我有下面的代碼，從畫廊居中標題
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.ticker import NullFormatter
from itertools import groupby
import matplotlib.pyplot as plt
import numpy
#fig = plt.figure(figsize=(13, 12))
files = ("file1","file2")
place = (1,2)
print files
print place
plt.bone()
for f in zip(files,place):
print "file", f
# would like the two below each other, don't know how, so i clear
plt.clf()
# data comes from the files normally
x = np.random.randn(1000)
y = np.random.randn(1000)
z = np.random.randn(100)
nullfmt = NullFormatter() # no labels
# definitions for the axes
left, width = 0.1, 0.65
bottom, height = 0.1, 0.65
bottom_h = left_h = left+width+0.02
rect_scatter = [left, bottom, width, height]
rect_histx = [left, bottom_h, width, 0.2]
rect_histy = [left_h, bottom, 0.2, height]
# start with a rectangular Figure
plt.figure(1, figsize=(8,8))
plt.xlabel('$^{13}$C (ppm)')
plt.ylabel('$^{15}$H (ppm)')
axScatter = plt.axes(rect_scatter)
axHistx = plt.axes(rect_histx)
axHisty = plt.axes(rect_histy)
# no labelsfor the histgrams
axHistx.xaxis.set_major_formatter(nullfmt)
axHisty.yaxis.set_major_formatter(nullfmt)
# the scatter plot:
#axScatter.scatter(x, y)
axScatter.scatter(numpy.float64(x),numpy.float64(y), c=numpy.float64(z),lw=0.1,s=5)
# now determine nice limits by hand:
binwidth = 0.25
xymax = np.max([np.max(np.fabs(x)), np.max(np.fabs(y))])
lim = (int(xymax/binwidth) + 1) * binwidth
axScatter.set_xlim((min(x), max(x)+binwidth))
axScatter.set_ylim((min(y), max(y)+binwidth))
#axScatter.set_ylim((-lim, lim))
binwidth = (max(x) - min(x))/20
bins = np.arange(min(x), max(x) + binwidth, binwidth)
axHistx.hist(x, bins=bins)
binwidth = (max(y) - min(y))/20
bins = np.arange(min(y), max(y) + binwidth, binwidth)
axHisty.hist(y, bins=bins, orientation='horizontal')
axHistx.set_xlim(axScatter.get_xlim())
axHisty.set_ylim(axScatter.get_ylim())
plt.savefig(f[0]+"out_hist.png", format='png',dpi=1200)
plt.savefig(f[0]+"out_hist.svg", format='svg')
撕開此代碼給我： 
但是，我不知道這個框架的背景來自。而且我想讓我的標題集中在情節上，而不是整個事情。最後，我不能在我的生活中以簡單的JPG格式將這些情節置於彼此之下。我如何解決這些問題？
