pothosplotters's Introduction

Plotters for visualization in Pothos GUI

The plotters toolkit provides plotter widgets which are combined processing blocks with Qt widgets which are capable of displaying signal visualization within the Pothos GUI. Such blocks include: time-domain waveform viewer, periodogram, spectrogram, constellation plotter, and others

option to hide labels on wave monitor

QWT paths on cmake

In MacPorts we can have multiple QWT versions so I need to pass as parameters where to find the right one, in this case QWT 6. Unfortunately the following doesn't work

    -DQWT_INCLUDE_DIRS=${qt_dir}/lib/qwt.framework/Versions/6/Headers \                                                                                                                           
    -DQWT_LIBRARIES=${qt_dir}/lib/qwt.framework/qwt

Probably, CMakeLists.txt needs to set this value. thanks

WaveMonitor can leak exceptions into Qt and crashes PothosFlow

When plotting data with no data type convert throws in WaveMonitorDisplay::handleSamples().
Other blocks log this as a warning, I assume they do this conversion in there work() method.

fft plotters need a full-scale parameter

From @guruofquality on March 29, 2016 20:58

Currently fullscale is assumed to be 1.0. To better handle fixed point data (and really anything) there should be a parameter that specifies what is full-scale (defaulting to 1.0).

Copied from original issue: pothosware/PothosWidgets#36

display positive spectrum for real signals

Add an axis option for both FFT-based plotters to display full-spectrum, positive, or automatic based on data type (default can be automatic).

integration for various Qwt widgets

Qwt widgets are in the plotters toolkit for their Qwt dependency. So far, only slider has been wrapped as an example: https://github.com/pothosware/pothos-plotters/tree/master/QwtWidgets

qwt thermo -- displays a probe's value
qwt dial -- controls a value like a slider

Copy over IP from pothos-widgets

Top level issue: pothosware/PothosCore#28
Also port pothos-widgets issues about plotters: https://github.com/pothosware/pothos-widgets/issues
Remove plotters from pothos-widgets codebase

wave viewer/periodogram - wait for all ports before replot

The multi-channel plotters should ensure that the entire display is only refreshed after all N channels have arrived. Otherwise we are not necessarily looking at curves from the same time.

periodogram does not save zoom on close + reopen

Support for trigger labels (periodogram and spectrogram)

The trigger label allows the internal trigger block to align to a label. If the stream is bursty rather than continuous, this will ensure that the bursts align with fft boundaries.

add slot to clear plotter traces

eye diagram plotter for digital waveforms

https://en.wikipedia.org/wiki/Eye_pattern

hide+show control/auto-hide for plotter legend

The legend can stick out like an eyesore, especially when the plotters are small. Its used for setting channel visibility. We could have a show/hide enum in the options panel. Or just auto-hide it when not moused over the edge.

reusable property edit widget for window function selection

In the same style of pothos-gui edit wigets:
https://github.com/pothosware/pothos-gui/tree/master/EditWidgets

Any arbitrary widget can be registered into the property tree at "/gui/EntryWidgets/*"

This window function edit widget can be used in Periodigram, Spectrogram, and pothos-blocks taps designer block.

dB values seam to be incorrect on both Periodogram & Spectrogram

When display a single test tone of amplitude 1.0 in the Periodogram or Spectrogram display the amplitude seams down from were it should be. 3dB down for complex and 9dB down for real signals.
It does not seam to be significantly affected by the windowing mode.
But adjusting the "Full Scale" parm fixes the the issue. eg 1.0 *sqrt(1/2) for complex bring the displayed amplitude to were i would expect.

I see this bug under the Pothos v0.7.0-g42d23cb1

OS X 10.11.2 / homebrew: Adding any plotter block causes PothosGui to segfault or fail assertion

Any time I try to add any of the plotters (constellation, logic, periodogram, spectrogram, wave monitor) to my flow graph, PothosGui either segfaults or fails an assertion.

Here's the output from me running PothosGui and double-clicking on Spectrogram with an empty flowgraph:

juroujin:~ meatmanek$ PothosGui
2015-12-22 21:41:17 PothosGui.MainWindow: Welcome to Pothos v0.3.0-unknown

Segmentation fault: 11
juroujin:~ meatmanek$

Traceback from the crash report dialog: https://gist.github.com/EvanKrall/9316862740a977008937

If I add another block to the graph first, however, I get an assertion failure. This is the output of me adding a noise source and then a spectrogram plotter:
