How to Plot Streaming Data from ek.StreamingPrices?

r.patel · March 2020

I've successfully used created a cache using ek.StreamingPrices and have been able to see a pandas DataFrame update with streaming prices. However this is all i am able to do. I am wondering how you can further utilize this data and work with it. I am looking primarily to visualize streaming prices but have no luck. Any help would be appreciated, Thanks!

Hi @r.patel

According to your post, I understand that you already have data in a dataframe.

So you can read this article to visualize the data to many chart types.

Hi @r.patel,

In terms of what the API can do for you, it will maintain an up-to-date cache of the data - which is what you are currently using it for. It also provides the ability to capture realtime updates through lambda expressions. For example, from the Eikon PiPy page:

With this capability in place, you can visualize streaming data within your applications based on changes in the market.

Hi @r.patel. Are you using the `on.update = ` parameter to write to the DataFrame? Do you mind appending some code example to your question for that part?
