Hi, I got two visualizations with the same math aggregation

 ![image](https://us1.discourse-cdn.com/elastic/original/3X/8/b/8bb0d0e894cbed08ea44e5f5f074a62e7ccf1f81.png)

one is an histogram and the other a metric visualization.

 ![image](https://us1.discourse-cdn.com/elastic/original/3X/c/9/c9270c0a5a3a933a31d7fe59670226f0e68b5192.png)

but the value showed in the metric viz, doesnt match the max on the histogram.

why this happen?

So, in the picture below, the blue line represents the sum of the four metrics

```auto
params.tc + params.tm + params.cc + params.cm

```

So I think that I have to separate every bucket and then find the bucket with higher value, something like this:

```auto
max(bucket-with-higher-value)

```

but I dont know what operation I have to do to acomplish that, please help.
