31 // Simple interface for defining viewport and window.
32 //
33 // The "just" parameter control how the axes will be scaled:
34 //
35 // just=-1 : The scales will not be set, the user must set up the scale
36 // before calling plenv() using plsvpa(), plvasp() or other;
37 // just= 0 : The scales will be set up to optimize plot area;
38 // just= 1 : The scales will be the same;
39 // just= 2 : The axes will be equal, the plot box will be square.
40 //
41 // The "axis" parameter is interpreted as follows:
42 //
43 // axis=-2 : draw no box, no tick marks, no numeric tick labels, no axes.
44 // axis=-1 : draw box only.
45 // axis= 0 : Draw box, ticks, and numeric tick labels.
46 // axis= 1 : Also draw coordinate axes at X=0, and Y=0.
47 // axis= 2 : Also draw a grid at major tick positions in both coordinates.
48 // axis= 3 : Same as 2, but the grid will be also at the minor ticks.
49 // axis=10 : Same as 0 except Logarithmic X tick marks. (The X data have
50 // to be converted to logarithms separately.)
51 // axis=11 : Same as 1 except Logarithmic X tick marks. (The X data have
52 // to be converted to logarithms separately.)
53 // axis=12 : Same as 2 except Logarithmic X tick marks. (The X data have
54 // to be converted to logarithms separately.)
55 // axis=13 : Same as 12, but the grid will be also at the minor ticks.

59 // to be converted to logarithms separately.)
60 // axis=22 : Same as 2 except Logarithmic Y tick marks. (The Y data have
61 // to be converted to logarithms separately.)
62 // axis=23 : Same as 22, but the grid will be also at the minor ticks.
63 // axis=30 : Same as 0 except Logarithmic X,Y tick marks. (The X,Y data have
64 // to be converted to logarithms separately.)
