7.8.6. Setting the Phase Bar Graph Type
Bar graphs
There are two types of phase bar graphs available: one that has a
focus of presenting the amount and L/R distribution of stereo content
(STEREO), and one that presents in-phase/out-of-phase proportions
(DIN).

7.8.7. Setting the Bar Graph Error Region
Bar graphs
The bar graph "error" region is the area from clipping (0 dB FS) down
to the level selected by this control. It is intended to tell the user when
the audio signal is getting close to clipping.
Warning:
Some bar graph types (and ballistics) have this region defined. When
you select one of these types, this value will automatically be set.
After you choose the type, you can adjust this value to your desired
level.

7.8.8. Setting the Bar Graph Warning Region
Bar graphs
The bar graph "warning" region is the area between the "OK" region
and the "error" region. It is intended to indicate when the audio level is
approaching the "error" region. This control sets the bottom of the
"warning" region. Normally, it is set to the audio program level. The
upper boundary of this region is always set with the "error" region
control.
This value cannot be higher than the "error" region value. If the "error"
region is lowered below the value of this parameter, the "warning"
region will also be lowered.
Warning:
Some bar graph types (and ballistics) have this region defined. When
you select one of these types, this value will automatically be set. After
you choose the type, you can adjust this value to your desired level.

7.8.9. Setting the Level Bar Graph Scale Position
Bar graphs
This control allows you to enable and position the level bar graph
scale tick marks and the scale labels with respect to the bar itself.
When off, there will not be any ticks or numerical labels while left or
right will position them to the left or the right of the graphs
respectively.
If a combination VU/PPM mode is selected, then "left" will select VU
scale on the left, PPM scale on the right and "right" will select VU
scale on the right and PPM scale on the left.
