plotly数据填充的交互面积图，Python

import plotly as py
import plotly.graph_objs as go
import numpy as np

if __name__ == '__main__':
    count = 20
    ax = [a for a in range(count)]
    y1 = np.random.random(count) + 1
    print(y1)
    y2 = np.random.random(count) + 2
    print(y2)

    trace1 = go.Scatter(
        x=ax,
        y=y1,
        fill='tonexty',
        mode='none',  # 无边界线
        name="甲"
    )
    trace2 = go.Scatter(
        x=ax,
        y=y2,
        fill='tozeroy',
        mode='none',  # 无边界线
        name="乙"
    )

    data = [trace1, trace2]

    layout = dict(title='曲线',
                  xaxis=dict(title='时间'),
                  yaxis=dict(title='对比参照'),
                  )
    fig = dict(data=data, layout=layout)
    py.offline.plot(fig, filename='fig.html')
