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.
