一、使用 pyecharts 模块绘制折线图
1、折线图绘制过程
首先 , 导入 折线图 Line 对象 , 该类定义在 pyecharts.charts 中 ;
# 导入 pyecharts 模块中的 折线图 Line 对象
from pyecharts.charts import Line
然后 , 创建 Line 类型 折线图 对象 ;
# 创建 折线图 对象
line = Line()
再后 , 分别 设置 x 轴 和 y 轴 数据 ;
# 设置 x 轴数据
line.add_xaxis(["西城", "东城", "海淀", "朝阳", "昌平"])# 设置 y 轴数据
line.add_yaxis("清北录取人数", [105, 28, 215, 16, 1])
最后 , 调用 Line 对象的 render() 函数 , 生成图标 ;
# 生成图表
line.render()
生成的 折线图 图表 , 会以 HTML 页面的形式展示出来 ;
生成的 HTML 文件名称为 render.html ;
2、完整代码示例
代码示例 :

"""# 导入 pyecharts 模块中的 折线图 Line 对象
from pyecharts.charts import Line# 创建 折线图 对象
line = Line()# 设置 x 轴数据
line.add_xaxis(["西城", "东城", "海淀", "朝阳", "昌平"])# 设置 y 轴数据
line.add_yaxis("清北录取人数", [105, 28, 215, 16, 1])# 生成图表
line.render()在 该 python 源码的同目录中 , 生成 render.html ,
生成的 html 如下 :
