How to Create a Scatterplot from 2 Tables

  • Updated
Follow
The QScript Plot/Chart - Scatterplot from 2 Tables creates a scatter plot showing the data from two separate tables, where:
  • Each of the tables contains a single column of numbers.
  • The row labels of the tables match exactly in terms of text and case.

These tables need to be created prior to trying to create the scatterplot.

Example

The example below shows a performance-importance plot (sometimes called a quad-map), where the performance is SUMMARY of a Pick Any question, and the importance has been measured using Regression - Driver (Importance) Analysis - Shapley.

Technical details

  • The script requests the user to select two tables. Each table must have a single column, consisting of numbers, and have common row labels. You are notified about row labels that only appear in one of the two tables. A scatterplot is created using the numbers extracted from the common rows.
  • The scatterplot will be created from static data copied from the selected tables. Any subsequent changes to those tables (i.e. data updates, recoding, changing filters and weights) will not be reflected in the scatterplot. The script has to be rerun in order to obtain an updated chart.
  • This QScript requires Q 4.9 or later.
