By default, StampPlot plots data in respect to the time data arrived on the X-axis.

In many instances, a user may wish to dump data that has been locally to the controller and plot it in respect to the logged time.

There are 2 primary instructions to be used when plotting logged data:
!HISS [date/time]
!HISD [interval or date/time,value1,value2,...]

!HISS defines the starting time, and optionally date, the plot should begin. Use !RTIM ON to view the date/time on the X axis.

Sets the plot to start at the current date/time
!HISS

Sets the plot to start at today's date at 05:00
!HISS 05:00

Sets the plot to start on a specific date and time
!HISS 6/1/02 05:00

Once !HISS is issues, plotting may commence.  Plotting may be performed at a specific date and time, or as an interval since the last logged point.

Plot 20 at specific date/time
!HISD 6/1/02 05:30,20

Plots 50 and 100 (2 channels), 30 seconds after the last data
!HISD 30,50,100

Plots 25,75, 1 minute before the last data.
!HISD -60,25,75

Example plot configuration plotting from earliest to latest:
!HISS 6/1/02 05:00
!TMAX 6/2/02 05:00
!RTIM ON
'send data with positive intervals
!HISD 60,100

Example plot configuration plotting from lastest to earliest
!HISS 6/2/02 05:00
!TMIN 6/1/02 05:00
!RTIM ON
'send data with negative intervals
!HISD -60,100
