How to plot 3D interactive stem plot in plotly

[Bibu]

I tried to do a 3D scatter plot with driplines and a projection onto the X-Y plane using Plotly Python. Could anyone tell me how to do this? Thanks!

HI @Bibu welcome to the forums.

Are you referring to something like this?

import plotly.graph_objects as go

fig = go.Figure(
    data=go.Scatter3d(
        x=[1,2,3], 
        y=[1,2,3], 
        z=[1,2,3],
        mode='markers+lines', 
        projection={
            'z':{'show':True}
        }
    )
)
fig.show()

This is an example of 3d stem plot:

import numpy as np
import plotly.graph_objects as go

nx=5
ny=6
hmax=7
xl = np.linspace(2,18, nx)
yl= np.linspace(0, 14, ny)
x, y = np.meshgrid(xl,yl)

z= hmax*np.random.rand(nx*ny)
stemsx = []
stemsy = []
stemsz = []
for xs, ys in zip(x.flatten(), y.flatten()):
    stemsx.extend([xs, xs, None])
    stemsy.extend([ys, ys, None])

for zs in z:
    stemsz.extend([0, zs, None])

fig= go.Figure(go.Scatter3d(x=stemsx, y=stemsy, z=stemsz, mode= "lines", 
                            line_width=2, line_color="RoyalBlue"))
fig.add_trace(go.Scatter3d(x=x.flatten(), y=y.flatten(), z=z, mode="markers", 
                           marker_size=5, 
                           marker_color="RoyalBlue"))
fig.update_layout(
                  width=600, height=600,
                  scene_aspectmode="data", scene_camera_eye=dict(x=2, y=2, z=1), 
                  showlegend=False)
