Collection — Histograms

Accessing Histograms

When you access a collection, click on the Histograms tab to view histograms of collection metric data across the scorecards defined for the current collection.

Configuring Histogram Settings

  1. Using the Metric field, select the metric you wish to view from the available list. If the metric that you are looking for does not exist, make sure that it has been defined in one of your scorecards.
  2. (Optional) Set the Scorecard Objectives field to a scorecard defined in the collection to display scorecard objectives behind the histogram. If the selected metric does not exist on the scorecard or if objectives have not been defined for that metric, this field will be ignored, and the histogram will not display any objectives.
  3. (Optional) Set the Group By field to a custom text or choice metric (or Workspace for Organization Collections). The histogram view will update to display a series of histograms where the data is grouped by the selected item.
  4. (Optional) Toggle on the Compact switch located in the toolbar to view the data as compact boxplots instead of histograms.

Not seeing the metric you want to analyze?

Here are some reasons why you may not be seeing a particular metric available in the metric dropdown:

  • The metric is not the right type (numeric vs non-numeric). Only numeric metrics will appear in the Metric dropdown. Non-numeric custom metrics like text and choice fields are available to select in the Group By field.
  • The metric has not been added yet to a collection scorecard. In order for a metric to show up in the Metric or Group By field, it must be defined in at least one scorecard that belongs to the collection.

Downloading Histogram Data

Download data for the selected metric by clicking the download button in the toolbar above the histogram. Select the type of data you wish to download. Available options include Patient Metric Values, Histogram Distribution Data, and Boxplot Distribution Data. Press Download to initiate the download.

Data Drill-down and Patient Highlight

To view a list of patients that comprise a particular histogram bin, click on the bin. A list of patients will appear below the histograms in the section titled "Bin Selected for Drill-Down Analysis." Double-click on a patient row to inspect the patient.

To determine where a patient falls in the population for the selected metric, open the patients right sidebar, and click the patient to select it. The bin containing the selected patient will be highlighted with a solid black outline.
