# 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
```
![自定义Rc示例](https://matplotlib.org/_images/sphx_glr_customize_rc_001.png)
```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()
```
