XLOGGRAPH (CCP4: Deprecated Program)


xloggraph - X-windows tool, a viewer of specially formatted `log' files.


xloggraph logfilename


xloggraph belongs to the XCCPJiffy class of simple X11 graphic based programs. xloggraph reads specially formatted log file produced by some of the CCP4 programs, recognises tables and graphs described in it and produces their graphic representation.
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:

to exit the program
box containing current log file name
Show Table List
Clicking here returns to complete list of Tables in the file. This box is sensitive only if the index to Graphs is displayed.
View File
Allows one to scroll through the log file (Try CTRL/S when the pointer is in text window)
Select from Tables
Select from Graphs
A list of the Tables/Graphs stored within the log file. Clicking on the particular Table name will create an index of the Graphs available from that particular table Clicking on the particular Graph name will generate a Graph in an X-window.
Quit - in that window closes the window
Plot - creates a PostScript version. (If you want a file go to the Control Panel first.)
Control Panel
Clicking Left Mouse button here allows one to Toggle between Portrait and Landscape for the output Postscript file conversion and the option to specify a Output File for the Postscript file. The print command is controlled by the XCCPJiffy*psPlotCommand resource. The Quit button exits the control panel.


The sections on the syntax for graphs, text, keytext and summaries can be found in a separate document on the loggraph format.

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:

XCCPJiffy.graph*draw2d.background:              white
XCCPJiffy.graph*draw2d.pen1Color:               black
XCCPJiffy.graph*draw2d.pen1LineWidth:           1
XCCPJiffy.graph*draw2d.pen10Color:              indigo
XCCPJiffy.graph*draw2d.pen10LineWidth:          1

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
