Customize Signal Analyzer

Specify Line Color and Style

To specify the line style and color, click in the Line column of a signal. If the line column is not shown, add the column using the column selector button . Select a color from the palette and a line style. Click Custom to choose custom colors for your signals. You can specify custom colors as RGB triplets or as hexadecimal codes. For complex signals, the color that you set corresponds to the real part. The color of the imaginary part has the same hue and saturation with a different value of luminosity.

Add or Remove Columns in the Signal Table

Columns in the Signal table display the plot configuration and signal properties. To add or remove a column, click the column selector button . From the list, select the columns that you want to display and click OK. After you select a column, the new column is added to the table in the order that it appears in the column selection list.

Modify Signal Analyzer Displays

GoalAction
Hide the Workspace browser or the Signal table to enlarge the display area.

On the Analyzer tab, click one of the layout buttons.

Zoom and pan to inspect the data.

On the Display tab, select one of the zoom actions.

Alternatively, activate the panner by clicking Panner .

Fit spectrogram, scalogram, or persistence spectrum colormap to current power or density limits.

On the Display tab, click the Fit Colormap button .

Set the minimum and maximum values of the plot axes.

On the Time, Spectrum, Persistence Spectrum, Spectrogram, or Scalogram tab, enter the axes limit values. You can also change the minimum and maximum time values on the Display tab.

When setting axes for a display, you can specify time or frequency units before specifying limit values. Several engineering units are available:

QuantityUnits
Timeps, ns, μs, ms, seconds, minutes, hours, days, years
Frequencycycles/year, cycles/day, cycles/hour, cycles/minute, mHz, Hz, kHz, MHz, GHz, THz

Note

Selecting different time or frequency units for axes limit values does not change any plots.

Show or hide legends identifying plotted signals.

On the Display tab, click Legend .

Each display gets its own legend. The legends appear either at the top of the display or to the right of the display.

For each signal on a display, the legend shows the signal name and signal color. For complex signals, the first signal color represents the real part, and the second signal color represents the imaginary part.

Link or unlink a display.

Select a display. On the Display tab, select Link Time. Link Time is enabled only when there are two or more displays and at least one signal contains time information.

To unlink a display, select it and clear Link Time.

Frequency axes are never linked between displays.

Normalize the data for each signal from 0 to 1 along the y-axis of a time plot.

On the Time tab, select Normalize Y Axis.

Show markers at each sample point in a time plot of a signal.On the Time tab, select Show Markers.

Signal Analyzer Preferences

  • If you export or save signals that have time information but are not stored as timetables, the time information by default is not saved. If you want to preserve the time information by saving the signals as timetables, on the Analyzer tab, click Preferences and check Always use timetables when signals have time information.

  • If you generate scripts involving signals that have time information but are not stored as timetables, the time information by default is not saved. If you want to preserve the time information by generating scripts that treat signals as timetables, on the Analyzer tab, click Preferences and check Always use timetables when signals have time information.
