These data sets are a list of settings for graphical parameters used by the Trellis Display functions. There are different settings depending upon the graphics device being used. The values have been selected to provide excellent displays on the selected device.

When a graphics device is started with the trellis.device function, the appropriate trellis.settings list is attached as an attribute to the .Device object in frame 0. All the Trellis functions try to get their graphical parameter settings from the list attached to the current .Device. If there is no trellis.settings attribute on .Device then the functions will use the values in the trellis.settings data set in the Trellis library.

The data set names and the graphics devices they are used with: trellis.settings - default list (for color device). trellis.settings.bw - default list (for black and white device). trellis.settings.bwps - postscript to a black and white printer. trellis.settings.color - SGI GL. trellis.settings.colorps - postscript to a color printer. trellis.settings.motif - motif (or openlook). trellis.settings.winbwps - win.printer to a black and white PostScript printer. trellis.settings.wincolorps - win.printer to a color PostScript printer. trellis.settings.wingraph - win.graph trellis.settings.winpcl - win.printer to a PCL (LaserJet) printer

These lists contain the following components, each itself a list whose components are named by graphical parameters and whose values give appropriate values of those parameters for the particular device. add.line add.text bar.fill box.3d box.dot box.rectangle box.umbrella cloud.3d dot.line dot.symbol pie.fill plot.line plot.symbol reference.line regions strip.background strip.shingle superpose.line superpose.symbol wires
