You currently have two options:

1) Use the Data Browser Widget

Create New Data Browser Plot,
add PV
Set desired axis and time range
Save as *.plt
Add Data Browser Widget to BOY
Set its File Name to the *.plt



++ Can also display archived data
++ PV can be Œmonitored¹, showing brief spikes
-- Fewer display options



2) Use XYGraph Widget

Configure Behavior,
Trigger PV: ³sim://noise²
(This PV updates once a second and will trigger plot updates)

Primary X Axis(0),
Time Format: ³HH:MM:ss²
(To get a "time' axis)

Configure Trace 0,
Trace Type: Step Horizontally,
Update Mode: Trigger,
Y PV: Name of PV to plot

++ Has many more display options
-- Cannot show archived data
-- PV scanned at update rate, can miss brief spikes
