The State Chart subsystem provides the commands necessary for
programming the HP 1650B/51B's Chart display. The commands allow
you to build charts of label activity, using data normally found in the
Listing display. The chart's y-axis is used to show data values for the label
of your choice. The x-axis can be used in two different ways. In one, the
x-axis represents states (shown as rows in the State Listing display). In the
other, the x-axis represents the data values for another label. When states
are plotted along the x-axis, X and 0 markers are available. Since the
State Chart display is simply an alternative way of looking at the data in
the State Listing, the X and 0 markers can be manipulated through the
force the menus to switch, you can position the markers in the SLISt
subsystem and see the effects in the State Chart display.
The commands in the SCHart subsystem are:
