Creating Rectangular Plots
A rectangular plot is a 2D, x-y graph of simulation results.
You must define a solution setup before attempting to create a rectangular plot.
To create a rectangular plot:
- Select Twin Builder > Results > Create Standard Report > Rectangular Plot. The Report dialog box appears.
- In the Context section make selections
from the following field or fields, depending on the design and solution
type.
- Solution – This lists the available solutions, whether sweeps or adaptive passes.
- Domain – Whether this field appears, and
the domains listed depend on the solution type and the <type> selected. The domain can be Sweep, Spectral, or Time.
When Spectral is selected, additional fields display in which you can make settings for plotting spectral domain data. The magnitude function mag() is also applied to quantities selected for plotting in the Y field.
- Optimetrics setup – All defined Optimetrics analysis setups.
- Select Quantities – Opens the Select Quantities dialog box in which you can select additional quantities for plotting.
- Under the Trace
tab, Y component section, specify
the information to plot along the Y-axis:
- Category – Select the type of information to plot.
- Quantity – Select the value to plot.
- Function – Select the mathematical function of the quantity to plot.
- The Y field displays the currently
specified quantity and function. You can edit this field directly.
Note:
- The text color shows whether the expression is valid (blue for valid expressions, red for invalid).
- When Spectral is selected, the magnitude function mag() is applied to quantities selected for plotting in the Y field.
- Range Function – Click to open the Set Range Function dialog box. This applies currently specified quantity and function.
- On the Trace
tab, X (primary sweep) line,
specify the quantity to plot along the X-axis in one of the following
ways:
- Select the sweep variable to use from the drop-down list.
- If sweeps are available,
to find and select sweeps. The quantity is plotted against the primary
sweep variable listed.
- On the Families tab, confirm or modify the sweep variables to be plotted.
- Click New Report.
This creates a new report in the Project tree, displays the report with the defined trace, and enables the Add Trace button on the Report dialog box. The default name is based on the report category you selected (for example, S Parameter Plot n or rE Plot n). You can edit the plot names in the Project tree and the plot header text in the report synchronizes.
The function of the selected quantity is plotted against the swept variable values or quantities you specified on an x-y graph. The plot is listed under Results in the Project tree and the traces are listed under the plot. The default name is based on the report category you selected, (for example, S Parameter Plot n or rE Plott n). You can edit the plot names in the Project tree, and the plot header text in the report synchronizes. When you move the mouse pointer close to a trace, the quantity name of that trace is displayed in a box that appears next to the cursor. When you hover the mouse over a trace in the Curve Info box, the corresponding trace changes color. When you select the traces or plots, their properties display in the Properties window. You can edit these properties to modify the plot.
- Optionally, add another trace to the plot by following the procedure above, using Add Trace rather than New Report.
