Re: [Matplotlib-users] Multiple plots, interactivity, wx etc
Hello,
How can I do this using mpl and wx backend? Do you recommend using
threading or forking plots as separate processes ?
None of the above is necessary.
Add this to imports:
import matplotlib
matplotlib.use('WXAgg')
import matplotlib.cm as cm
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg
from matplotlib.figure import Figure
from pylab import *
Just instanciate some wx.panel with inside
self.sizer = wx.BoxSizer(wx.VERTICAL)
fig = Figure()
self.figure = FigureCanvasWxAgg(self.widget, -1, fig)
self.sizer.Add(self.figure, 1, wx.EXPAND)
x1 = array(var1['data'])
y1 = array(var1['data'])
axes = fig.add_subplot(111)#211)
axes.yaxis.tick_left()
axes.plot(x1,y1,alpha=1)
And should be OK.
Personnaly I use wx.aui to manage multpile wx.panel inside an App, but it
depends what you want to do with your app.
