Hi,

Hopefully you can help me with this question I have about visualizing timelion calculation result.

Let's say there is a command **A** that runs and takes certain time to run. Later command **B** was introduced that does the same thing but faster. For each command I post into elastic search document with `duration`

and `command`

fields. What I want to accomplish is to display amount of time saved by introducing command **B**, given that **A** and **B** will be used in parallel for some time.

It looks like that in order to calculate this I have to do:

`(AvgA - AvgB) * CountB`

Where

`AvgA`

- is average duration of command **A**

`AvgB`

- is average duration of command **B**

`CountB`

- count of home many times command **B** were ran.

So I came up with this timelion script to calculate it

```
$A = 'command:"A"',
$B = 'command:"B"',
$ACount = .es(index='index', q=$A, metric=count).aggregate(sum),
$BCount = .es(index='index', q=$B, metric=count).aggregate(sum),
.es(index='index', q=$A, metric=sum:duration).aggregate(sum)
.divide($ACount)
.subtract(
.es(index='index', q=$B, metric=sum:duration).aggregate(sum)
.divide($BCount))
.multiply($BCount)
```

As a result of this I'm getting graph with steady horizontal line where Y axis represents result of this calculation. What I would want is to show this in form of a number instead. It looks like timelion has `.bars()`

and `.points()`

which will represent it in form of bars or points. It doesn't seem like there is a way to represent this in form of a number.

The other question I have. Is there a way to do this calculation that I'm doing in `metric`

field, so that I can draw graph where X axis will be time and Y axis will be result of this aggregation for the specified aggregation interval. So that, this way I can build cumulative graph for example.
