Title: Signature.html




It's very difficult to tell. I've tried it. 
    fLocation=Frame(master)
    fLocation.pack(side=LEFT)
I need to size the fLocation frame to make it big. As it is, it must be
giving the smallest possible size. 

I tried this
        fLocation.pack(expand=YES,fill=BOTH,side=TOP)

Have a good vacation ...

Other common ways this is done include:

This works well if one copy is to be used the entire time the

and

def get_todo(todo=None):

Both the above allow you to pass in a starting todo dict, so you could

Title: Signature.html




Correction. The size of the button is interfering with positioning
here. I'm pretty sure that if the frame size is set to a large value,
width, in particular, then the entry of four columns will not be
adjusted to the left, but will appear centered. The point is that I
want this line left justified. If I put a similar frame above it, the
lower one gets centered.

Re: [Tutor] plotting with python

2009-03-27 Thread greg whittier

matplotlib and pylab are two APIs to the same library.  Using
matplotlib is a more object-oriented, pythonic API.  pylab is modeled
after the Matlab plotting functions to make it easier for those coming
from that environment.

There's a matplotlib mailing list and you can often figure out what
you need from perusing the examples and the thumbnail gallery.  In
your case, I think
http://matplotlib.sourceforge.net/examples/api/two_scales.html is what
you want.

IIUC, pylab is part of matplotlib. It provides a simplified,
functional (not object-oriented) interface to matplotlib. Using
matplotlib directly gives you more control over the result.

> iii) can some kindly show me an example of ploting multy Y axes plot, ie NXY.
Take a look at the gallery for something similar to what you want.
Clicking on a gallery image will show you a larger image and the code
that created it.

[Tutor] plotting with python

2009-03-27 Thread Bala subramanian

Friends,
I am not sure if this forum is appropriate to ask question about a
particular package. After getting suggestions from some of you for python
based plotting, I have just started with matplotlib. I am bit confused with
the relation between matplotlib and pylab.

In the matplotlib homepage, example plots are shown with both *
matplotlib.pyplot* and* pylab*. Inaddition within matplotlib, there is a
module called *matplotlib.pylab*

i) matplotlib and pylab -> both are same or different modules ?. Is there
any advantage of using one over the other ?

ii) Is it like i can plot the graphs with both matplotlib and pylab ?

iii) can some kindly show me an example of ploting multy Y axes plot, ie
NXY.

Thanks in advance,
Bala
