python(数据分析)第4天：绘制网格

import matplotlib.pyplot as plt
import random
import matplotlib
from matplotlib import cycler
from matplotlib.font_manager import FontProperties# 支持的中文字体
font1 = FontProperties(fname=r"c:windows")y = [1, 2, 3, 2, 4, 1, 4, 3, 6, 3, 1, 2, 3, 4, 6, 7, 9, 6, 7, 4]
x = range(11, 31)plt.figure(figsize=(20, 8))plt.plot(x, y)# 调整x轴上的字符串刻度
_x_ticks = ["{}岁".format(i) for i in x ]
icks(x, _x_ticks, fontproperties=font1)
# 绘制网格
id()
plt.show()

调整y轴更密集一点

import matplotlib.pyplot as plt
import random
import matplotlib
from matplotlib import cycler
from matplotlib.font_manager import FontProperties# 支持的中文字体
font1 = FontProperties(fname=r"c:windows")y = [1, 2, 3, 2, 4, 1, 4, 3, 6, 3, 1, 2, 3, 4, 6, 7, 9, 6, 7, 4]
x = range(11, 31)plt.figure(figsize=(20, 8))plt.plot(x, y)# 调整x轴上的字符串刻度
_x_ticks = ["{}岁".format(i) for i in x ]
icks(x, _x_ticks, fontproperties=icks(range(0,9))# 绘制网格
id()plt.show()

设置网格透明度 id(alpha=0.2)

import matplotlib.pyplot as plt
import random
import matplotlib
from matplotlib import cycler
from matplotlib.font_manager import FontProperties# 支持的中文字体
font1 = FontProperties(fname=r"c:windows")y = [1, 2, 3, 2, 4, 1, 4, 3, 6, 3, 1, 2, 3, 4, 6, 7, 9, 6, 7, 4]
x = range(11, 31)plt.figure(figsize=(20, 8))plt.plot(x, y)# 调整x轴上的字符串刻度
_x_ticks = ["{}岁".format(i) for i in x]
icks(x, _x_ticks, fontproperties=icks(range(0, 14))# 绘制网格
id(alpha=0.2)plt.show()
