[Matplotlib-users] Use pyplot functions and embedded Qt widget
Hello. Can I use pyplot functions (such as pyplot.plot, pyplot.pcolormesh) to plot in embedded Qt plot? I have created the following class class CDeltaHPlot(FigureCanvasQTAgg): def __init__(self, parent = None): self.figure = Figure() self.axes = self.figure.add_subplot(111) FigureCanvasQTAgg.__init__(self, self.figure) self.setParent(parent) FigureCanvasQTAgg.setSizePolicy(self, QSizePolicy.Expanding, QSizePolicy.Expanding) FigureCanvasQTAgg.updateGeometry(self) self.plot() def plot(self): pyplot.sca(self.axes) But it throws the following exception: File /opt/develop/lib/python3.4/site-packages/matplotlib-1.4.0-py3.4-linux-x8 6_64.egg/matplotlib/pyplot.py, line 806, in sca raise ValueError(Axes instance argument was not found in a figure.) ValueError: Axes instance argument was not found in a figure. Kind regards, Petr. -- Slashdot TV. Videos for Nerds.

[Matplotlib-users] Using unregistered scales
MPL Users, Using [1] as a template, I built a ProbabilityScale[2] which I hope one day will be in the statsmodels library. It still needs some work, but it's mostly there. I have, what I hope is a basic question: Do I have to register the scale in order to use it, or is there an axes method to feed it the ProbScale class directly? I notice that there is an axes.xaxis._set_scale method -- but there appears to be no public API way of using an unregistered scale. If it is the case that there's no sanctioned way of applying an unregistered scale to an Axes object, when/where in a module is best to register it (e.g., on import, locally within a the function/method that needs it)?
