How to Build a Histogram
A histogram can be built to visualize numerical fields. You can recognize numerical fields by the
label in the field list. The same fields can also be visualized using a Box Plot.
Supported Field Types
Numerical (Integer)
Numerical (Float)
Date
Datetime
Using a Histogram in the Cohort Browser
Below is an example of a histogram visualizing the data field Age:
Histogram: Age
Bins are auto-calculated based on the distribution of the dataset and the axis are always distributed linearly.
Histograms in Cohort Compare
In compare mode, histograms share an axis and overlay one another:
Notes on Data Preparation
- Integer
- Integer Sparse
- Float
- Float Sparse
- Date
- Date Sparse
- Datetime
- Datetime Sparse
While sparse serial types are supported as fields, the non-numeric values are not included as part of this chart type. Special values in the numerical dimension however will be counted and shown separately as a list view.
