Save axis attributes as C++ statement(s) on output stream out.

Reimplemented in TAxis.

Definition at line 111 of file TAttAxis.cxx.

◆ SetAxisColor()

void TAttAxis::SetAxisColor ( Color_t  color = 1,
Float_t  alpha = 1. 
)
virtual

Set color of the line axis and tick marks.

Definition at line 163 of file TAttAxis.cxx.

◆ SetLabelColor()

Float_t  alpha = 1. 
)
virtual

Set color of labels.

Definition at line 173 of file TAttAxis.cxx.

◆ SetLabelFont()

void TAttAxis::SetLabelFont ( Style_t  font = 62)
virtual

Set labels' font.

Definition at line 183 of file TAttAxis.cxx.

◆ SetLabelOffset()

void TAttAxis::SetLabelOffset ( Float_t  offset = 0.005)
virtual

Definition at line 193 of file TAttAxis.cxx.

◆ SetLabelSize()

void TAttAxis::SetLabelSize ( Float_t  size = 0.04)
virtual

Set size of axis labels The size is expressed in per cent of the pad width.

Definition at line 204 of file TAttAxis.cxx.

◆ SetNdivisions() [1/2]

void TAttAxis::SetNdivisions ( Int_t  n = 510,
Bool_t  optim = kTRUE 
)
virtual

Set the number of divisions for this axis.

  • if optim = kTRUE (default), the number of divisions will be optimized around the specified value.
  • if optim = kFALSE, or n < 0, the axis will be forced to use exactly n divisions.
    n = n1 + 100*n2 + 10000*n3
    Where n1 is the number of primary divisions, n2 is the number of second order divisions and n3 is the number of third order divisions.

e.g. 512 means 12 primary and 5 secondary divisions.

If the number of divisions is "optimized" (see above) n1, n2, n3 are maximum values.

◆ SetNdivisions() [2/2]

void TAttAxis::SetNdivisions ( Int_t  n1,
Int_t  n2,
Int_t  n3,
Bool_t  optim = kTRUE

◆ SetTitleOffset()

void TAttAxis::SetTitleOffset ( Float_t  offset = 1)
virtual

Set distance between the axis and the axis title Offset is a correction factor with respect to the "standard" value.

  • offset = 1 uses the default position that is computed in function of the label offset and size.
  • offset = 1.2 will add 20 per cent more to the default offset.

Definition at line 262 of file TAttAxis.cxx.

void TAttAxis::SetTitleSize ( Float_t  size = 0.04)
virtual

Set size of axis title The size is expressed in per cent of the pad width.
