Dash has made multiple changes after upgrading to version 2.x. We can't modify this video. So for an updated version, please visit our website for the article www.justintodata.com/python-interactive-dashboard-with-plotly-dash-tutorial/.

I am building a desktop app in Python and mySQL which requires some reporting - Dash and Plotly seem to be good choice. Is it possible to add Dash+Plotly as reporting functionality from desktop app (click on button in the app, and web browser opens with reporting tool build in Dash/Plotly) and compile such app into an exe? What I mean is - will the Dash/Plotly functionalities work if I compile such app to exe?
Hi Mladen, we've never had to do it ourselves. But sounds like this article is solving the problem, python.plainenglish.io/how-to-convert-your-dash-app-into-an-executable-gui-b1d4271a8fa7

Hi Francisco, I've never done it myself. But I'm guessing you need to automate updating the csv file in Python and get Dash to read it. Dash can use interval component to read periodically
Hi, Your lectures are really useful to create dashboards using plotly dash in efficient way. Just have one questions ? How we can export these dashboards either in PDF or PPT using dash?
@@shashikantrrathod3617 I haven't had to do anything similar. Perhaps try out something mentioned in this thread stackoverflow.com/questions/52820266/how-do-i-display-a-website-written-in-dash-as-a-static-pdf-python
Hi Ram, you'll need to connect from Python to your database, and grab the data as pandas DataFrame. Then you can use Dash to create a dashboard based on it
Hi, liked this tutorial. I have run into an error while executing the code. Would you be able to help me please? I am new to plotly/dash and relatively new to Python itself. Thanks. The error is: Traceback (most recent call last): File "dash_example.py", line 26, in @app.callback( File "C:\RAOUL\Python\PycharmProjects\PLOTLY DASHBOARDS WITH DASH\venv\lib\site-packages\dash\dash.py", line 1000, in callback callback_id = self._insert_callback(output, inputs, state, prevent_initial_call) AttributeError: 'Output' object has no attribute '_insert_callback'
Hi Raoul, We've never had that error message before so it's hard to say without seeing your code and your environment. But it looks like something to do with your Dash installation. Maybe try to reinstall it again?
Great video. Please advise on how to cluster data and use mutiple drop drowns. For example grouping the cities by state and then accessing the cities. This would help for a company with a large number of products but need to access data by category first before individual products.
Thanks a lot for this very we'll explained tutorial. I should only suggest that the "import" would be a lot simpler if written as "from dash import Dash, dcc, html, Input, Output" (and of course the corresponding modified "app = Dash()" line). But my code being identical to yours I am not getting the dropdownbox displayed and in the browser get the following error: Invalid argument `options` passed into Dropdown with ID "geo-dropdown". Value provided: [ { "label": "Albany", "value:": "Albany" }, { "label": "Atlanta", "value:": "Atlanta" }, .... { "label": "West Tex/New Mexico", "value:": "West Tex/New Mexico" } ] not understanding what's wrong. Any ideas?
@@RobertAlexanderRM Hi Robert, Dash has updated to a newer version in recent months. So now you can use a simpler import statement and provide a list of strings as the options of Dropdown. But the list of dictionaries should still work.
Hi. Thanks for the video, it's extremely informative and helpful. Can you help me with a persistent issue that I am currently facing? Whenever I am trying to import dash_core_components or dash_html_components or dash_bootstrap_components in jupyter , it's throwing an import error, stating cannot import _explicitize_args , has anyone faced this issue here? Please help. Can elaborate more if someone wants. Thanks in advance! P.s I am using dash 1.20.0 , which I believe is the latest version

Is the Udemy course updated to the new version? or its just fundamentals and can be apply to any of the versions?
Hi@@fayalessa7315 Yes, the Udemy course has been updated to the new version.
just went to the tutorial link and the code worked wonderfully. Thank you!
Very well-made video. The pacing and the quality of the presentation of all the content is 100% useful, every second. Thanks!
Very excellent explaination Justin. Thank you very much for the efforts you put to make us understand about the dash layout and callback.
Such a well composed video tutorial, thank you so much Lianne
Excellent video! Got my first dashboard up and running thanks to you.
This was a great video, Simple and easy to understand.
Awesome!!! TQVM!! All new to me. A great introduction video for me!
Good stuff - could this be made "live" - like in a real time display of data being generated in real time.

How does the dcc.Graph object know which graph to show? The update_graph function doesn't have an id attached to it
Hi Pranav, around 9:20, it mentioned that the function returns line_fig, corresponds to the Output in @app.callback, which has id of dcc.Graph
can i get the github repo for this
But how do you make dash update itself every some interval, as data come in?
Hi, please check out dash.plotly.com/live-updates
my chart to produce show the title. where should i look for the problem?
Sorry, you mean you can't see the title of the plotly chart or you want to remove the title? You can change the title in the callback function.

Hi Shashikant, I don't think Dash offers any functions like that. You probably have to use other packages to do that

FWIW if I replace your "options" line with a simple "options=avocado["geography"].unique()," the code works as it should

yep! those imports are deprecated so you may want to use: from dash import dcc
instead of the two import methods you mentioned
Justin2Data is a better name
i wish i was smarter so i could understand this :(
Can we share this link to someone else to see the graph??
Hi Fahad, I'm guessing you are talking about the final deployed dashboard. You're welcome to share it for your personal use.
