Hi all

I am creating a TimeLion visualization in Kibana 7.7.0.  
My Timelion is as follows

```auto
.es(index=my_index_1,metric=cardinality:conversation_id,q=*,timefield=ts).label('NEW CONVERSATIONS'),
.es(index=my_index_2,metric=cardinality:conversation_id,q=*,timefield=ts).label('ALL_CONVERSATIONS')

```

Now I need a third graph that diplays a third metric  
Ration of new conversations to All Conversations  
(NEW CONVERSATIONS) / (ALL\_CONVERSATIONS)

How do I do that ?

Thanks

sanjay

I think I may have figured it out

I added a third time series

.es(index=my\_index\_1,metric=cardinality:conversation\_id,q=_,timefield=ts)  
.multiply(10)  
.divide(  
.es(index=my\_index\_2,metric=cardinality:conversation\_id,q=_,timefield=ts)  
).label('PERCENTAGE')
