WXAgg backend not rendering nicely on retina #7720
Description
When embedding a matplotlib plot in a WX.Panel, the figure_canvas is not rendered nicely on a retina display. Increasing the dpi of the figure does not help (it only alters the figure size).
Matplotlib version: 2.0.0rc2 (installed with pip) (same behaviour as with 1.5.3)
Python version: 2.7.13 (installed with homebrew)
Platform: OSX (macOS Sierra)
Plotting using standard MacOSX backend (no embedding):
import matplotlib
matplotlib.use("MacOSX") #put here explicitly for reference
from numpy import arange, sin, pi
import matplotlib.pyplot as plt
figure = plt.figure()
axes = figure.add_subplot(111)
t = arange(0.0, 3.0, 0.01)
s = sin(2 * pi * t)
axes.plot(t, s)
plt.show()
Plotting using the WXAgg backend (embed inside WX.Panel):
from numpy import arange, sin, pi
import matplotlib
matplotlib.use('WXAgg')
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas
from matplotlib.backends.backend_wx import NavigationToolbar2Wx
from matplotlib.figure import Figure
import wx
class CanvasPanel(wx.Panel):
def __init__(self, parent):
wx.Panel.__init__(self, parent)
self.figure = Figure()
self.axes = self.figure.add_subplot(111)
self.canvas = FigureCanvas(self, -1, self.figure)
self.sizer = wx.BoxSizer(wx.VERTICAL)
self.sizer.Add(self.canvas, 1, wx.LEFT | wx.TOP | wx.GROW)
self.SetSizer(self.sizer)
self.Fit()
def draw(self):
t = arange(0.0, 3.0, 0.01)
s = sin(2 * pi * t)
self.axes.plot(t, s)
if __name__ == "__main__":
app = wx.App()
fr = wx.Frame(None, title='test')
panel = CanvasPanel(fr)
panel.draw()
fr.Show()
app.MainLoop()
Any workarounds or tips?
