Hi everyone! Great tool this is. Quick question: I have deployed Lightning on Heroku. So far so good. When using the streaming graph, I only get viz updating when I visit the permalink and not the public link. I thought this could be because I was using the free dyno but I bought a hobby dyno and the result is the same. Should I give it a try on the last pricing option? Thanks!

@mathisonian
@rt_producer_twitter it should be the same regardless of the dyno type
so maybe a bug - could you make an issue on github

Hey guys, is the map option only available for the US?
I am trying to get some visualization in Canada
Matthew Conlen
@mathisonian
@elebumm yeah, its only implemented with the US and world maps right now

Hi everyone! I'm interested in using Lightning, due this I would like to know if its possible to use it in a Jupiter Notebook with a custom kernel (not the ipython kernel) using the JS client?

hi there - simple question. I'm using lightning locally with a jupyter notebook. When I run the following command

values = random.randn(100)
lgn.histogram(values, 10, zoom = False)

I get the above (and no visualisation):

any ideas?

@isaacasamoah
solved: when initialising lightning locally I didn't include the "Ipython = true" argument.

Having a problem with the histogram - using jupyter notebook on windows 10, python 3.6 getting the following error. other plots like scatternd line are working fine...
Javascript error adding output!
Error: Module name "lightning-histogram" has not been loaded yet for context: _. Use require([]) http://requirejs.org/docs/errors.html#notloaded

Anyone else have this issue? TypeError: parse() got an unexpected keyword argument 'transport_encoding'

@rt_producer_twitter I tried the streaming scatter plot on both heroku links and it didn't work :( "status of 500 (Internal Server Error)"

Is the public server on http://public.lightning-viz.org/ no longer functional? Anyone still using Lightning? I just recently discovered it, and it appears I missed out on all the fun. I would love to use it for a project I'm working on.
Matthew Conlen
@mathisonian
hey @parkerduckworth . yeah, unfortunately we had to shut down teh public server due to funding drying up, and similarly i'm not actively working on the project any more. that being said, you can still stand a server up yourself and use all the open source components
although i may recommend using https://plot.ly/ at this point since its more well supported and they've open sourced all their components at this point (it was all closed when we started lightning)

Hi,
In streaming scatter
is it possible I can have some points to stay instead of disappearing
any parameter that controls this?

@adrienpacifico
Hi @parkerduckworth , many thanks for your work ! Could you inform users, on the main page of http://lightning-viz.org/ that the project is not actively developed anymore ? I spent 40 minutes trying to find out if it could be a good alternative to plot.ly before reading your January 10th message :-) . Best !

Hi I am having trouble launch the Import Visualizations Modal Dialog - I have tried on both Chrome and Safari - also I am not a pro in Visualization technologies or JavaScript, any help for this dummy will be appreciated.
Dang! So there is no support - that sucks! I will checkout Plotly but I am kinda sad, this didn't become a success.
