left adjusted on tick mark.
// chopt='C': labels are Centered on tick mark.
// chopt='M': In the Middle of the divisions.
//
// Format of labels.
// -----------------
//
// Blank characters are stripped, and then the
// label is correctly aligned. the dot, if last
// character of the string, is also stripped,
// unless the option "." (a dot, or period) is specified.
// if SetDecimals(kTRUE) has been called (bit TAxis::kDecimals set).
// all labels have the same number of decimals after the "."
// The same is true if gStyle->SetStripDecimals(kFALSE) has been called.
//
// In the following, we have some parameters, like
// tick marks length and characters height (in percentage
// of the length of the axis (WC))
// The default values are as follows:
//
// Primary tick marks: 3.0 %
// Secondary tick marks: 1.5 %
// Third order tick marks: .75 %
// Characters height for labels: 4%
//
// Labels offset: 1.0 %
//
// optional grid.
// --------------
//
// chopt='W': cross-Wire
// In case of a log axis, the grid is only drawn for the primary tick marks
// if the number of secondary and tertiary divisions is 0.
//
// Axis bining optimization.
// -------------------------
//
// By default the axis bining is optimized .
//
// chopt='N': No bining optimization
// chopt='I': Integer labelling
//
// Maximum Number of Digits for the axis labels
// --------------------------------------------
// See the static function TGaxis::SetMaxDigits
//
// Time representation.
// --------------------
//
// Axis labels may be considered as times, plotted in a defined time format.
// The format is set with SetTimeFormat().
// wmin and wmax are considered as two time values in seconds.
// The time axis will be spread around the time offset value (set with
// SetTimeOffset() ). Actually it will go from TimeOffset+wmin to
// TimeOffset+wmax.
// see examples in tutorials timeonaxis.C and timeonaxis2.C
//
// chopt='t': Plot times with a defined format instead of values
