Matplotlib绘制散点图与条形图

绘制散点图

# 绘制散点图from matplotlib import pyplot as pltfrom matplotlib import font_manager# C:\Windwos\Fonts\msyh.ttcmy_font = font_manager.FontProperties(fname="C:\Windows\Fonts\simhei.ttf")y_3 = [11, 17, 16, 11, 12, 11, 12, 6, 6, 7, 8, 9, 12, 15, 14, 17,       18, 21, 16, 17, 20, 14, 15, 15, 15, 19, 21, 22, 22, 22, 23]y_10 = [26, 26, 28, 19, 21, 17, 16, 19, 18, 20, 20, 19, 22, 23, 17,        20, 21, 20, 22, 15, 11, 15, 5, 13, 17, 10, 11, 13, 12, 13, 6]x_3 = range(0, 31)x_10 = range(40, 71)# 这是图形大小plt.figure(figsize=(20, 8), dpi=80)# 使用scatter绘制散点图plt.scatter(x_3, y_3, label="3月份")plt.scatter(x_10, y_10, label="10月份")# 调整X的刻度_x = list(x_3) + list(x_10)_xtick_lables = ["3月{0}日".format(i) for i in x_3]_xtick_lables += ["10月{0}日".format(i) for i in x_10]plt.xticks(_x[::3], _xtick_lables[::3], fontproperties=my_font, rotation=45)# 添加图例plt.legend(loc="upper left", prop=my_font)# 添加标题plt.xlabel("月份", fontproperties=my_font)plt.ylabel("温度", fontproperties=my_font)plt.title("3月份与10月份温度对比散点图", fontproperties=my_font)# 展示plt.show()

绘制条形图

# 绘制条形图from matplotlib import pyplot as pltfrom matplotlib import font_manager# 设置字体my_font = font_manager.FontProperties(fname="C:\Windows\Fonts\simhei.ttf")a = [    "战狼2", "速度与激情8", "功夫瑜伽", "西游伏妖篇", "变形金刚5：最后的骑士", "摔跤吧！爸爸", "加勒比海盗5：死无对证", "金刚：骷髅岛", "极限特工：终极回归", "生化危机6：终章", "乘风破浪", "神偷奶爸3", "智取威虎山", "大闹天竺", "金刚狼3：殊死一战", "蜘蛛侠：英雄归来", "悟空传", "银河护卫队2", "情圣", "新木乃伊"]b = [    56.01, 26.94, 17.53, 16.49, 15.45, 12.96, 11.8, 11.61, 11.28,    11.12, 10.49, 10.3, 8.75, 7.55, 7.32, 6.99, 6.88, 6.86, 6.58, 6.23]# 调整图形大小plt.figure(figsize=(16, 6), dpi=90)# 绘制图形# plt.bar是绘制树状条形图plt.barh(range(len(a)), b, height=0.4, color="red")# 设置Y轴刻度plt.yticks(range(len(a)), a, fontproperties=my_font)# 设置网格，para:alpha 透明度plt.grid(alpha=0.4)# 设置标签plt.xlabel("票房 单位：亿元", fontproperties=my_font)plt.ylabel("电影", fontproperties=my_font)plt.title("电影票房统计", fontproperties=my_font)# 展示plt.show()
