plotly / dash-volatility-surface Goto Github PK

Demonstration has no installation instructions. Creating and running this in Spyder throws all kinds of errors !!

I am running this demonstration in Spyder, in its own virtual environment using Python 3.8.5.
I see the requirements.txt file says to use Python 3.6.1 or higher.

The link for instructions jumps to a totally irrelevant Plotly marketing page, not installation instructions.

_ It is very frustrating for new Plotly developers trying to assess the business value of Plotly and Dash._ When demos are not maintained, it says a lot about the Plotly company. Do they actually care about people who are (not yet?) customers. Why can't Plotly maintain their finance demos?

Is there an updated version of this demonstration somewhere that works? Can someone please provide some pointers to get this working? I cannot spend a ton of time debugging these out of date Plotly core packages.

For purposes of this demonstration, it would be best to include some CSV data files that work, rather than trying to maintain it by chasing data providers' deprecated APIs. What other free option data sources are there besides the broken Yahoo API?

Thanks for an interesting example. I hope it gets updated soon.

The data_fetcher module provided by Plotly is broken and throws an error saying a package is missing.

**After installing py_vollib, I get another error.**

The data_fetcher module is broken without a replacement being made available for the Yahoo data API.
Using the get_raw_data() function to test data function reveals the problem.

get_raw_data("AAPL")

ImmediateDeprecationError: 
Yahoo Options has been immediately deprecated due to large breaks in the API without the

connectors are welcome.

After figuring out that the demo needs the py_vollib package, and executing app.py, the following error is thrown .

Hi,

I seem to be experiencing issues with locking the camera / zoom settings into a certain area of the heatmap in your app. For instance, if I zoom into a certain sub-region of the heatmap you have in the lower left corner of the application and then I toggle the "Price threshold" slider, the zoom layout is reset. I also attempted to mimic your code for preserving layout in my own app and experience the same issue. Can you please check and confirm whether you are in fact observing this issue as well?

Thank you and look forward to hearing back!
