Dynamic Graph based on User Input - Data Visualization GUIs with Dash and Python p.3

Welcome to part three of the web-based data visualization with Dash tutorial series. Up to this point, we've learned how to make a simple graph and how to dynamically update HTML elements in real-time without a page refresh. While we were just re-outputting the same text as we input, we can also apply some more logic to the input, and output anything, not just text, such as a graph. That's what we're going to do here.

already deprecated by Google Finance. We need to update the data puller. Here's a quick snippet example using morningstar instead of google or yahoo:

df = web.DataReader("TSLA", 'morningstar', start, end)
df.reset_index(inplace=True)
df.set_index("Date", inplace=True)
df = df.drop("Symbol", axis=1)

best tutorial i've seen thank youu i've been searching for so long

[abelgebreegziabher]

have been using Dash z last couple of weeks and I am really also impressed by its simplicity. The trick is just to know how to learn how you can use plotly for simple graphs(line, scatter, bars, histograms)....now i know how to use it for some kind of streaming data.... Thanks Sentdex

"Bee bop onto our scipt-erino over here!" LOL

[tyrantus]

if someone has errors at the beggining just ust 'yahoo' instead of 'google', and update pandas

[Shelto]

changing google to yahoo worked for me

[SeamusHarper]

Since GFinance AND Moringstar are deprecated as of now: It's dangerous out there, take one of these:

stock = 'GDP'
df = web.DataReader(stock, 'fred', start, end)

and

{'x': df.index, 'y': df.GDP, 'type': 'line', 'name': stock}

Lots of headaches, headaches that can be prevented simply by using an actual IDE : )

Hi.
The error you encountered is in fact related to the fact that you didn't know why a list of Input elements is used, it's in case of multiple Input elements you would want your Output element depend on. It's quite intuitive i think😊

great tutorial man! I would just add a try catch/except in case someone enters an invalid ticker, cheers
