Creating a Cumulative Distribution Plot

The cumulative distribution plot feature is very similar to a histogram, however it represents the cumulative frequencies of the preceding bins. It is used to visualize the proportion of observations (vertical axis) that fall below any given value (horizontal axis). The cumulative distribution plot can also be exported as an image file and saved to the local drive.

Note that it is important to manually save any time dependent information of the cumulative distribution plot when exporting the image file.

Summary Statistics

The cumulative distribution plot displays summary statistics when the visualization is created:

  1. Count is the total number of observations in the dataset of a variable
  2. The mean describes the variable average
  3. Standard deviation (σ) describes how dispersed the variable values are relative to the mean

Process Steps

  1. Select "Visualizations" in the main menu
  2. Select the "Cumulative Distribution Plot" item
  3. A "Create a Cumulative Distribution Plot" window will appear
  4. In the "Dataset" field, select the desired dataset from the Data panel you wish to visualize
  5. In the "Variable" field, select the variable you wish to display in the cumulative distribution plot
  6. In the "Workspace" field, select the desired workspace tab to display the visualization
  7. Choose to display the visualization either in a new pane or to replace an existing visualization by selecting the corresponding pane
  8. Select "OK" to display the visualization
