This guide will go into more detail about how Narratives for Qlik analyzes scatter plots and performs regression analysis.
Scatter plots with Two Measures
In this example, a Qlik sheet has a scatterplot with a single dimension (Product Group) and contains two measures (Back Orders and Margin Amount).
Order of the measures matters: The first measure in the sidebar is what will appear on the x-axis. The second measure will be on the y-axis. Therefore, the narrative will analyze the impact the independent variable (Back Orders) has on the dependent variable (Margin Amount).
Scatter plots with Three Measures
In this example, a Qlik sheet has a scatter plot with a single dimension (Product Group) and contains three measures (Back Orders, Horsepower and Margin Amount).
While this scatter plot has three measures, the user will still see a two dimensional plot (i.e., just a visble x-axis and y-axis). However, the size of the third measure values is represented by the size of the bubbles in the plot.
Similar to the two dimensional scatter plot, order of the measures on the right does matter. When scatterplots are created with x,y and z axis, analysis is typically focused on the impact that x and y have on the z-axis.
In our example, the relevant analysis is answering the question, "What was the impact each of Back Orders and Horse Power had on Margin Amount (if any)?"
If a user wants to change those independent and dependent variables, the measures on the right sidebar can be dragged and dropped into a different order to change the regression analysis performed.
