[dcc.Input(type = 'number', id = 'input %i'%i) for i in range(20)] I want to have one button html.Button('populate parameters', id = 'button populate') that is supposed to populate best pre-fitted value for all the inputs. Code should look like below, except it doesn't work. for i in range(20): @app.callback( dash.dependencies.Output('input %i'%i, 'value'), [dash.dependencies.Input('button populate', 'n

问题 I'm trying to duplicate this d3 map example within React so that I can use it as a component in Plotly Dash. However, there is an issue (I think with D3-tile) that's resulting in undefined strings in the opnestreemap urls. This prevents the code from grabbing the actual images for the tiles, and results in the following image: The errors produced as you zoom in look like this: Here is the full MyMap.react.js code. It seems like the error is coming from the tiles variable not being filled with
