Set labels' font.

Definition at line 183 of file TAttAxis.cxx.

◆ SetLabelOffset()

Definition at line 204 of file TAttAxis.cxx.

◆ SetMaxDigits()

void TAttAxis::SetMaxDigits ( Int_t maxDigits = 5 )

virtual

This function sets the maximum number of digits permitted for the axis labels above which the notation with 10^N is used.

For example, to accept 6 digits number like 900000 on the X axis of the histogram h call:

h->GetXaxis()->SetMaxDigits(6);

The default value is 5.

The default value for all axis can be set with the static function TGaxis::SetMaxDigits.

Definition at line 264 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.

Definition at line 229 of file TAttAxis.cxx.

◆ SetNdivisions() [2/2]

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

virtual

◆ SetTitleColor()

void TAttAxis::SetTitleColor ( Color_t color = 1 )

virtual

Set color of axis title.

Definition at line 313 of file TAttAxis.cxx.

◆ SetTitleFont()

void TAttAxis::SetTitleFont ( Style_t font = 62 )

virtual

Set the title font.

Definition at line 322 of file TAttAxis.cxx.

◆ 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 standard position that is computed in function of the label offset and size.
offset = 1.2 will add 20 per cent more to the standard offset.
offset = 0 automatic placement for the Y axis title (default).

Definition at line 294 of file TAttAxis.cxx.

◆ SetTitleSize()

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.
