The chop parameter allows to control the labels' position on tick marks: However, for vertical axis, they are right adjusted. However if the axis is vertical then are drawn perpendicular to the axis.īy default axis labels are centered on tick marks. The distance between the labels and the axis body can be changed with SetLabelOffset.īy default axis labels are drawn parallel to the axis.
However the option "=" allows to draw them on the same side.
Labels are normally drawn on side opposite to tick marks. gStyle->SetTickLength(0.02,"x") set the tick length for the X axis of all histograms drawn after this instruction.Ī good way to remove tick marks on an axis is to set the tick length to 0: h->GetXaxis()->SetTickLength(0.).h->GetXaxis()->SetTickLength(0.02) set the tick length for the X axis.When plotting an histogram h the tick marks size can be changed using: 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. chopt = "U": Unlabelled axis, default is labeled.īy default, tick marks have a length equal to 3 per cent of the axis length.chopt = "+-": tick marks are drawn on both sides of the axis.chopt ="-": tick mark are drawn on the negative side.chopt = "+": tick marks are drawn on Positive side.
The chop parameter allows to control the tick marks orientation: By default tick marks are drawn on the positive side of the axis, except for vertical axis for which the default is negative.
