get_style, landscape, systems, legends, clegends
get the detailed style of the current drawing. The arguments
are all outputs:
landscape: 1 if drawing is landscape orientation, 0 if portrait
system: an array of GfakeSystem struct instances, one per
coordinate system in this drawing (ordinarily just one).
legends: a GeLegendBox structure instance describing the layout
of the plot legends
clegends: a GeLegendBox structure instance describing the layout
of the contour legends
See the help for the GeLegendBox and GpTextAttribs structs for
the details of the legends and clegends arguments. Basically,
you can adjust the location of the legends on the page, the
font and height of the characters used to render legends, and
whether the legends are split into two columns.
The coordinate systems are the systems accessible via the
plsys command. The index of the system in the system array is
the index you use to switch to it in the plsys command. Simple
styles have only one coordinate system, and you should carefully
consider whether you should design a graphic style with multiple
coordinate systems -- most likely, you can do a better job by
combining several separate Yorick pictures with some sort of
page layout program, rather than trying to do this work within
Yorick itself.
See the help for the GfakeSystem struct for complete details of
what you can adjust. The most interesting features you can
control are the location and aspect ratio of the viewport, and
the details of the axis ticks and labels. The gridxy function
provides a simpler interface for fiddling with ticks and labels
if that is all you need. The system.viewport member is the
[xmin,xmax,ymin,ymax] of the rectangle on the page where your
plots will appear, expressed in NDC coordinates (0.0013 NDC units
equals one point, and there are 72.27 points per inch, and 2.54
cm per inch; the NDC origin is always at the lower left hand
corner of the paper, with x increasing leftward and y increasing
upward). If you change the size of the viewport, you will also
need to change the parameters of the tick-generating model; like
other problems in typography and page layout, this is harder
than you might think.
