Detailed Description

A graphical sink to display multiple signals on a waterfall (spectrogram) plot.

This is a QT-based graphical sink the takes set of a floating point streams and plots a waterfall (spectrogram) plot.

Note that unlike the other qtgui sinks, this one does not support multiple input streams. We have yet to figure out a good way to display multiple, independent signals on this kind of a plot. If there are any suggestions or examples of this, we would love to see them. Otherwise, to display multiple signals here, it's probably best to sum the signals together and connect that here.

The sink supports plotting streaming float data or messages. The message port is named "in". The two modes cannot be used simultaneously, and nconnections should be set to 0 when using the message mode. GRC handles this issue by providing the "Float Message" type that removes the streaming port(s).

This sink can plot messages that contain either uniform vectors of float 32 values (pmt::is_f32vector) or PDUs where the data is a uniform vector of float 32 values.

Message Ports:

freq (input): Receives a PMT pair: (intern("freq"), double(frequency)). This is used to retune the center frequency of the display's x-axis.
bw (input): Receives a PMT pair: (intern("bw"), double(bandwidth)). This is used to programmatically change the bandwidth of of the display's x-axis.
freq (output): Produces a PMT pair with (intern("freq"), double(frequency)). When a user double-clicks on the display, the block produces and emits a message containing the frequency of where on the x-axis the user clicked. This value can be used by other blocks to update their frequency setting.

To perform click-to-tune behavior, this output 'freq' port can be redirected to this block's input 'freq' port to catch the message and update the center frequency of the display.

Build a floating point waterfall sink.

Parameters

size	size of the FFT to compute and display. If using the PDU message port to plot samples, the length of each PDU must be a multiple of the FFT size.
wintype	type of window to apply (see gr::fft::window::win_type)
fc	center frequency of signal (use for x-axis labels)
bw	bandwidth of signal (used to set x-axis labels)
name	title for the plot
nconnections	number of signals to be connected to the sink. The PDU message port is always available for a connection, and this value must be set to 0 if only the PDU message port is being used.
parent	a QWidget parent object, if any
