Python 使用plotly绘制气泡图

我正在使用plotly在气泡图中绘制一些数据。我已经编写了以下代码：（基于）

我试图在x轴上绘制

output['mean']

，在y轴上绘制

output['count']

。我想在

输出['total']上绘制大小。

运行时，会收到以下错误：

Traceback (most recent call last):
  File "..data.py", line 45, in <module>
    plot_url = py.plot_mpl(data, filename='mpl-7d-bubble')
  File "...anaconda/lib/python3.5/site-packages/plotly/plotly/plotly.py", line 307, in plot_mpl
    fig = tools.mpl_to_plotly(fig, resize=resize, strip_style=strip_style)
  File ".../anaconda/lib/python3.5/site-packages/plotly/tools.py", line 507, in mpl_to_plotly
    matplotlylib.Exporter(renderer).run(fig)
  File ".../anaconda/lib/python3.5/site-packages/plotly/matplotlylib/mplexporter/exporter.py", line 45, in run
    fig.savefig(io.BytesIO(), format='png', dpi=fig.dpi)
AttributeError: 'list' object has no attribute 'savefig'

有两个小问题阻碍了你理解情节

• plotly希望

  data

  成为

  plotly.graph\u objs.data

  对象

  data = go.Data([trace0])
  

• 您的尺寸标记太大，您需要将其最小化到合理的程度

  size=[i / 100 for i in output['total']]

请打印output@eyllanesc对不起，打印什么输出？您在output['mean']@eyllanesc中使用的输出变量已打印。输出变量是dataframe吗？

size=[i / 100 for i in output['total']]
