I haven't been able to find any licensing information for the color

Does anyone know what their license is, if any?

Could you be more specific about what you mean "don't work"? Do they
crash, do they have the wrong timezone, are the date strings formatted
improperly?

Yep, this looks like a threading problem. Could be a tough nut to
crack. Sorry, but I don't have any concrete suggestions for you.
Perhaps someone on the wx list would have some idea how to make wx
events play nicely with twisted threads.

The axes keeps a copy of the "dataLim" and won't automatically know if
you change the line's data. You need to call
 ax.update_datalim_numerix(x, y, ignore)
where x and y are the numerix arrays you pass to line.set_data.
If ignore is True, the previous data passed to the axes will be
ignored in computing the new datalim. If False, the datalim will
include the previous data and the current data you are passing it.
After this, a call to 
 ax.autoscale_view()
should work as you expect.

Hi all, and thanks for amazing matplotlib.
 I devellop my data processing / plotting software using glade,
pygtk, scipy and matplotlib 0.83.2.
I use the class library and I run into trouble with autoscaling.
I expected that autoscale_view() function of axes class would
do autoscaling. But if I update the data using set_data(),
set_xdatat() or set_ydata() (of lines object) and I call
autoscale_view() of the corresponding axes and then redraw
the canvas, the scale is not changed and some data points are
thus out of the picture.
Do I miss or misunderstand something ?

David

You have to interpolate the results to a common vector, and then perform
the difference. If you want to reproduce exactly the difference you can
see on-screen, then use a linear interpolation (cause the lines joining
successive points are straight, hence a linear interpolation - well,
assuming that your plot is in cartesian coordinates, else this becomes
more tricky), and map both set of results to the common vector
(list(x1)+list(x2)).sort() (remove duplicated values and reduce it to
the interval max(min(x1),min(x2)), min(max(x1),max(x2)) if you want to
be clean and safe...)

Hi,
you can look in the direction of polyfit, polyval function to do what do 
you want.

Try increasing the tick.major.pad in your rc settings (and also tick.minor.pad 
if needed).

Hi all,
I apologize for beeing slightly off-topic with this question, but I couldn't 
think about a better place to ask :-/
Consider two vectors x1 and y1. Using matplotlib, plot(x1,y1) will display the 
line joining all points whose coordinates are (x1(i),y1(i))
Now, consider another couple of vectors x2 and y2.
Using plot(x1,y1,x2,y2) we are shown the 2 lines corresponding to (x1,y1) and 
(x2,y2), and we can compare these two lines with the naked eye
My question is, how to do this quantitatively ? Is there a way of calculating 
the difference between the two sets of points, and then plot this difference, 
using matplotlib ? I mean, if the data was generated using a fixed grid, it 
would be enough to plot (y2-y1) but with an adaptative grid, x1 and x2 
differ. Do you know about a quick & dirty way to achieve this ?
Thanks in advance,
cheers,
Nicolas

Hi all,
I've a stubborn problem with labels near the origin of my pylab plots, where
the lowest tick label on the y-axis ends up touching the leftmost tick label
on the x-axis. Now, I can certainly tweak these manually with xticks and
yticks, but is there any automatic way to make this happen? More generally,
is there a way to specify "breathing room" distance between the first/last
tick mark and the beginning/end of the axis? Or to increase the distance
between label and tick mark?
Apologies if these are FAQs: I've looked everywhere I can think of at the
moment, and am now officially stuck :-)
Cheers,
Mike Sipior

Hi Benjamin,
Sorry but your code is still dependent on twisted:
Traceback (most recent call last):
 File "client.py", line 2, in ?
 from modules import mainwindow
 File "C:\Dev\BoaTest04\Benjamin\mat_test\modules\mainwindow.py", line=20
2, in ?
 from twisted.internet import wxreactor
ImportError: No module named twisted.internet
I don't have the time/nor interest (at least not at the moment) to get=20
twisted installed on my machine.
You should try to isolate your problem and part of that is probably to=20
get your matplotlib stuff NOT be dependent on a twisted feed, get the=20
data from a file or even just hard code it.

Hi
Sortof, but not really. I've just discovered something reeeally =
interesting.
I've produced a sample app that exhibits this behaviour. However, =
monitor.py
(in plugins/wx) still depends on twisted.spread.pb. If I comment out =
that
import, it all runs fine. (you can add data with the a button and the =
slider
in the left pane)
It's hard for me guess who is causing the troubles - whether it's =
matplotlib
not beeing able to handle the twisted threading or twisted breaking
matplotlib - I don't know

I have been able to trace down my problem a little - but it's not solved
yet.
I've added a self.axes.plot([0,1],[0,1]) when I'm adding a line to
self.axes. The first time I'm adding a line, I just see the 0,1 line. =
The
second time, I see the lines I want to see. However, the grid doesn't =
scale
(so the lines keep updating in an area that's not visible anymore.
Any ideas?

I was simply trying out the hint you gave me. I didn't expect it to =
solve my
problem, but I tried anyway.=20
I found it to be the easiest thing I can do just to send it my code. =
It's
not _that_ complex, though you need twisted installed (I don't know =
whether
it'll work with 1.3 - I'm working with 2.0) and you'll need wxpython 2.6
(I'm using features only present in 2.6)
My Attachement is a zip-file. I figured that the outgoing mailserver =
blocks
mail witz zip attachements :-/. First start server.py (in root-dir) - it
will generate the data, then start the client. In the sidebar (once the
client connected to the server) you can select/deselect sources. My idea =
is,
that data collection just goes on, and If I select a source, It displays =
me
all the data currently collected.
The code that has to do with the matplotlib stuff is located in
plugins/wx/monitor.py. Receive(self, data, source) is the retreival =
function
and EnableSource is supposed to enable drawing of a particular =
data-source.
Sorry for not doing a very simple testcase - but I think the code in
monitor.py is simple enough =20

It doesn't have to be anything complex, just the bare functionality of=20
whatever you're working on. I'll be happy to take a look at it=20
tomorrow.

I'm sorry if I gave you the impression that that was the problem...=20
it's a potential problem, but I didn't mean to suggest that it's why=20
your plot isn't being draw.
