Hello, I graph of weather data from a CGI script using the Agg backend only. The graph is a common time vs. temperature 2D line plot. Since the graph plots every n minutes, the lines on the graph tend to look pointed and not very aesthetically pleasing (as many people have informed me.) I did some research and found I needed to do curve fitting. I'm trying to use 8th order polynomial fitting. I have found a sample on the Web that shows how to use matplotlib to do a best-fit line from polyfit, but I want a curve that follows the curve of weather temperature data. I plot the data using a list of X-coordinates and a list of Y-coordinates. I assume I can call polyfit with (x,y,8) for 8th order polynomial fitting. However, I am not sure what to do with the results. I have tried to translate the 1st order polyfit example for my needs but I don't think I am using the polyfit data correctly. Also, it has been suggested that a spline or Butterworth filter on the data may yield more predictable results. I have found some of this functionality in SciPy and a nifty module in a language called Octave. Would matplotlib benefit from this? Any assistance is much appreciated. I'm just starting out on this type of stuff but it is fascinating to work with! Thank you, Brian

Check the > following code Hmm, could you explain why you want to avoid the wx mainloop, and what you mean by this. Do want wx to process events, right? You say you're trying to embed matplotlib on WX, but the code you posted doesn't do this. It uses pylab, which creates a wx App and runs its mainloop when you do show(). My guess is that you're probably start getting the behavior you expect once that auto-created wxapp is killed. A simple answer would be to not use pylab, and just use a matplotlib FigureCanvas with wx. You'd have a mainloop then (I don't see how you avoid that!!). You could start another thread for non-GUI processing if you wanted, or *use* the mainloop's events (timers or data-changing events) to update the plot. Hope that helps, --Matt

This was a parser bug in mathtext which is fixed in CVS. Be sure and
let me know when you encounter these kinds of problems since they are
usually easy to fix
While I was at it, I also implemented unicode support for the *Agg and
PS backends :-) If you have access to CVS, you may want to give it a
test drive. See examples/unicode_demo.py. CVS mirrors may lag.

Jan, On many lists, asking 'please help me' three times in under twelve hours is liable to get you no help at all, and quite possibly prevent people from helping you in the future. > could anyone show me how to incorporate this example on my GUI? > > what i want to do is to implement this in a wxPanel that is > part of my wxFrame, but i am getting errors that says wxPanel > instance has no attribute GetToolBar... The embedding_in_wx*.py examples didn't help?? The code you posted doesn't have a wxPanel or a wxFrame, so it's difficult to say what the problem might be or what you actually want to do. In general, you can put a FigureCanvasXXX on a wxPanel or wxFrame. A simple example putting a figure on a wxPanel is below. Hope that helps, --Matt import wx from matplotlib.numerix import arange, sin, pi from matplotlib.figure import Figure from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg class PlotPanel(wx.Panel): def __init__(self,parent=None): wx.Panel.__init__(self,parent,-1) self.fig = Figure((5,4), 75) self.canvas = FigureCanvasWxAgg(self,-1,self.fig) self.axes = self.fig.add_axes([0.12,0.12,0.76,0.76]) sizer = wx.BoxSizer(wx.VERTICAL) sizer.Add(self.canvas,1, wx.LEFT|wx.TOP) self.SetSizer(sizer) ; self.Fit() def plot(self,x,y): self.axes.cla() self.axes.plot(x,y) class PlotFrame(wx.Frame): def __init__(self,parent=None): wx.Frame.__init__(self,parent,-1,'Frame') self.plotpanel = PlotPanel(self) sizer = wx.BoxSizer(wx.VERTICAL) sizer.Add(wx.StaticText(self, -1 , ' WX Matplotlib example ') ,0, wx.LEFT|wx.TOP) sizer.Add(self.plotpanel,1, wx.LEFT|wx.TOP) self.SetSizer(sizer) ; self.Fit() def plot(self,x,y): self.plotpanel.plot(x,y) if __name__ == '__main__': app = wx.PySimpleApp() frame = PlotFrame() x = arange(0,10.0,0.025) y = sin(x*pi/2) frame.plot(x,y) frame.Show() app.MainLoop()

All of the date ticker locators accept ranges to indicate where you
want the ticks. See, eg,
http://matplotlib.sourceforge.net/matplotlib.dates.html#MinuteLocator
To tick every 5 minutes, just give the range of minutes you want
ticked
loc = MinuteLocator(range(5,60,5)) # don't tick on 0 and 60
loc = MinuteLocator(range(0,61,5)) # tick on 0 and 60 as well
The default is to tick on every minute...

Hello all, I am trying to install matplotlib for Python 2.3 under Linux (Mandrake 10.1 AMD64) and the installation fails while trying to perform the build command. I checked for the prerequisite and all the recommended packages seem to be correctly installed. I am unable to understand the compilation error as it does not look like a trivial error (include file missing, library not reachable, ....) and as my C++ and Python skills are yet very weak. The error is reproduced hereafter: [root@TigerBox matplotlib-0.73.1]# python setup.py build running build running build_py running build_ext building 'matplotlib.backends._gtkagg' extension creating
