XFUDGE

SUMMARY

Changes the x axis "fudge factor."

SYNTAX

XFUDGE {ON|OFF|v}

INPUT

{ON}:Turn fudge option on but don't change fudge factor.
OFF:Turn fudge option off.
v:Turn fudge option on and change fudge factor to v.

DEFAULT VALUES

XFUDGE 0.03

DESCRIPTION

When this option is on, the actual axis limits are changed by a "fudge factor". The algorithm for a linearly interpolated axis is:

XDIFF = XFUDGE*(XMAX-XMIN)
XMIN  = XMIN-XDIFF
XMAX  = XMAX+XDIFF

where XMIN and XMAX are the data extrema and XFUDGE is the fudge factor. The algorithm is similiar for logarithmically interpolated axes. The fudge option only applies when the axis limits are scaled to the data extrema (see XLIM.)
