116 Statistics Graphics Toolkit
SetYscale (y1, y2)
SetYscale turns off auto-scaling for the Y axis, and forces the Statistics Graphics
Toolkit to use the range y1 to y2 for subsequent graphs. The Toolkit will continue to
use this range until you change it again, or use SetAutoScale to restore auto-scaling
for the Y axis, or your program stops.
This Toolkit rounds scales to good-looking numbers, so the final y scale may not be
exactly what you asked for.
AskYscale (y1, y2)
AskYscale returns the current range, running from y1 to y2, where y1 ≤ y2. If you’ve
previously called SetYscale, these values are the ones you supplied. Otherwise they’ll
be automatically computed from the data you gave.
GraphInit
GraphInit resets graph controls to their default values:
graph type xy grain 64
autoscale on spline order 3 *
axes on I-beam size 0
grid lines off mesh sizes 20 x 20 *
ticks LRBT least squares off
frame ticks ** axes ticks **
* Used by Scientific Graphics Toolkit only.
**
The number of pixels used for frame and axes ticks varies between computers and
may change in later versions of the Toolkit.
