How to Build a Stacked Row Chart

A stacked row chart can be built when combining two categorical fields. The same combination can also be visualized as a list view.
Dimension 1
Dimension 2
1x Categorical (categories <=20)
1x Categorical (categories <=20)
Each Dimension 1 category is displayed as a row. Each Dimension 2 category is displayed as a set of color-coded segments within the rows.
Categorical multiple and categorical hierarchical fields are not supported in stacked row charts.

Using Stacked Row Charts in the Cohort Browser

Below is a sample stacked row chart: Coffee Type by Gender. From the second row we know there are a total of 42,761 patients in the current cohort selection who drink instant coffee, with 23,278 of them being female.
Stacked Row Chart: Coffee Type x Sex
Stacked row charts allow swapping the two categorical dimensions in their primary/secondary order. Below is an example combining the same fields Coffee Type and Gender, only this time Sex is used as the primary dimension.
Stacked Row Chart: Sex x Coffee Type
Stacked row charts are not supported in Cohort Compare. To use a stacked row chart when comparing cohorts, convert it to a List View.

Note on Data Preparation

The following Ingestion Data Types are supported in stacked row charts:
  • String Categorical
  • String Categorical Sparse
  • Integer Categorical
While sparse serial type fields can be used to create a stacked row charts, non-encoded values are not supported by this chart type and therefore may not show up correctly in the chart.
