Introduction to Grace graphing program
This is a brief introduction to Grace, a useful and free graphing package. Grace works well on nearly any Unix/Linux-like platform; in principle it can be run under Windows (although I have not tried this myself). For more information go to the Grace web site, http://plasma-gate.weizmann.ac.il/Grace/
Also see the Grace manual http://plasma-gate.weizmann.ac.il/Grace/doc/UsersGuide.html or (new) the Grace tutorial http://plasma-gate.weizmann.ac.il/Grace/doc/Tutorial.html
Grace is difficult to run remotely, unless you set up X-windows properly. Grace is setup on the computers in the computational lab.
To run Grace on the computational lab computers (on the Linux drive)
To read in a file
Click Data --> Import --> Ascii
Choose file ( .dat is default type) and click Okay
To manipulate the presentation of the data (e.g., change color, use dashed lines, etc.)
Click Plot --> Set appearances
To manipulate the axes
Click Plot --> Axis properties
To change from linear to log see "Scale"
You can also change the range of the axis, the spacing of tick marks, etc.
To save graph
Click File --> Save (you'll have to enter a name)
To write out graph as a postscript file
Click File --> Print setup...
Choose PostScript or EPS as Device
Click on button "Print to file"
Click on Apply then Close
Go back... click File --> Print
