代码如下：

成果：
补充知识：python plotly line chart 折线图
# 1 折线图数据 # trace1 - 基本格式 # trace2 - 更多参数 trace1 = go.Scatter( x = x1, y = y2, ) trace2 = go.Scatter( x = x2, y = y2, mode = 'lines', # 模式：lines 线，markers 点。可用“+”相连 name = 'line2', # 折线名，显示于图例 connectgaps = True # 连接缺失点两端 默认False line = dict( color = ('rgb(205, 12, 24)'), # 颜色 width = 4, #线宽 dash = 'dash') # 虚线： dash 一一，dot ···，dashdot 一·一 ) ) # 2 打包数据 data = [trace1,trace2] # 3 格式 layout = dict(title = '折线', xaxis = dict(title = '时间'), # 横轴坐标 yaxis = dict(title = '数量'), # 总轴坐标 legend=dict(x=1.1,y=1) # 图例位置 ) # 4 打包数据+格式 fig = dict(data=data, layout=layout) # 5 画图 py.iplot(fig, filename='styled-line')
