How to Build a Row Chart
A row chart can be built visualize categorical fields with a limited number of category items. You can recognize categorical fields by the
label in the field list.
Note that categorical fields with a hierarchical structure cannot be added as row charts. Both cases can be visualized as List Views instead.

Using Row Charts in the Cohort Browser
A row chart shows a row for each category, along with number of records within current cohort selection that fall under that category.
Below is a sample row chart of data field: "Salt added to food", which has 5 categories. In current cohort selection of 100,000 participants, 27,979 participants have value "sometimes", which is 55.31% of the current cohort size.
While preparing data, make sure sure categories are specified as codings,which allows them to be visualized correctly.
Note: While _sparse serial types can be visualized as row charts, non-encoded values are currently not supported by this chart type and thus will not appear as rows in the chart.
