[Matplotlib-users] getting the min and max values of an axis for plotting
hello, I have a function, which I am plotting. I want to add a line positioned at, say, the mean of the function, so I want to do plot([x,x],[y0,y1]). In order to get y0, and y1, my brute force trial and error browsing of the API lead me to : y0=gca().yaxis.get_majorticklabels()[0].get_position()[1] y1=gca().yaxis.get_majorticklabels()[-1].get_position()[1] and as I am never contented, I now ask : is it really the manner of choice to get this information. I sense that I did not take the straightest path to get it :) thanks in advance, Johann - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

[Matplotlib-users] [newb] batch processing
To produce a batch of pdfs, I'm using: close () figure (1, figsize=(11,8)) ... savefig (open (whatever, 'w')) Works, but causes my display to flash, I think each time either close() or figure() is called (not sure which). Any better way? - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event. There's still time to save $100.

To avoid opening a window at all, use a non-interactive backend by
putting something like the following at the start of your script,
_before_ importing anything else:
import matplotlib
matplotlib.use('pdf')

[Matplotlib-users] tkinter segv under opensuse 10.3
Hi,
I had a look through the archives but couldn't find an answer to this.
Using the tkagg backend (agg is fine) I get a segmentation fault
doing a simple plot.
gdb returns the following:
362 Point* ll_api() {return _ll;}
Current language: auto; currently c++
(gdb) bt
#0 0xb6fc1bac in PyAggImagePhoto (clientdata=0x0, interp=0x87a9430,
argc=5,
argv=0xbf97fc9c) at src/_transforms.h:362
#1 0xb712ea5c in TclInvokeStringCommand () from /usr/lib/libtcl8.4.so
#2 0xb712ff05 in TclEvalObjvInternal () from /usr/lib/libtcl8.4.so
#3 0xb7131015 in Tcl_EvalObjv () from /usr/lib/libtcl8.4.so
#4 0xb73d34a6 in ?? () from /usr/lib/python2.5/lib-dynload/_tkinter.so
snip
This is matplotlib-0.91.2, python 2.5 on linux (opensuse 10.3)
Cheers,
Malte.

[Matplotlib-users] closing windows matplotlib and tkinter
I have a simple window to open a file that the data is then used to make a
graph:
The code for that part is:
=code
window = Tkinter.Tk()
#window.withdraw() -- not sure what this does
window.title('hello world')
w = Tkinter.Label(window,text=hello, again)
w.pack
menubar = Tkinter.Menu(window)
mfile = Tkinter.Menu(menubar, tearoff = 0)
mfile.add_command(label=Open, command=callback)
mfile.add_command(label=Save, command=callback)
menubar.add_cascade(label=File, menu=mfile)
window.config(menu=menubar)
errmsg = 'Error!'
of_But = Tkinter.Button(window, text= Open File, command=callback)
of_But.pack()
#Button(text='Quit', command=(lambda: showerror('Sure you want to
quit?', errmsg))).pack(fill=X)
q = Tkinter.Button(window, text=Quit, fg=red, command=window.quit)
q.pack()
window.mainloop()
I then create a map :
=code=
m1 =
Basemap(llcrnrlon=-119,llcrnrlat=22,urcrnrlon=-64,urcrnrlat=49,\
projection='lcc',lat_1=33,lat_2=45,lon_0=-95,resolution='l')
shp_info =
m1.readshapefile(r'C:\Python25\Lib\basemap-0.9.9.1\examples\citiesx020','states',drawbounds=True)
ax=p.gca()
seqnum={}
criteriatodisplay=[]
names={}
for seq, shapedict in enumerate(m1.states_info):
if int(shapedict['POP_2000'])15:
seqnum[seq]=shapedict['NAME']
criteriatodisplay.append(seq)
m1.drawcoastlines()
m1.fillcontinents()
m1.drawcountries()
m1.drawstates()
m1.drawparallels(p.arange(25,65,4),labels=[1,0,0,0])
m1.drawmeridians(p.arange(-120,-40,4),labels=[0,0,0,1])
p.show()
==
But when I click on quit, I get this error:
Fatal Python error: PyEval_RestoreThread: NULL tstate
This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application's support team for more information.
It's not that big of a deal since I'm quitting anyways, but does anyone know
how to fix this?
Kurt

Re: [Matplotlib-users] Non-linear Regression to a Histogram
I have an example of fitting distributions to bus arrival times using 'R' that may be helpful. I wanted to calculate the latest time I could arrive at the bus stop and have a better than 95% chance of catching the bus. I tend to use R and Scipy whereever each is strongest. http://www.oplnk.net/~ajackson/software/ http://www.oplnk.net/~ajackson/software/BusStats.R On Sun, 11 May 2008 18:49:58 -0500 glenn andrews [EMAIL PROTECTED] wrote: I have been working on a similar problem related to finance.

Keep in mind that R also has good plotting capabilities and you might just go with that solution. ### Eric Firing wrote: You might get a good answer here (although I don't have it), but be aware that your question relates to math, not plotting, so it is not really a matplotlib question. You need nonlinear least-squares. Look in scipy, and try the amazing Google.
