General Information

Editing

  • Beware: there is no Undo option but Reverse to saved so it is better to often save your working document.
  • copy-paste within different boxes does not seem to be possible, one can open a terminal for temporary paste.

Customizing Xmgrace

General parametrization of the software

create the file ~/.grace/gracerc.user and enter your device parameters.

Example : setting default printing to the .eps format : add the following line

HARDCOPY DEVICE "EPS"

Creating a default template graph used when opening xmgrace

A simple way to customize Xmgrace is to use a default template .agr file that you can save in the directory (create it if it does not exist)

~/.grace/templates/Default.agr

Changing colors in Xmgrace

The color maps in a ".agr" file are defined at the beginning using the following syntaxe

@map color number to (R,G,B), "colorname"

where R,G,B and the usual integers from 0 to 255 of the RGB code.

It is highly recommended not to change the first two colors (black&white) as they are used as default parameters in many places. Keep

@map color 0 to (255, 255, 255), "white"
@map color 1 to (0, 0, 0), "black"

For others, you can add/change colors and colornames. The color number matters when you use set different colors for instance.

Manipulating data

Useful inline commands and aliases

  • grabbing data from pipe
:> ./program_printing_data | xmgrace -pipe
  • Some bash aliases (or command lines) for defining axis and data type
alias xmlog='xmgrace -log xy'
alias xmlogy='xmgrace -log y'
alias xmlogx='xmgrace -log x'
alias xmbar='xmgrace -settype xydy'
alias xmlogbar='xmgrace -log xy -settype xydy'
alias xmlogybar='xmgrace -log y -settype xydy'

Typography

  • when typing in a text , you can invoke the Font-Tool application by pressing
