# ggplot样式表
|
||
|
||
此示例演示了“ggplot”样式，该样式调整样式以模拟[ggplot](http://ggplot2.org/)（[R](https://www.r-project.org/)的流行绘图包）。
|
||
|
||
这些设置被无耻地从[[1]](https://matplotlib.org/gallery/style_sheets/ggplot.html#id2)窃取(经允许)。

```python
|

import numpy as np
|
||
import matplotlib.pyplot as plt
|
||
|
||
plt.style.use('ggplot')
|
||
|
||
# Fixing random state for reproducibility
|
||
np.random.seed(19680801)
|
||
|
||
fig, axes = plt.subplots(ncols=2, nrows=2)
|
||
ax1, ax2, ax3, ax4 = axes.ravel()
|
||
|
||
# scatter plot (Note: `plt.scatter` doesn't use default colors)
|
||
x, y = np.random.normal(size=(2, 200))
|
||
ax1.plot(x, y, 'o')
|
||
|
||
# sinusoidal lines with colors from default color cycle
|
||
L = 2*np.pi
|
||
x = np.linspace(0, L)
|
||
ncolors = len(plt.rcParams['axes.prop_cycle'])
|
||
shift = np.linspace(0, L, ncolors, endpoint=False)
|
||
for s in shift:
|
||
ax2.plot(x, np.sin(x + s), '-')
|
||
ax2.margins(0)
|
||
|
||
# bar graphs
|
||
x = np.arange(5)
|
||
y1, y2 = np.random.randint(1, 25, size=(2, 5))
|
||
width = 0.25
|
||
ax3.bar(x, y1, width)
|
||
ax3.bar(x + width, y2, width,
|
||
color=list(plt.rcParams['axes.prop_cycle'])[2]['color'])
|
||
ax3.set_xticks(x + width)
|
||
ax3.set_xticklabels(['a', 'b', 'c', 'd', 'e'])
|
||
|
||
# circles with colors from default color cycle
|
||
for i, color in enumerate(plt.rcParams['axes.prop_cycle']):
|
||
xy = np.random.normal(size=2)
|
||
ax4.add_patch(plt.Circle(xy, radius=0.3, color=color['color']))
|
||
ax4.axis('equal')
|
||
ax4.margins(0)
|
||
|
||
plt.show()
|
||
```
