1 year ago While plotly works in Carnets (at least in the TestFlight version), I don't think that dash can work, at least not without modifications: it means running a different command (the app server) on top of the Jupyter server and client, and it probably does this by forking, which doesn't exist on iOS.
I'll have a look, but I don't expect a miracle.
I tried running this relatively simple Dash/Plotly example script: `from dash import Dash, dcc, html, Input, Output import plotly.graph_objects as go
app = Dash(name)
app.layout = html.Div([ html.H4('Interactive color selection with simple Dash example'), html.P("Select color:"), dcc.Dropdown( id="dropdown", options=['Gold', 'MediumTurquoise', 'LightGreen'], value='Gold', clearable=False, ), dcc.Graph(id="graph"), ])
@app.callback( Output("graph", "figure"), Input("dropdown", "value")) def display_color(color): fig = go.Figure( data=go.Bar(y=[2, 3, 1], # replace with your own data source marker_color=color)) return fig
app.run_server(debug=True) `
And got this door traceback:
`SystemExit Traceback (most recent call last) Cell In [16], line 30 24 fig = go.Figure( 25 data=go.Bar(y=[2, 3, 1], # replace with your own data source 26 marker_color=color)) 27 return fig ---> 30 app.run_server(debug=True)
