View controls
The View controls (Figure 9-14) provide several
options for the X-Y Plot display.
Figure 9-14: View controls.
Pausing the display
The Pause button in the upper right corner of the
View section (Figure 9-14) allows you to freeze the
display at any time. To resume, click the button
again. The level meters will remain active while the
display is paused.
Line/Scatter
Choose either Line or Scatter from the menu in the
View section (Figure 9-14) to plot each point
(sample) as either a single pixel or as a continuous
line that connects each plot point to the next, as
shown below in Figure 9-15.

☛
Line mode is significantly more CPU intensive
than Scatter. You can reduce Line mode CPU
overhead on the X-Y Plot by reducing the Length
parameter (described below).
Color/Grayscale
In Color mode (Figure 9-14) the most recently
displayed audio data is shown in red, which fades
to yellow, green and then finally blue, before
disappearing. In Grayscale mode, data is first

shown in white and then fades to gray. To adjust the
scale of this color/brightness change, see "Decay"
on page 99.
Axes
The Axes control (Figure 9-14) sets the opacity of
the grid displayed in the graph, from 100% (fully
visible) down to 0% (fully hidden).
Horizontal and vertical controls
The Horizontal and Vertical controls (Figure 9-16)
configure the value range of the x-axis (left channel
amplitude), and y-axis (right channel amplitude),
respectively. Click and drag the values up or down
to set them, or double-click to return to the default
value.
There are two modes for the controls: Zoom/Offset
and Min/Max. To change the mode, use the menu
shown in Figure 9-16.
Figure 9-16: Setting the Horizontal or Vertical control modes.
In Zoom/Offset mode, Zoom scales the axis. Pos
moves the lines marking x = 0 left and right, or
y = 0 up and down.
In Min/Max mode, Min and Max let you scale the
grid by moving the -1.0 and +1.0 points along the
axis. Min/Max mode lets you control the graph
boundaries directly.
Persistence
The Persistence controls (Figure 9-17) affect the
appearance of data from when it is first displayed
until it disappears from the grid.
