# 自定义Rc
|
||
|
||
我不是想在这里做一个好看的人物，而只是为了展示一些动态定制rc params的例子
|
||
|
||
如果您希望以交互方式工作，并且需要为图形创建不同的默认设置（例如，一组用于发布的默认设置，一组用于交互式探索），您可能希望在自定义模块中定义一些设置默认值的函数， 例如，：
|
||
|
||
```python
|
||
def set_pub():
|
||
rc('font', weight='bold') # bold fonts are easier to see
|
||
rc('tick', labelsize=15) # tick labels bigger
|
||
rc('lines', lw=1, color='k') # thicker black lines
|
||
rc('grid', c='0.5', ls='-', lw=0.5) # solid gray grid lines
|
||
rc('savefig', dpi=300) # higher res outputs
|
||
```
|
||
|
||
然后，当您以交互方式工作时，您只需要：
|
||
|
||
```python
|
||
>>> set_pub()
|
||
>>> subplot(111)
|
||
>>> plot([1,2,3])
|
||
>>> savefig('myfig')
|
||
>>> rcdefaults() # restore the defaults
|
||
```
|
||
|
||
|
||
|
||
```python
|
||
import matplotlib.pyplot as plt
|
||
|
||
plt.subplot(311)
|
||
plt.plot([1, 2, 3])
|
||
|
||
# the axes attributes need to be set before the call to subplot
|
||
plt.rc('font', weight='bold')
|
||
plt.rc('xtick.major', size=5, pad=7)
|
||
plt.rc('xtick', labelsize=15)
|
||
|
||
# using aliases for color, linestyle and linewidth; gray, solid, thick
|
||
plt.rc('grid', c='0.5', ls='-', lw=5)
|
||
plt.rc('lines', lw=2, color='g')
|
||
plt.subplot(312)
|
||
|
||
plt.plot([1, 2, 3])
|
||
plt.grid(True)
|
||
|
||
plt.rcdefaults()
|
||
plt.subplot(313)
|
||
plt.plot([1, 2, 3])
|
||
plt.grid(True)
|
||
plt.show()
|
||
```
