Hi everyone, I’m trying to Real Time Visualization with Bokeh, My data is Json format. I found partial applications. But I couldn’t collect them. Do you have any sample or suggestion for me?
Hi,
This question is far too vague for anyone to give any meaningful advice, you will have to describe what it is you want to accomplish in much more detail.
Thanks,
Bryan

You’re right, I’m sorry, the situation is like this, I’m trying to create a graphic like I showed in the picture. But my data source works in real time. New data is constantly being generated. I need to transfer this data to the graph simultaneously.
My data source url=> ‘http://uoweb1.ncl.ac.uk/api/v1/sensors/live.json’ and
my api key =>‘5esj2vxuzkszejyrcxmo4k7o6qckkgr4sa5f1bynb68odfg392yc4tb9w44551wel5nxbrtnsqnlsxh798nte9gmgf’
I’m tried to use
"
source.stream(new_data, 300)
"
and but I have many many error. I am sorry but I have been using python for the last 1 week and I met Bokeh for the first time. I do not know if it can be very simple or very difficult, but if I can find a similar example, maybe I can do it myself. Bokeh, Bokeh Serve, Curdoc, Layout, Figure, ColumnDataSource etc all caused my very big complexity. What I think is,
-
Convert JSON data to ColumnDataSource
-
Assign a ColumnDataSource to the Source
-
Attract new data at specific intervals and add to the source.
But I can not.
Another problem is that I need to keep the data for the last 24 hours and should I store this data somewhere such any database? Or does Bokeh Serve allow this?

Hi Tuba,
It is certainly ambitious to try an app of this complexity after a week of working in Python. If this is your first programming experience in general, I would really recommend a more gentle introduction, rather than jumping directly into the deep end. A lot of the questions you asked are good questions about application architecture in general, and are not specific to Bokeh or any visualization platform.
That said, there are a number of examples of Bokeh applications that are updated as new data arrives.
https://github.com/bokeh/bokeh/tree/master/examples/app/spectrogram
http://matthewrocklin.com/blog/work/2017/06/28/simple-bokeh-server
https://zduey.github.io/snippets/streaming-stock-data-with-bokeh/
After studying these, if you are still unable to get your app to work, follow up with specific questions and include minimal verifiable code demonstrating the problem.
cheers,
Dennis
