cpdset current plotting device
Set current plot device. The same can be achieved with the setplot device command, which takes the same options. In XSPEC12 as in previous versions, the plot device options are those allowed by the PGPLOT library.
When plotting to the screen, the most commonly used devices are/xs (/xserve) and/xw (/xwindow). If you select/xs, the plot window is persistent: it remains visible and in the selected position even after the XSPEC session is finished. With/xw the plot window closes at the end of the XSPEC session. Also note that on some platforms, when using/xs in multiple desktops, you might not see the window appear in a second desktop if it is still open in the first.
If the second argument does not start with a ’/’ character, which indicates that the string represents a PGPLOT device, it is taken to be a filename for Postscript output, and the default postscript driver will be used. The default postscript driver produces a monochrome plot in landscape orientation.
The filename argument can be followed by a ’/’ that specifies a particular postscript driver variant. Allowable variants are: cps (color postscript), vps (monochrome portrait orientation), and vcps (color portrait orientation), as well as the default, ps.
PGPLOT devices
A number of plot device types are supported in XSPEC. PGPLOT devices available on Unix machines are:
cpd none closes the device. For Postscript output, it flushes the write buffer into the file and closes the file. Note that in XSPEC12, each plot command produces a separate page in the postscript file, unlike previously where each plot overwrote the previous plot.
Examples:
Produce a set of color postscript plots in landscape orientation
// ... commands to produce a plot. XSPEC12> cpd dataplot.ps/cps XSPEC12> plot data chi XSPEC12> plot ufspec XSPEC12> plot efficiency XSPEC12> cpd noneWill produce 3 plots in the file dataplot.ps
Note, in contrast, that the hardcopy command will print only the plot that is currently in a graphics frame.
