*Parallel coordinates* are a way to plot multivariate data. They are primarily used to visualize the relationships between many **numeric** variables. The chart gives each variable its own axis and positions it in parallel to the other axes, with the data points plotted as a series of lines along each axis.

## Requirements

**Numerical** data must be used for the plots. It is optional to select a **nominal** or **ordinal** variable to define the colors of the plot.

The variable order of the parallel coordinates chart will determine how the axes are arranged.

## Method

1. Go to **Anything > Visualization > Exotic > Parallel Coordinates**

2.** In the object inspector go to the Data Source tab.**

3. Under **Data Source** - insert numeric variables you'd like to use. Note - the order in which these are entered will be the order from left to right of the plot

4. OPTIONAL: Choose color variable. This variable must match the names in the numeric variables and be **nominal** or **ordinal**

5. OPTIONAL: Check **Variable Names** - to instead insert variable names into the plot

6. OPTIONAL: **Tidy Labels** - extract common prefixes to simplify names (default)

7. OPTIONAL: **Reverse Axes** - show smallest values at top of chart (default)

8. OPTIONAL: **Enable interactions** - can select lines to filter the plot

Example - Heavy Pepsi drinkers at home:

9. OPTIONAL: **Render lines progressively** - shows an animation of the lines in the plot
