Domo Phoenix Aggregations

Hello, I'm new to Phoenix and reading the documentation I'm not able to find how can I aggreate a value.
Let's say for example, I have an input form that generates an API Dataset which I can create charts with.
An example of a simple bar chart looks like this:
In this example, I'm using postBody to make a COUNT aggregation to graph the data.
How is that possible in the Phoenix environment?
This is my code so far:
var columns = [
{
type: DomoPhoenix.DATA_TYPE.STRING,
name: 'userName',
mapping: DomoPhoenix.MAPPING.ITEM
},
{
type: DomoPhoenix.DATA_TYPE.DOUBLE,
name: 'user',
mapping: DomoPhoenix.MAPPING.VALUE
},
{
type: DomoPhoenix.DATA_TYPE.LONG,
name: 'userName',
mapping: DomoPhoenix.MAPPING.SERIES
}
];
And this is my output:
Now what's being displayed with Phoenix is the sum of userId, but I want a way to display the count of a column.
I'd also like to know if there are ways to do other aggregations like sum or average, but most importantly, the COUNT of a STRING field
Thanks in advance.

FYI (For anyone looking at this kind of issue)
I got an answer:
The aggregate is specified when you query the data from the Data API:
https://developer.domo.com/docs/dev-studio-references/data-api
You can still specify the grouping in the Phoenix code, but the aggregations are done by the Data API.
