Hi Gabriele, Matplotlib currently does not do this. The problem, as I understand it (and there are others on this list that may correct me), is that there is a lot of information that needs to be written into the prologue at the beginning of the file, like font information. This makes it difficult to append to an existing file, since each page description could require different information in the prologue. As an alternative, you could create multiple eps files. In the process, you could write a script that generates a simple latex document and embeds your eps files. Then you could convert that into PS. There are examples of this in "Python Scripting for Computational Science" by Hans Petter Langtangen.

I would like to use matplotlib to make a simple client-side
image map for a web page. I have a scatter plot and I would
like mouseovers/clicks to show information about the given
point.
I started with the webapp_demo.py from the most recent
release (0.80). There was a small bug
% python webapp_demo.py
Traceback (most recent call last):
File "webapp_demo.py", line 87, in ?
make_fig()
File "webapp_demo.py", line 64, in make_fig
x = nx.rand(100)
AttributeError: 'module' object has no attribute 'rand'
Here's my bandage hack
import random
def rand(n):
return nx.array([random.random() for i in range(n)])
nx.rand = rand
I then added some code after the PNG is written which
generates an basic html file from the coordinates using
what I thought was the correct transformation from
data space to image space.
canvas.print_figure('webapp.png', dpi=150)
f = open("webapp.html", "w")
f.write('''<HTML><BODY><img src="webapp.png" ismap usemap="#plot">
<map name="plot">
''')
t = c.get_transform()
xys = t.seq_xy_tups(c.get_verts())
for i, xy in enumerate(xys):
f.write('<area shape="circle" coords="%d,%d,2" href="%d">\n' %
(xy[0], xy[1], i))
f.write("</map>\n</html>")
The HTML output starts with the following
<HTML><BODY><img src="webapp.png" ismap usemap="#plot">
<map name="plot">
<area shape="circle" coords="393,286,2" href="0">
<area shape="circle" coords="381,285,2" href="1">
<area shape="circle" coords="222,271,2" href="2">
<area shape="circle" coords="238,300,2" href="3">
There are two things wrong with the code. First, the
transformed coordinates aren't at the same scale as
the generated PNG. The PNG size depends on the dpi
setting but the x/y coordinates aren't affected by
that setting.
Second, I think I have the y direction swapped. Where
do I get the current image size, and for that matter
how do I set the output image size?

Hi All, I think I found a solution for dates.py which could work for everyone. Instead of hardcoding the encoding I "import locale" and get the default encoding from it. I have tested it on both Win XP and 2000 and it works for me, i.e. in English locale I get "Dec" and in French locale I get "déc." etc. without the correction I would get a graphic sign for the "é". To test just use "locale.setlocale(locale.LC_ALL, 'fr')" Just noticed that "avr" is not correctly aligned with the other month, but that's for another day. The only two changes needed to dates.py are: import locale and change return dt.strftime(fmt) to return unicode(dt.strftime(fmt), locale.getpreferredencoding()) Best regards Werner Werner F.

Hi, I'm new to matplotlib, I'm trying to save a series of plots in a single postscript files. Is that possible? I'm able to save each single plot in a different file using savefig, but I'd like my script to save the plots in a single ps file with more pages. Is there anyway to open a ps file, send the output of the plot() command to it and close it as the script ends? Thanx Cheers Gabriele
