[matplotlib-devel] Numerix in wxmpl

[Christopher B. <Chr...@no...>]

Ken,

I've found Numerix used in wxmpl, but it's been deprecated, so I've 
replaced all the calls with direct numpy calls. However, I can't pretend 
that I've tested well at all -- all I know is that it's working for me. 
In particular, I haven't tested plotit beyond making sure it complies.

I've enclosed a zip archive with my modifications. If you have it in SVN 
somewhere I could give you a diff -- just let me know if I can help further.


Also, I see this a lot in your plotit code:

if not isinstance(x, (np.ndarray, np.ma.masked_array)):

(though you had Numerix equivalent)

What I like to do instead is call:

try:
     x = asarray(x, dtype=np.float)
except ValueError:
     raise your error here...

(and maybe a reshape call, too, to make sure it can be converted into 
that shape)

I  usually don't care if I'm getting an array, as long as it can be 
turned into one...

If you do want to check the type, np.ma is a subclass of ndarray, so:

isinstance(x, np.ndarray)

should do it. That's what I've put in the code for now.

-Chris
