odd -- it works fine for me -- are you subscribed?

I tried posting this to numpy, but my posts never show up.  So, I was hoping
someone here might be able to help me.

I have two arrays that are different sizes and i would like to be able
to add them for plotting.

If I have an array a and b,

[[1 2 3 4 5 6 7 8 9]
 [1 2 3 4 5 6 7 8 9]
 [1 2 3 4 5 6 7 8 9]
 [1 2 3 4 5 6 7 8 9]
 [1 2 3 4 5 6 7 8 9]
 [1 2 3 4 5 6 7 8 9]
 [1 2 3 4 5 6 7 8 9]
 [1 2 3 4 5 6 7 8 9]
 [1 2 3 4 5 6 7 8 9]
 [1 2 3 4 5 6 7 8 9]]

[[0 0 0 0 0]
 [0 3 3 3 0]
 [0 3 3 3 0]
 [0 3 3 3 0]
 [0 0 0 0 0]]

but I would like to change b to look like this,

[[0 0 0 0 0 0 0 0 0]
 [0 0 0 0 0 0 0 0 0]
 [0 0 3 3 3 3 3 0 0]
 [0 0 3 3 3 3 3 0 0]
 [0 0 3 3 3 3 3 0 0]
 [0 0 3 3 3 3 3 0 0]
 [0 0 3 3 3 3 3 0 0]
 [0 0 3 3 3 3 3 0 0]
 [0 0 0 0 0 0 0 0 0]
 [0 0 0 0 0 0 0 0 0]]

so I can get the sum of a and b.

My data will not be regular like these. I have a 400x60 array with
irregular data that I would like as a 400x400 array.  Does anybody
know of an easy way to accomplish this?

My fault.  that last error was because I re-installed matplotlib and forgot 
to "re-change" the backend to TkAgg.
Sorry.  Everything seems to be working again now (although a bit slower).
Kurt

Looks like your latest compile includes the full-res data.
Kurt

Well, installing the highres data into the 'data' directory didn't help.
Kurt

Jeff, Got it and it seemed to install.

Well... as luck would have it, I still have a problem.  I think I know what 
is causing it, though.  I was using the high-res data, and the "upgrade" 
nukes that data.  Here's the message I'm getting along with the code 
snippet, just to make sure I'm on the right track for a solution:

Exception in Tkinter callback

line 100, in populate_location_map

Code Snippet:
    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-0.99\examples\citiesx020', 
'states', drawbounds=True)


Any hints on what to do now that I am downloading the fullres?
Regards,
Kurt

HI , thank you very much for the quick reply, i have an older version (which is not up to me
upgrade) so the subplots_adjust worked just fine. Thanks again.
bye for now

First of all I cannot confirm your observation with the online version of the 
example at
http://matplotlib.sourceforge.net/examples/pylab/date_demo_convert.py

Maybe the function "fig.autofmt_xdate" is not included in your version of the 
example. 
With that function you have many possibilities to change the x-date-format, 
e.g.  fig.autofmt_xdate(bottom=0.3, rotation=45)
or you can extend the space between the axes and the border of the figure  
yourself using
subplots_adjust(bottom=0.2)

best regards
Matthias

What you are asking for is controlled by the "subplots_adjust" parameter

  fig.subplots_adjust(bottom=0.2)

but for dates in particular we have a helper function which:

  * adjusts the bottom
  * rotates the ticks
  * right aligns them

Try fig.autofmt_xdate() with recent matplotlib releases.

JD

Hi all,
i have a plot on which the x axix has timestamps info; i would like to control the size
of the edge or border (not sure whta is the proper word) so the there is enough space between
the real plot and the outer border so that the x labels are not cut out. I rotate the xlabel also
but still i don't have enough space; how do i control that feature? Even in one of the demo examples
i see the same problem, example in  date_demo_convert.py where you can't see the x full lable.

Thank all you much 

Margherita

Hi,

Thanks for the tips, I'll try that :)

Hi Matthieu,

I'm not sure if somebody else already answered to your question and I don't 
know the best way to achieve what you need, but I suggest the following 
work-around:

scatter(x, x**2.4, marker='s', color='r', s=25, label="_")
# with no label

plot([0], [0], ls='', marker='s', color='r', ms=5, mew=0, label="my label")
# plot somewhere outside the shown axis with the preferred label

legend()

Best regards
Matthias
