Columns

You have the ability to control columns data. The columns section in the payload is defined as an Array.

Columns fields

Name	Type	Required	Description
text	String	true	The name for the column.
items	Array	true	An Array containing the sub columns.

Items array

Name	Type	Required	Description
text	String	true	The name of the sub-column.
base	Float	true	The base value for this column.
data	Array	true	The data values for each row. This should reflect the same order as the Array of rows defined in the chart settings.

Example in JSON

In this example we can see the correct data structure for 2 columns. In the second column we have two items while in the first column only one item.

{
  "columns": [{
    "text": "Total",
    "items": [{
      "text": "Total n=100",
      "base": 100,
      "data": [16, 5, 37, 42, 0]
    }]
  }, {
    "text": "Gender",
    "items": [{
      "text": "Male",
      "base": 100,
      "data": [16, 5, 37, 42, 0]
    }, {
      "text": "Female",
      "base": 100,
      "data": [20, 15, 47, 22, 10]
    }]
  }]
}
