How to add custom functions to kibana timelion?

[saii]

i have read the following article

Implementing a statistical anomaly detector in Elasticsearch - Part 2

The footnotes in the article gives steps to add a custom function to Timelion..it says to add the function in a specified path and then remove the timelion bundle file. After doing this when i restarted kibana, the kibana interface is stuck. is this the only way to add a custom function? or is there any other method to do it? Can we actually add custom functions to the Timelion? kindly help me out..
Thanks in advance..

There's a good chance that the functions there aren't compatible with a newer version of Kibana. The recommended workflow now is to create a plugin, https://github.com/rashidkpc/timelion-random can be used as a reference.

Can share the error in your browsers developer tools?
