Notes

1. There are three parallel plot variations:



• The basic parallel plot (Plot > 2D: Parallel Plot: Parallel Plot), plots variables on continuous (numeric) scales and uses a color scale for the graph legend.
• The parallel index plot (Plot > 2D: Parallel Plot: Parallel Index) also plots variables on continuous scales but uses a grouping column (a column of Categorical Data) to create the legend and assign plot color.
• The parallel sets plot (Plot > 2D: Parallel Plot: Parallel Sets) plots categorical variables on each axis.
2. When you drag and drop a column of values to a parallel plot, the new column will be added to the last.
