**Decibel Y:** Rescales the *y*-axis to display the
values in decibels.

**External Trigger:** Determines whether Embed displays
simulation data in the strip chart based on the value of an external trigger.
When **External Trigger** is activated, Embed places a round input connector
on the stripChart block. When signal values entering the trigger are 1,
simulation data is displayed in the strip chart; when signal values entering the
trigger are 0, simulation data is not displayed.

**Fixed Bounds:** Specifies the region of the strip
chart you want to view by letting you select the plotting bounds. When
**Fixed** **Bounds** is activated, Embed uses the values for the **X**
**Upper** **Bound**, **X** **Lower** **Bound**, **Y**
**Upper** **Bound**, and **Y** **Lower** **Bound** parameters in
the **Axis** property sheet. Out-of-range signal values are clipped to the
existing strip chart bounds.

**Frequency Domain:** Obtains the frequency power
spectrum using the Fast Fourier Transform (FFT) algorithm.

Do not obtain frequency power spectrum data until after you have run a simulation. If you halt the simulation prematurely, the fidelity of the FFT is diminished.

If your frequency domain plot produces unexpected peaks,
check the simulation step size to verify that your sampling rate is adequate for
obtaining accurate results. Then, based on the simulation step size and range,
check **Plotted** **Points** to verify that you are indeed plotting each
time step.

**Geometric Markers:** Overlays signal traces with
geometric markers (squares, diamonds, circles, and triangles). These markers are
particularly useful for monochrome displays and printers.

**Grid Lines:** Extends grid lines from the vertical and
horizontal axis coordinates. The vertical and horizontal spacing of grid lines
is controlled by the spacing of the axis coordinates. Embed automatically
establishes reasonable axis coordinate spacing and hence controls the grid
frequency.

** Discrete:** Holds the
Y value constant from point to point. A discrete plot is helpful when data
points are irregularly spaced and you don’t know where the curve is
accurate.

** Line:** Connects data
points with solid line segments. On color displays, line segments are the color
of their corresponding input connector. On monochrome displays and printers,
patterns distinguish multiple signals. You may have to lower the point count in

** Point:** Displays signal
values as individual data points. The primary advantage of point plots is that
you can see the separation of data as time advances.

**Log Y:** Enables a logarithmic *y*-axis. Note
that you cannot plot negative values on a log axis. Any negative value is
clipped to the low end of the scale.

**Marker Count:** Determines the number of markers
overlaid on signal traces. A -1 means that all data points have markers
associated with them.

**Plotted Points:** Determines the smoothness and
accuracy of a plot. The more data points you plot, the smoother and more
accurate the plot. However, increasing the number of plotted data points also
increases the time it takes to print and display the plot. The maximum number of
data points that can be plotted is 128,000. For Windows NT and Windows 95,
the maximum number is 250 million.

**Read Coordinates:** Overlays the strip chart with a
set of crosshairs and displays crosshair position at the bottom of the chart.
When you click the left or right mouse button, Embed freezes the crosshairs.
Click the left mouse button again to erase the crosshairs.

**Retain Coordinates:** Displays two sets of crosshairs
on the strip chart. One crosshair is frozen at the last known *x,y*
position. The other is controlled by the position of the pointer.

**Save Data To File:** Saves the strip chart data to
file.
