7.2.4 Graph Scale
The GRAPH SCALE function allows the selection of the graph settings for
each zone (1, 2, 3, or 4). Graph settings for each zone are used in common
among all display layouts. This may be password-protected (see Section 7.5.4,
Password). For each zone you may set the center of the vertical axes for the
temperature graphs (T CENT), the temperature scale for the axes (T SCAL),
the center of the vertical axes for the humidity graphs (H CENT), the humidity
scale for the axes (H SCAL), the time axis scale (TIME), and the number of
grid divisions for the graph (DIVS). Following is the range for each setting:
T CENT from 100.000 to -40.000
T SCAL from 100.000 to 0.100
H CENT from 100.000 to 0.000
H SCAL from 100.000 to 1.000
