Thank you John!! In fact WXAgg does not have the same problems. I mean, there is no problem with WXAgg and fig.subplots_adjust(left=0.15, bottom=0.15) is even not needed! It looks much nicer : http://emmanuelfavrenicolin.free.fr/Public/Divers/Snapshots1/wx_snap1.png It means that WXAgg is to be the "recommend" way for embedding in wxpython? Just for reference, a "sample" code derived from dynamic_image_wxagg.py : #!/usr/bin/env python import sys, time, os, gc import matplotlib matplotlib.use('WXAgg') from matplotlib import rcParams rcParams['numerix'] = 'numarray' import matplotlib.cm as cm from matplotlib.backends.backend_wxagg import Toolbar, FigureCanvasWxAgg from matplotlib.figure import Figure import matplotlib.numerix as numpy from wxPython.wx import * TIMER_ID = wxNewId() class PlotFigure(wxFrame): def __init__(self): wxFrame.__init__(self, None, -1, "Test embedded wxFigure") self.fig = Figure((7,5), 75) #self.fig.subplots_adjust(left=0.15, bottom=0.15) self.canvas = FigureCanvasWxAgg(self, -1, self.fig) self.toolbar = Toolbar(self.canvas) self.toolbar.Realize() # On Windows, default frame size behaviour is incorrect # you don't need this under Linux tw, th = self.toolbar.GetSizeTuple() fw, fh = self.canvas.GetSizeTuple() self.toolbar.SetSize(wxSize(fw, th)) # Create a figure manager to manage things # Now put all into a sizer sizer = wxBoxSizer(wxVERTICAL) # This way of adding to sizer allows resizing sizer.Add(self.canvas, 1, wxLEFT|wxTOP|wxGROW) # Best to allow the toolbar to resize! sizer.Add(self.toolbar, 0, wxGROW) self.SetSizer(sizer) self.Fit() EVT_TIMER(self, TIMER_ID, self.onTimer) def init_plot_data(self): # jdh you can add a subplot directly from the fig rather than # the fig manager a = self.fig.add_subplot(111) a.set_title('Title') a.set_xlabel('Xaxis [u.a.]') a.set_ylabel('Yaxis [u.a.]') #a.xaxis.set_major_formatter(matplotlib.ticker.FormatStrFormatter('%5.2f')) #a.yaxis.set_major_formatter(matplotlib.ticker.FormatStrFormatter('%5.2f')) self.ind = numpy.arange(60) tmp = [] for i in range(60): tmp.append(numpy.sin((self.ind+i)*numpy.pi/15)) self.X = numpy.array(tmp) self.lines = a.plot(self.X[:,0],'o') self.count = 0 def GetToolBar(self): # You will need to override GetToolBar if you are using an # unmanaged toolbar in your frame return self.toolbar def onTimer(self, evt): self.count += 1 if self.count >= 60: self.count = 0 self.lines[0].set_data(self.ind, self.X[:,self.count]) self.canvas.draw() #self.canvas.gui_repaint() # jdh wxagg_draw calls this already def onEraseBackground(self, evt): # this is supposed to prevent redraw flicker on some X servers... pass if __name__ == '__main__': app = wxPySimpleApp() frame = PlotFigure() frame.init_plot_data() # Initialise the timer - wxPython requires this to be connected to # the receiving event handler t = wxTimer(frame, TIMER_ID) t.Start(100) frame.Show() app.MainLoop() ------------------------------------------------------------------------- Using Tomcat but need to do more?
