matplotlib 好像有自己的图形库? 能跟wxpython结合吗?

我用pil可以实现饼图


import sys,Image, ImageDraw, ImageFile, re,ImageFont
font='c:\\windows\\fonts\\arial.ttf'
f=open(sys.argv[1],'r')
im=Image.new("RGB",[800,500],color="white")
draw=ImageDraw.Draw(im)
myfont=ImageFont.truetype(font,16)
draw.setfont(myfont)
totalangle=360
currentangle=0
totalnum=0
for line in f:
	value=int(re.split(",",line)[1][:-1])
	totalnum+=value
f.seek(0)
color=['red','purple','magenta','firebrick','salmon','lightseagreen','lightskyblue','gold','black'
\
	,'lightslategray','lightsteelblue','lightyellow']
for line in f:
	percent=float(re.split(",",line)[1][:-1])/float(totalnum)
	degree=int(percent*360)
	draw.pieslice((50,50,400,400),currentangle,(currentangle+degree),fill=color[i])
	currentangle+=degree
	totalangle-=degree
im.show()
