Question

Can we plot another layer of plot over a visualization using plotly through python.?

I am trying to join two points over a bubble chart.

Answer 1

You should be aware of the concept of traces, where we can place two types of charts in the same graph. To see the concept in action refer Multiple Chart Types in Same Graph . Just as a starting point please refer the below code snippet which does what you want.

from plotly.offline import download_plotlyjs, init_notebook_mode, plot, iplot
import plotly.graph_objs as go
from datetime import datetime
init_notebook_mode(connected=True)

trace0 = go.Scatter(
    x=[1, 2, 3, 4],
    y=[10, 11, 12, 13],
    mode='markers',
    marker=dict(
        size=[40, 60, 80, 100],
    )
)
trace1 = go.Scatter(
    x = [1, 2, 3, 4],
    y = [10, 11, 12, 13],
    line = dict(
        color = ('rgb(22, 96, 167)'),
        width = 4,
        dash = 'line')
)

data = [trace0, trace1]
iplot(data, filename='bubblechart-size')

The line that you require can also be generated using plotly shapes. Please read more about this here
