132 Statistics Graphics Toolkit
AskAspect (r)
AskAspect returns the current ratio r used to compensate for your computer
monitor’s aspect ratio. This number varies, depending on the kind of computer you’re
using and what mode it’s in.
———————————————————————————————————————
x NOTE: Switch to the right graphics mode before you call AskAspect –
it returns the aspect ratio for your current mode.
———————————————————————————————————————
If you’ve used SetAspect to establish the ratio, AskAspect will return whatever
you’ve said.
SetMargins (left, right, bottom, top)
SetMargins controls the pixel margins around the frame. These margins are the
unused space between the edge of the window and the edge of the frame. You can use
this to change the positioning of graphs within a window.
The parameters control the left, right, bottom and top margins respectively. These
new margins will stay in effect until your program stops, or you call SetMargins
again.
By default, all margins are 0. Therefore the entire current window is used for the
frame. But if you call SetMargins(1,2,3,4), for example, then the frame will be drawn
a little bit smaller. There will be 1 unused pixel on the left side of the window, 2 on
the right side, 3 on the bottom, and 4 on the top.
AskMargins (left, right, bottom, top)
AskMargins returns the current frame pixel margins in left, right, bottom and top.
SetTickSizes (h, v)
SetTickSizes sets the current pixel sizes of the horizontal and vertical ticks. These
sizes are used both for the ticks drawn along the frame and for the ticks drawn on
axes. Tick sizes less than 1 pixel mean that no ticks are drawn.
AskTickSizes (h, v)
AskTickSizes returns the current sizes, in pixels, of the horizontal and vertical ticks.
