For independent reasons, I already did away with numeric limits in
_transforms.cpp a couple of weeks ago and these changes are in CVS.
If one of you would be willing to try and compile CVS against gcc
2.95.2, I would be interested to hear how it works, and will be happy
to make any required changes.

Thanks,
JDH

I just released numarray-1.0 and wanted to give you a heads up in case
you miss it in the release notes:   numarray-1.0 needs a new windows
binary for matplotlib which is now up on source forge here:

http://prdownloads.sourceforge.net/matplotlib/matplotlib-0.54.2-numarray1.0.win32-py2.3.exe?download

Likewise, UNIX and Mac users that want to use numarray-1.0 need to
reinstall matplotlib (make sure you delete the matplotlib build
directory).

I attached the numarray-1.0 release notes in case you're interested...

Regards,
Todd

One place to look is http://matplotlib.sf.net/matlab_interface.html
and the help for the plotting commands listed there.  If this case,
you want to see the help for the figure command:

    figure(num = 1, figsize=(8, 6), dpi=80, facecolor='w', edgecolor='k')


    Create a new figure and return a handle to it

    If figure(num) already exists, make it active and return the
    handle to it.

      figure(1)

    figsize - width in height x inches; defaults to rc figure.figsize
    dpi     - resolution; defaults to rc figure.dpi
    facecolor - the background color; defaults to rc figure.facecolor
    edgecolor - the border color; defaults to rc figure.edgecolor


One day, hopefully in the not too distant future, I'll have a user's
guide.

Thanks - looking at that snippet made me realize I was switched around - =
I was setting minx =3D DBL_MIN and maxx =3D DBL_MAX.

With that fixed, it works fine. =20

I agree this might be a good thing to change in CVS, since this is the =
only thing tripping up a clean compile with gcc 2.95.

Hi Trevor,
I just substituted like this

  if (ignore) {
    minx = 1e+308; //orig: std::numeric_limits<double>::max();
    maxx = 1e-308; //orig: std::numeric_limits<double>::min();
  }

and didn't have any problem. 
I running debian, where 2.95 is still the "standard". Maybe this could be 
changed in CVS - just for one more year or so ;-)

Cheers,
Sebastian Haase

Hi,

I'm trying to compile matplotlib-0.54.2 on FreeBSD 4.8, using =
gcc-2.95.3. =20

In _transforms.cpp, std::numeric_limits<double>::max() and ::min() =
aren't present, so I've tried replacing them with #include<float.h>, =
DBL_MIN and DBL_MAX.

However, now an error is being raised in ticker.py:get_locator(), line =
638:

            try: ld =3D math.log10(d)
            except OverflowError:
                print >> sys.stderr, 'AutoLocator illegal dataInterval =
range %s; returning NullLocator'%d
                return NullLocator()


I.e., the OverflowError is occurring.  I'm assuming this is cause of the =
change I made; I can run the same test script under Windows with no =
problems (but the test script is a little too involved for me to paste =
here).

Does anyone have ideas on a better workaround?


Trevor

another newbie question. BTW I am learning where to find documentation.
Most of this stuff isn't in the documentation per se, but in the class
library, but please bare with me. 

I am aving big troubles setting figure sizes.

In a plot command. I have tried
plot(...,figsize=(6,8)) and
plot(...,figsize_inches=(6,8)
set(gcf(),'figsize',(6,8))
set(gcf(),'figsize_inches',(6,8))

none work for me. OK I'm stumped, what's the right way.

thanks,
Danny

Hi Danny,

You may want to take a look at
http://matplotlib.sf.net/tutorial.html#lineprops which shows several
ways of setting linewidths and other line properties.  In addition to
the way Gary showed, you can also use keyword arguments

plot(x ,y, linewidth=2.0)

The default linewidth is controlled by the lines.linewidth property in
your matplotlibrc file -- see http://matplotlib.sf.net/.matplotlibrc.

JDH

Here's a snippet done on errorbars which should point you in the right direction:

l1,e1=errorbar(m, t, [tN, tP], fmt='rD-', ecolor=(.5,.5,.5), capsize=3)
set(e1,"linewidth",1,"markeredgewidth",1)
set(l1,"linewidth",2,"markersize",5,"markerfacecolor",'k',"markeredgecolor",'k')
