Re: [Matplotlib-users] "ValueError: oridinal must be >= 1" with 0.98.1 - non with 0.98.0
I used to have such errors when I was trying to display empty vectors. But since you're saying that the script work on previous version of Matplotlib... Sorry if it hasn't helped.

Re: [Matplotlib-users] Ubuntu Hardy and matplotlib
Hi The thing is that if you installed the package matplotlib through your package manager, you are not supposed and you don't need to install it manually from the sources with the two commands I gave you. The main interest of using the source of 0.91.3 is to use a debugged version of the 0.91 release. In fact, the package 0.91.2 that you can get from your package manager still have some bugs. But maybe, you are using the 0.91.3 version since you typed "pyhton setup.py build" and "pyhton setup.py install" in the source directory (despite of the fact that you previously installed a matplotlib package). I'm not good enough in Linux to tell what is the behaviour of the system in this case. Anyway, good for you if it's actually working. :) Regards Johan 2008/6/17 Marjolaine Rouault <[EMAIL PROTECTED]>: > Dear Johan, > > I have downloaded the matplotlib 0.91.2 version (the one installed by > default by my package manager) and ran the python setup.py build as you > suggested before running the python setup.py install command.

[Matplotlib-users] Align x axises with data vectors of different size
Hi I display two data vectors : the first is in the subplot 2,1,1 and the second in the subplot 2,1,2. Each of the data vectors have an x vector of dates to display values on x axis. The 2 data vectors are correlated in time and I want to show the correlation. But the two data vectors are not aligned as I wanted them to be since the data vector of subplot 2,1,2 have less element than the other one. I can't use the same x vector for both curves since it would force me to add empty values in the second data vector. And I don't want to do that since it would add useless points in my curve. So I need to find a way to allow me to align both data vectors on the different subplots without adding point to the data vector with a smaller number of elements.

Hi I'd like to know when the latest packages in *.deb or *.rpm (from the 0.98.0 version) will be available in the repositories ?

[Matplotlib-users] Remove xlabel
Hi
I'm plotting data associated with dates.
I have two problems.
The first one is that the xlabel "date" is displayed despite that haven't
set Matplotlib to do so.
My code is the following one :
fig = plt.figure(1)
title_to_display=str("Entropy, Kullback-LeiblerL, symmetric KL
and resistor KL from %s to
%s"%(IP_list_RTT[i][0].split("_")[1],IP_list_RTT[i][0].split("_")[2]))
ax_1 = fig.add_subplot(2,2,1)
ax_1.plot(dates_RTT,data_RTT,'r-')
ax_2 = twinx()
ax_2.plot(dates_distances,entropy_list)
ax_2.plot(dates_distances,kullback_leibler_list)
ax_2.plot(dates_distances,symmetric_kullback_leibler_list)
ax_2.plot(dates_distances,resistor_average_kullback_leibler_list)
ax_2.yaxis.tick_right()
title(title_to_display,fontsize=size_font_title)
ax_1.grid(True)
ax_1.xaxis.set_major_formatter(formatter_1)
ax_2.xaxis.set_major_formatter(formatter_2)
labels_x1 = ax_1.get_xticklabels()
labels_x2 = ax_2.get_xticklabels()
setp(labels_x1, rotation=rotation_x_label,
fontsize=size_font_x_label)
setp(labels_x2, rotation=rotation_x_label,
fontsize=size_font_x_label)
All the variables relatives to the display
(rotation_x_label,size_font_x_label,size_font_title) are defined before.
If I add xlabel("tutut"), I just get "tutut" print over the two previous
"date" (one for ax_1 and one for ax_2).
It also looks like there is two x tick labels formatted displayed.
I tried to define two formatters with one empty and one "normal" and assign
them to the two different axes that I'm using with something like this :
formatter_1 = DateFormatter('')
formatter_2 = DateFormatter('%H-%M-%S')
and then :
ax_1.xaxis.set_major_formatter(formatter_1)
ax_2.xaxis.set_major_formatter(formatter_2)
But it doesn't work.
If the empty formatter is the first one, it looks that both x tick labels
are displayed at the same time (just as before). And if the empty formatter
is the second, none of the x tick labels are displayed.
Thanks in advance for the help.
Regards.
Johan Mazel

Re: [Matplotlib-users] Plot data with specified time (hour, minute, second)
Hello
I think that my problem is linked to the data struture that I'm using for
the dates since my error message is : "ValueError: setting an array element
with a sequence."
I use list data structure, the one that you can declare through :
datetime_list = [].
And maybe I souldn't use this type of data structure and another one.

Re: [Matplotlib-users] Plot data with specified time (hour, minute, second)
Ok.
I tried to do the job through the old way and it's working.
But I have the latest version (0.91.2). Is it possible that my version
wasn't successfully installed and that an older one is doing the job ?
Anyway, thanks a lot for the (fast) help.

[Matplotlib-users] Fwd: Plot data with specified time (hour, minute, second)

When you wrote "import matplotlib.ticker", you meant "from matplotlib.dates
import ticker" ?
I think I have a bug or something because I get an error like "ValueError:
setting an array element with a sequence." with a lot of debug stuff from
python and MatPlotLib
The line concerned is the one where I do plot(datetime_list,data_list).
It's very strange because just before I use "my_datetime.strftime("%d %H %M
%S")" with my_datetime as an element of my list and it works perfectly.
Anyway, thanks a lot for the help.

Re: [Matplotlib-users] Plot data with specified time (hour, minute, second)
Ok.
I manage to get either time or date but not both inside the same object .
And I don't know how to use plot with two object (one for the time and the
other for the date).
Thanks for the answer.

[Matplotlib-users] Plot data with specified time (hour, minute, second)
Hello I'd like to know wether Matplotlib can display data with an x axis based on day, hour, minute and seconds. I found some example and tutorial that shows that this can be done for year, month and day but not for hour, minute, seconds. It looks like matplotlib use the python type date and generate a list of date within a range (at least in the tutorials). I'd like to do the same thing but with customized date and time for each of my points. So my questions would be : can the plot function display some values with a certain time (and if possible date) for each one of the values ? Or, can the plot function use a time object as parameter for x axis ? I also would like to know wether I can use the same type of functionnality as in Gnuplot where you can specify the format of data in input and the data displayed of the x axis. I just guess that the use of the date object replace any kind of setup in data input but anyway...
