This control is experimental. It is missing some important features, and the interface may be changed in a future version.
The Spectrogram Layer Control ()
plots a spectrum at successive (usually, but not necessarily,
regularly-spaced) points in a time series.
It is only available for the
Time Plot Window;
you can add one of these controls to the stack by using the
Add Spectrogram Control (
) button
in the control panel toolbar,
or the corresponding item in the Layers menu.
Time Plot window with a Spectrogram layer
This control has only one layer-specific tab, Data, described below. The Zone tab is described in Appendix A.4.14.1.
To control the colour map used to represent the spectral values,
use the Aux fixed control.
