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:

chart1.JPG

 

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:

chart2.JPG

 

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.
