Hello,  
I would need to use math function splines in timelion. How can I do? Is it supported? There is an alternative way to smooth the angles of line chart in timelion?  
thank you very much for help me!!

Hey there,

We unfortunately do not support the spline function, but you can try and use the [moving average](https://github.com/elastic/timelion/blob/master/FUNCTIONS.md#movingaverage) function for smoothing. Also, see [this blog post](https://www.elastic.co/blog/sparse-timeseries-and-timelion) for more things to try as well.

If this doesn't help, I can dig more if you share the timelion query you're using.

Thanks,  
Chris
