Re: [Matplotlib-users] Subaxes deletion issue

[Jae-Joon L. <lee...@gm...>]

The divider thing from axes_grid toolkit is primarily designed for a static
layout. So, it may become quite tricky when you want to adjust the layout
dynamically.

Here is a modified version your code that I think does what you want.

from matplotlib.figure import Figure
from mpl_toolkits.axes_grid.axes_divider import make_axes_locatable
from matplotlib.backends.backend_qt4agg import FigureCanvasQTAgg as
FigureCanvas
from PyQt4.QtCore import *
from PyQt4.QtGui import *
import sys

class Test(QWidget):
    def __init__(self):
        QWidget.__init__(self)
        self.resize(1000, 600)
        self.fig = Figure(figsize=(100,100), dpi=75)
        axes1 = self.fig.add_subplot(121)
        axes2 = self.fig.add_subplot(122)

        self.subaxes = []
        self.main_axes = [axes1, axes2]
        self.locators_orig = []
        for ax in [axes1, axes2]:
            make_axes_locatable(ax)
            self.locators_orig.append(ax.get_axes_locator())

            self.divider = make_axes_locatable(ax)
            self.subaxes.append(self.divider.append_axes("right", "40%",
"20%"))

        b = QPushButton("Remove subaxes")
        b.clicked.connect(self.OnBtnClicked)
        l = QHBoxLayout()
        l.addWidget(FigureCanvas(self.fig))
        l.addWidget(b)
        self.setLayout(l)

    def OnBtnClicked(self):
        for sa in self.subaxes:
            self.fig.delaxes(sa)
            del sa
        for ax, locator in zip(self.main_axes, self.locators_orig):
            ax.set_axes_locator(locator)
        self.fig.canvas.draw()

app = QApplication(sys.argv)
win = Test()
win.show()
sys.exit(app.exec_())


IHTH,

-JJ
