Hi,
I am using the below Timelion expression to plot a Timelion Chart in Kibana for metricbeat data:
.es(index=metricbeat-\*, timefield='@timestamp', metric='avg:system.memory.used.bytes').divide(1073741824).label('Memory Used(in GB) ').color(green).yaxis(1,min=0, **max=8** ,null,'Memory(in GB)')
And it plots a chart of Used-Memory against the y-axis ranged from 0 to 8.
But, I want this max y-axis value to be taken dynamically from the field: **system.memory.total**
Please suggest.

@anisen this isn't possible with Timelion currently, you can open up an enhancement request [here](https://github.com/elastic/kibana/issues/new) so we can gather feedback and gauge interest from the community.
