   Thanks @Cedricyf !

   We have a regression on the free Graphistry Hub relating to a bunch of library upgrades yesterday -- are you on Hub or a private server?

   Edit: I see v2.37.23 in the screenshot, so looks like Hub. Will ping when fixed!

   @Cedricyf

   I took a look -- can you try setting graphistry.register(api=3, username='...', password='...') at the top and rerun? This may be an issue around using api=1 or api=2 protocols, which we can help with, but better to use api=3

   Later today, will be releasing a new version of this notebook that is in a more modern style, including explicitly using api=3 features

   Hi @lmeyerov,
   What I have used is api=3 with my username and password. I just tried the new version, the color is still black/white and I used numeric value for the point_color parameter.
   Thank you!

   Hi @Cedricyf I think I see what's happening.

   When passing in a color attribute column, vs using a symbolic encoding, we handle int32 as palettes and int64 as rgb hex values. I'm guessing you are using an unexpected type or value range. You can check what g._nodes.info() shows to see which you are using, and pandas as_type to convert. You can find more examples and the int32 palettes here: https://hub.graphistry.com/docs/api/2/rest/upload/colors/#extendedpalette2

   Let me know how goes!

   ---

   Quick example of both:

   graphistry.register(api=3, username='...', password='...')
   
   g = (graphistry
        .edges(
            pd.DataFrame({
                's': ['a', 'b', 'c'],
                'd': ['b', 'c', 'a']}),
            's', 'd')
        .nodes(
            pd.DataFrame({
                'n': ['a', 'b', 'c'],
                'c32': pd.Series([0, 1, 2], dtype='int32'),
                # format is 0xRRGGBB00
                'c64': pd.Series([0xFF000000, 0x00FF0000, 0x0000FF00], dtype='int64')
            }),
            'n'))
   
   g._nodes.info()

   =>

   <class 'pandas.core.frame.DataFrame'>
   RangeIndex: 3 entries, 0 to 2
   Data columns (total 3 columns):
    #   Column  Non-Null Count  Dtype 
   ---  ------  --------------  ----- 
    0   n       3 non-null      object
    1   c32     3 non-null      int32 
    2   c64     3 non-null      int64 
   dtypes: int32(1), int64(1), object(1)
   memory usage: 188.0+ bytes
   

   Then to plot:

   # int32 => palette
   g.bind(point_color='c32').plot()

   

   # int64 => rgb int
   g.bind(point_color='c64').plot()

   =>

   I opened #243 to help here and will mark this as closed

   If can help further, or this isn't what's going on, would be happy to help!
