Freud User Manual
Open dataset in file datasetFile. Returns number to be used when creating instantiations.
Example:
fropen testh.cdf3
Create a map instantiation using the specified defaults file.
frxy [defaultsFile]
Create a xy background instantiation using the specified defaults file.
frcontour datasetNumber sliceExpression [defaultsFile]
Create a contour instantiation using the specified dataset number (returned from the fropen command) and using the variable specified by the sliceExpression. Optionally load defaultsFile.
Example:
frcontour 1 "Z(frtime=3,level=2)"frvector datasetNumber1 sliceExpression1 datasetNumber2 sliceExpression2 [[defaultsFile]
Create a vector instantiation using the specified dataset numbers (returned from the fropen command) and using the variables specified by the sliceExpressions.
Example:
frvector 1 "u(time=2)" 1 "v(time=2)"
frprint printer lp3Print on printer lp3
frprint file test.psSend the plot output to file test.ps
Set the page orientation to orientation (either portrait or landscape), and/or set the active viewport to num.

If getactive is specified, the currently active viewport is used. If this viewport contains a plot, an error will result if the size or fwidth keywords are used.
If getactive is not specified, a new viewport is created and becomes the active viewport.
The viewport can be deleting by means of the frdelete command.
frviewport v getactive size {4 4 6 6}
Set the coordinates of the active viewport to be (4,4)"->(6,6)"
frviewport v size {0.25 0.25 8.25 4.25} fwidth 0.9
Create a new viewport with handle v that has a plot frame width of 0.9 and is bounded by the coordinates (0.25, 0.25)"->(8.25,4.25)"
