Thanks for doing such a wonderful work. i was further trying to extend your work my applying a radioButton on top of Add- graph ( Monthly , Daily) sales data . i defined a call back to pass this selected variable M or D to your display_graphs callback , but the value does not seem to go thru. app.layout=dbc.Container(children=[ dbc.Row(children=[ dbc.Col(html.A(html.Span('x', className='myspanclass'),href='/MainMenu'),), dbc.Col(html.H6("Sales Analytics",className='text-center text-primary '),width=10), dbc.Col(html.A(html.Sup(today,className='myspanclass text-primary' ),),), ],), dbc.Row(children=[ dbc.Col(html.Div(children=[ html.Form( [dbc.RadioItems( options=[ {"label": "Day", "value": 'D'}, {"label": "Month", "value": 'M'}, ], value='D', id="radioitems-input", style={'display': 'flex'}, name='myradio', ),], ), html.Button('Add Chart', id='add-chart', n_clicks=0,title='',), ],),), ],), dbc.Row( dbc.Col(html.Div(id='container', children=[])), ), ],className="myclass",fluid=True) @app.callback( Output('radioitems-input', 'name'), [ Input('radioitems-input', 'value'), ], ) def set_options(chosen_month_daily): # print(chosen_month_daily) return chosen_month_daily @app.callback( Output('container', 'children'), [ Input('add-chart', 'n_clicks'), # Input('add-chart', 'title'), # Input('hold-value', 'value'), ], [State('container', 'children')], ) def display_graphs(n_clicks,div_children,): get_month_date_value=request.args.get('myradio') print(get_month_date_value) # print(myvalue) i tried all combinations , but it does not work , if required i can send you the full code basically i need a need a user input (Monthly or Daily) to be passed to the dataframe for filtering data accordingly. thanks and regards

@@naveenshetty2891 Sure Naveen. I have a lot of pending questions to answer, but I'll try to get to yours soon. My email: info@charmingdata.org

sorry to be off topic but does any of you know a way to log back into an Instagram account? I stupidly lost the password. I would appreciate any help you can give me.

@Andrew Alvaro Instablaster =)

@Nathan Quinn I really appreciate your reply. I got to the site thru google and Im waiting for the hacking stuff now. Takes quite some time so I will get back to you later when my account password hopefully is recovered.

Thank you Jaroslav

Thank you Stefan

Thank you for watching Aditya

Thank you Edvard.

You're welcome @Spencer. Let me know if you have any questions in the future.

Hi Jessica, I'm glad the tutorials are helpful for you. I wanted to share that I'm trying to reach my goal of getting a microphone to improve the quality of my tutorials. If you'd like to support, I would be grateful: www.patreon.com/charmingdata Would love to see some code on how you use dynamic callbacks. No te inhibas en mandármelo :) Have a great week,

Lovely. I hope you build beautiful dashboards 🙅

You're welcome. Good luck with your dashboards. Let me know if you have any questions

​@@CharmingData Thank you 😃 I already made a dashboard now for my thesis review. I did stumble upon an issue, how to pass data to the callback on click of a button. In case of a dropdown I could use value. But for a button only n_clicks is allowed. So I decided to pass the data through the id of the button and extract it from the context.triggered as shown in the documentation. 🤔😐

@@abhilashchandran3126 can you please rephrase your question. I'm not sure I understand.

@@CharmingData Sure, I will try 😅. In my case I have about 5 gcc graphs and 5 buttons registered respectively as output and input in a common app callback using the MATCH pattern as you described. For html button the only value we get is `n_clicks` when registered as input. So in the common call back I have no other information other than clicks to identify which button is clicked to perform dynamic time consuming operation based on the button pressed. I will put up a gist.. Thats easier I guess 😁.

@@abhilashchandran3126 why can't you add the dropdown as s callback input and pull information from there?

Thanks @Saïd.

Dear Sir, could u pls help to answer the abovr question ?

Hi @Gonzalo. It depends. How do you want to refer the dropdown value in the second callback. What exactly are you trying to do?

Hi @Mariia what dash version are you using? Are you using the exact code that I provide on GitHub?

Hi @Purvish, I don't think so, not unless you save the generated component as data inside a database, and then, based on a username or password you can reload those components into the original layout.

@@CharmingData Thank you for your reply.

hi PB, you would need to add the delete button similar to what they have here. dash.plotly.com/pattern-matching-callbacks#todo-app

That's a good question, Mike. It's been asked by a few other people as well. You are right that you can just index the dataframe instead of ALLSMALLER. The creators of Dash dynamic callbacks said that they created ALLSMALLER because they think it would be used a lot. I guess if it doesn't get much usage, it might be taken away in future versions.

Thanks for watching Momodou. I'll add it to my todo list

Hi Saad, I answered you via email

hi @Winterbass, Yes. You can probably append the data by using the extendData property of the dcc.Graph(). dash.plotly.com/dash-core-components/graph#graph-properties

Hi Yan, did you watch my most recent video on multipage because I made a similar video a long time ago? If you watched it, I can share how I would share data between pages there. I would put the dcc.Store() in the main app.py file, and then I would use callbacks in the other pages to pull from the dcc.Store through the Input argument.

Hi Enas!! Did you find a solution? Tahnk you

Hi Rahul, please email me at info@charmingdata.org I'll give you the code for that

@@CharmingData Can I please have the code too? Thanks.

for sure Gustavo

HI @Alec, that's an interesting topic. I would love to talk to you more about this. Can you please write me at info@charmingdata.org so we can connect?

Hi Mike. I'm a bit busy with a nice list of future tutorials, but I appreciate your suggestion. If you'd like an opportunity to discuss future tutorials on a more personal platform, feel free to check this out here: www.patreon.com/charmingdata

That is really weird. I've never experienced that, Nicholas. Maybe something is off with that output inside the callback... If you don't manage to solve it, I recommend trying to ask for help on Plotly Dash forum. There are many experienced people there that are helpful.

Thank you very much for your reply and advice! I will surely drop by the forums to search for a solution! When I manage to solve this, if its useful, I will drop another comment here with what I’ve found! Thanks again, and keep up the great content! Cheers!

Nicholas, did you solve it?

I'm not sure why not. Did hover not work for the other graphics?

@@CharmingData I haven't tried it yet, do you know how to do it?

@@ignaciobarrazuazo1867 I'm not sure I understand your question. Are you asking if you can hover over a graph for what purpose? Are you trying to see a hover tooltip?

Hi. We'll... The figure prop of the dcc graph component accepts data like this: figure is a dict with keys: data (list of dicts; optional) frames (list of dicts; optional) layout (dict; optional) That's why it can read either a graph objects figure or a Plotly express figure

Hi wafaa. That's the way Dash works. It's meant to be used by many people at the same time. So if one user changes something, the app stays the same for everyone else. If you want to build an app that you can permanently change, you need to save the new information in a database and make the app refresh from the database data. I show how to do that in my video on dash with live mongodb

@@CharmingData Makes a lot of sense!! Thanks so much, Adam.

Hey Adam :) Another question. Can we use the chained callbacks with combination with the dynamic callbacks here?

Hi Hamza, Thanks for watching the tutorial. I'm not sure I understand your question.

@@CharmingData I run the code, the graph shows up well but the line plot radio button gives an error. AttributeError: 'list' object has no attribute 'sum'

hi Pietro, I don't think it's possible.

yes, that should be possible. But try not to update the global variable

Hi @Shanmukha, try to see how I write the code for this multipage app. github.com/Coding-with-Adam/Dash-by-Plotly/tree/master/Deploy_App_to_Web/Multipage_App If this doesn't help, you can also use dcc.Store() to store data from certain callbacks and import/use them in another python file.

I will. Thank you for the suggestion

Import States from dash.dependencies as -- from dash.dependencies import States

I can try Karen. Write me at info@charmingdata.org

Hello. Yes it is.

What's the error message that it is giving you?

@@CharmingData I think I am having a similar problem. My app with pattern matching callbacks works fine as a standalone app (app = dash.Dash), but when I use app= DjangoDash(...) the pattern matching callbacks don't work (TypeError: list indices must be integers or slices, not str). Any ideas?

@@marcohatt4803 That weird, Marco. I'm not sure why DjangoDash is giving you problems. Did you try to print the object that is giving you this error? try to print type(xxx) Maybe that can give you a clew

@@CharmingData The problem is with the callback. If I do this I get the error @app.callback(Output("graph", "figure"), [Input({'type': 'filter-dropdown', 'dimension': ALL}, 'value'), Input({'type': 'filter-dropdown', 'dimension': ALL}, 'id')]) def make_figure(values, names): ... but if I replace ALL with one of the individual options I don't get the error. And as I said before, there is no problem with app = dash.Dash, just with DjangoDash

@@CharmingData I have posted more details on the problem here community.plotly.com/t/typeerror-unhashable-type-dict-in-dash-app-with-pattern-matching-callbacks/44243 I haven't had any replies yet

Thanks Amir. Very much to the point :)

Check the Dash version you have installed. The dynamic callbacks is a pretty recent addition. I think you need dash 1.13 or above.
