XLOGGRAPH (CCP4: Deprecated Program)
- X-windows tool, a viewer of specially formatted `log' files.
xloggraph belongs to the XCCPJiffy class of simple X11 graphic based
xloggraph reads specially formatted log file produced by
some of the CCP4 programs, recognises tables and
graphs described in it and produces their graphic
NB: the loggraph program offers an
alternative to xloggraph.
xloggraph uses an X-window device and has an option to create a PostScript file.
Running the program xloggraph creates a Header window with boxes showing:

REMARK FOR APPLICATION PROGRAMMERS
The sections on the syntax for graphs, text, keytext and summaries
can be found in a separate document on the
NOTE ON COLOURS AND LINE STYLES - For Users and Programmers
xloggraph works in pen graphic mode, each object is painted by a
different virtual pen. By definition, xloggraph uses pen1 for
Graph axes and texts, pen2 for 1st graph, pen3 for the second
etc. Currently 10 pens are available.
Colour, Line width and Postscript properties of virtual pens are
controlled via the entries in X-resource database (see X manual). It
is recommended to load X-resources into the X-server database (xrdb).
Once the database is loaded, one can optimise it using xrdb to
load/merge a personalised set of X-Application Resources.
X pen is controlled by:
Postscript pen by:
XCCPJiffy*psPen1Attr: 1 setlinejoin 0.5 setlinewidth  0 setdash
XCCPJiffy*psPen10Attr: 1 setlinejoin 0.9 setlinewidth [8 2] 0 setdash
To check your current setting use for instance
xrdb -query | grep XCCPJiffy | more
loggraph, X (1), xccpjiffy2idraw (1), xrdb (1)
DISPLAY to figure out which display to use.
