Hi,

My indices have this records:

```
Name Type IO
bay01 diskA 0
bay01 diskA 20
bay01 diskB 0
bay01 diskB 40
bay03 diskC 0
bay03 diskC 10
bay03 diskD 30
bay03 diskD 60
```

A. I need to graph an average on the IO value group by Type,Name:

It's show:

```
Name Type Average IO
bay01 diskA 10
bay01 diskB 20
bay02 diskC 5
bay02 diskD 45
```

I don't have problem to graph this value;

B. Then I need a second graph sum of IO group by Name

But, this sum must use the average of the precedent graph.

I need to have this value:

```
Name Sum IO based on Average Io
bay01 30
bay02 50
```

So in conclusion in this graph I need the sum of IO based on item average.

I don't find in Kibana how I can do that.

The uniq possibility that i find is to do sum. But it show this result and not that I want.

```
Name Sum IO
bay01 100
bay02 80
```

Help please!
