The following global variables are associated with and govern some aspects of a plot:
a scaling factor for the size of the dashes in the plot lines. Defaults to 1.
The number of minor tick marks per major (labeled) tick mark on the x and y axes if these are linear axes.
Determines the font to use for the plot labels. Defaults to 3 (roman sans serif).
If set to zero, then make the x (
!fzx) and y (
start not higher than at 0 – unless appropriate explicit plot limits
are set through
!fz defaults to
If set to zero, then the data value range per major tick mark is
determined automatically; otherwise, it is taken from
If unequal to
0, then labels are drawn along the x and y axes.
These default to
!mxb, !mxt, !myb, !myt
The data values that correspond to the edges of the last drawn plot: the
x axis ranged between
!mxt, and the y axis
Determines whether the plot axes are linear or logarithmic, and whether
a full plot box is drawn or only an x and an y axis. If
mod 4 is equal to
0, then a linear-linear plot is drawn;
1 yields a linear x - logarithmic y plot;
2 gives a
logarithmic x - linear y plot; and
3 provides a
logarithmic-logarithmic plot. If
!pltyp is less than 4, then a
full plot box is drawn. If
!pltyp is greater than 3, then only
the x and y axes are drawn.
Determine the size of the vertical (
!plxerrb) and horizontal
!plyerrb) error bars, in
If these are set unequal to
0, and if the plot limits are
determined from the data values, then some extra room is left between
the corresponding plot edges and the nearest data points. They default
The data values that correspond to the first labeled tick mark on the x and y axes. If a particular axis was logarithmic, then the corresponding variable is a logarithm to base 10.
The data values that correspond to the interval between labeled tick marks on the x and y axes. If a particular axis was logarithmic, then the corresponding variable is a logarithm to base 10.
The size of the major tick marks, in
dvi coordinates. Positive
sizes correspond to tick marks pointing into the plot, negative values
correspond to tick marks pointing out of the plot. They default to
The size of the minor tick marks, relative to the corrsponding major
tick marks. They default to
!wxb, !wxt, !wyb, !wyt
The coordinates of the edges of the plot window, measured in
coordinates. The lower left-hand corner of the plot window is at
(!wxb,!wyb) and the upper right-hand corner at
