Im developing a financial python/wx/sqlite and the client requested me a chart. I first thought about using win32com to call excel but didnt sound so clean to me. I googled a little and found matplot. Seems really great even becouse it could be embedded on WX applications. But since im out of time i just used the simplest example without embedding anything:
from pylab import *
class VButler(wx.Frame):
(…)
def first_chart (self,ticks):
display = self.load_indicatorVol(ticks)
colors=[‘ro’,‘bo’,‘go’,‘yo’,‘rs’,‘bs’,‘gs’,‘ys’]
for row in display:
try:
cor=colors.pop(0)
except:
colors=['rx','bx','gx','yx','rv','bv','gv','yv']
cor=colors.pop(0)
plot([float(row[2])],[float(row[3])],cor)
text(float(row[2]),float(row[3]),row[0])
axis([0,10,0,25])
show()
When i tryed to print using printing_in_wx.py i couldnt. It would only print a part of the graphic, if i tryed to preview the print it would show me a blank page. Ctrl+c had a problem since event.KeyCode is not a function and was called like one, but fixed that it would copy the image to clipboard OK.
My boss is requesting me this software as soon as yesterday so i gave him the option of first saving it as a PNG and then print… When i tryed to build a py2exe i got some problems…
My Setup Code
VolatilityButler = Target(
# used for the versioninfo resource
description = "VolatilityButler",
version = "1.2.1",
company_name = "Sala 1 / La Colina",
name = "VolatilityButler",
# what to build
script = "vol_butler.py",
other_resources = [(RT_MANIFEST, 1, manifest_template % dict(prog="VolatilityButler")),],
icon_resources = [(1, "butler.ico
")],
dest_base = “VolatilityButler”)
setup(
options = {“py2exe”: {“compressed”: 1,
“optimize”: 2,
“ascii”: 1,
"bundle_files": 1}},
zipfile = None,
windows = [VolatilityButler],
)
#Error after running it
The following modules appear to be missing
[‘FFT’, ‘LinearAlgebra’, ‘MA’, ‘MLab’, ‘Matrix’, ‘Numeric’, ‘Pyrex’, ’
Pyrex.Compiler’, ‘_curses’, ‘backends.draw_if_interactive’,‘backends.new_figure_manager’,…]
it was alot of modules not found and when i tryed to run the exe
Traceback (most recent call last):

i looked at some setup.py examples, but they are from python 2.3 and using a ‘share’ folder that i dont have in my Python2.5 folder. But i tryed to make it like the example.
data = glob.glob(‘C:\Python25\Lib\site-packages\matplotlib*’)
setup(
options = {“py2exe”: {“compressed”: 1,
“optimize”: 2,
“ascii”: 1,
“bundle_files”: 1}},
zipfile = None,
windows = [VolatilityButler],
data_files=[(“matplotlibdata”,data)],
)
and the error while running the setup:
*** copy data files ***
error: can’t copy ‘C:\Python25\Lib\site-packages\matplotlib\backends’: doesn’t exist or not a regular file
