5.9 Displaying Real-time Harmonic Bar Graphs
Display a harmonic bar graph window by selecting
Harmonic Bar
from
the
View
menu. The real-time Harmonic Bar window will be displayed as
shown below.
Figure 5-32
The Harmonic Bar graph window shows the harmonic content of an asso-
ciated line cycle using a bar graph.
On the right side of this window, a list of available channels is displayed.
Clicking on an entry selects the corresponding channel for display. Clicking
on an entry that is not highlighted will highlight it, removing the highlight
from the previously highlighted channel, and displaying the harmonic bar
graph of the associated waveform. Clicking on an entry that is already
highlighted does nothing. The associated channel remains highlighted.
The real-time update can be paused by clicking on the
Hold
check
box. When checked, the automatic update will stop until the check is
removed.
The
Save
button allows you to store the data into a database.
