Plotly scatter plots pie chart combo

📊 Plotly Python

Hi

Is it possible to replicate this scatter plot / pie chart combo in python plotly?

I essentially to build a scatter plot with variable size pie charts for each “bubble” on the scatter plot

Thanks

Hey @gtg592v ,

I think it is possible.

import plotly.graph_objects as go
import math

def scatter_pie(radius, x, y, sectors):
   
    colors = ["red","green","blue"]
    angles = [360 * val / 100 for val in sectors]
    angles = [math.radians(x) for x in angles]
   
    nop = 100 #number of points

    start_angle = 0
    
    pie_segments = []
    
    for i,j in zip(angles,colors):

        end_angle = start_angle + i

        d_theta = (end_angle - start_angle) / (nop - 1)

        theta = [start_angle + i * d_theta for i in range(nop)]
        x_segment = [x + radius * math.cos(t) for t in theta]
        y_segment = [y + radius * math.sin(t) for t in theta]

        # Add the center coordinates to close the circle segment
        x_segment.append(x)
        y_segment.append(y)


        trace = go.Scatter(x=x_segment,
                           y=y_segment,
                           mode='lines',
                           fill="toself",
                           fillcolor=j,
                           line=dict(color='blue', width=2)
                           )

        pie_segments.append(trace)
        start_angle = end_angle
        
    return pie_segments



pie1 =  scatter_pie(2,0,0,[20,30,50])
pie2 =  scatter_pie(2,3,4,[70,10,20])

fig = go.Figure(pie1+pie2)

fig.update_xaxes(constrain='domain')
fig.update_yaxes(scaleanchor='x')

fig.update_layout(xaxis=dict(range=[-8, 8]),
                  yaxis=dict(range=[-8, 8])
                  )

fig.show()
