functions in style.i - g


    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.
