Display Options
Setting Description
Draw Average Draws a moving average line through the data points.
Plot Frame Specify the frame to draw if the Draw Average check box is cleared.
Chart Y Axis
Setting Description
Contrast Plots the contrast intensity information from the contrast data.
B-Mode Plots the grayscale intensity data from the B-Mode image.
Auto Scale View a system-calculated best-fit scale value.

Calculation
Setting Description
Power Sets the Y axis to B-Mode mean power (linear a.u.)
Amplitude Sets the Y axis to B-Mode mean amplitude (linear a.u.)
Radius Guide
The X axis Angle (deg) on the chart represents a flattened ellipse that surrounds
the short axis view. The radius guide helps you orient the plotted values by
illustrating how they correspond to sites within this short axis view.
For example, a point on the graph at the 225 mark on the x-axis corresponds to a
site along the 225 degree radius inside the guide.
