我如何適合長頭銜？

Question

有一個similar question - 但我不能讓解決方案建議在那裏工作。

下面是一個例子情節與長標題：

#!/usr/bin/env python 

import matplotlib 
import matplotlib.pyplot 
import textwrap 

x = [1,2,3] 
y = [4,5,6] 

# initialization: 
fig = matplotlib.pyplot.figure(figsize=(8.0, 5.0)) 

# lines: 
fig.add_subplot(111).plot(x, y) 

# title: 
myTitle = "Some really really long long long title I really really need - and just can't - just can't - make it any - simply any - shorter - at all." 

fig.add_subplot(111).set_title("\n".join(textwrap.wrap(myTitle, 80))) 

# tight: 
(matplotlib.pyplot).tight_layout() 

# saving: 
fig.savefig("fig.png") 

它給出了一個

AttributeError: 'module' object has no attribute 'tight_layout' 

，如果我fig.tight_layout()取代(matplotlib.pyplot).tight_layout()它給：

AttributeError: 'Figure' object has no attribute 'tight_layout' 

所以我的問題是 - 我如何適應情節的標題？

Answer 1

這裏就是我終於用：

#!/usr/bin/env python3 

import matplotlib 
from matplotlib import pyplot as plt 
from textwrap import wrap 

data = range(5) 

fig = plt.figure() 
ax = fig.add_subplot(111) 

ax.plot(data, data) 

title = ax.set_title("\n".join(wrap("Some really really long long long title I really really need - and just can't - just can't - make it any - simply any - shorter - at all.", 60))) 

fig.tight_layout() 
title.set_y(1.05) 
fig.subplots_adjust(top=0.8) 

fig.savefig("1.png") 

Answer 2

一種方式做到這一點是簡單地更改標題的字體大小：

import pylab as plt 

plt.rcParams["axes.titlesize"] = 8 

myTitle = "Some really really long long long title I really really need - and just can't - just can't - make it any - simply any - shorter - at all." 
plt.title(myTitle) 
plt.show() 

在回答您鏈接是涉及添加換行符其他幾個很好的解決方案。甚至有一個automatic solution，根據這個數字調整大小！
