Can I pass positions (x,y) of nodes as arguments?

Hello Mohit,

Thanks for the code.
I needed to know if node positions can be passed as arguments to the network.

Thanks and Regards,
Sheena :)

Hey @shina181 yes it is possible. You need to do two things,

• Fix the nodes by modifying the vis_opts. Example below

# define vis options
vis_opts = {'height': '600px', # change height
            'interaction':{'hover': True}, # turn on-off the hover 
            'nodes': {'fixed': {'x': True, 'y': True}}}

• Add two columns in the node_df named x and y with their respective positions. Example below,

Let me know incase of any issue 👋

Thanks Mohit ! I will try it out :)

Hi Mohit !
I tried what you suggested and it worked for the nodes. But for some reason now my edges are not visible in the final plot:

Here is a snippet of my code:

import pandas as pd
from jaal import Jaal

network_df=pd.read_csv('./network_df.csv', sep=',')
network_df.columns=['from', 'to', 'weight']
edge_df=network_df[network_df.weight!= 0.0000]
node_df=pd.read_csv('./nodes_3.csv', sep=',')
node_df.columns=['id', 'x', 'y']

app= Jaal(edge_df,node_df).plot(vis_opts={'height': '600px', # change height
                                      'edges': {'dashes':True, 'color': 'red',
                                                },
                                      'nodes': {'icon': {'size':20,'color':'#fadadd'}, 'shape':'icon',
                                                'fixed': {'x': True, 'y': True},
                                                'font':{'size':4},
                                                },
                                      'interaction':{'hover': False}, # turn on-off the hover
                                      'physics':{'stabilization':{'iterations': 2}},
                                        },
                                )

server = app.server

I also tried using edges.hidden: False. But still edges don't show up.

Hey @shina181 it is working for me.

Here is my setting.

# define vis options
vis_opts = {'height': '600px', # change height
            'interaction':{'hover': True}, # turn on-off the hover 
            'nodes': {'fixed': {'x': True, 'y': True}}} 

Maybe you need to spread the x and y positions (I have mine between 1 and 1000).

Okay. Will try that and get back. Thanks :)
