Color is the most important Appearance dimension and can be used in all Plot Types. This dimension will change the color of your points, bin, and surfaces to represent the value of that object for the assigned feature.
What every color represents is shown in the Legend panel. This dimension should almost always be used when creating four dimensional and higher visualizations.
Color allows all feature types and is equally useful for both numerical and smaller categorical features. When a categorical with many unique values is used on color, the 15 values that appear in the greatest number of rows will be shown, with all other rows grouped into an “Other” category. For this reason, Color may not be useful for very large categorical features.
Color settings are found by switching to the Settings tab in the Mapping panel and selecting the Color/Shape button:
- Color Bin
- Color palette selections – Select different colors to represent your bins
- Reverse color palette button – Reverse the shown color palettes
- Bin Distribution – Numerical only, changes between creating grouped ranges by frequency (all bins contain similar numbers of points) and range (all bins have similar ranges of values)
- Bins Slider – Numerical only, set the number of bins displayed
- Color Gradient
- Color gradient palette selections – Numerical only, select different ranges of colors. Assigns all points a unique color according to how high or low the value of the selected feature in that point.
- Reverse gradient color palette button – Numerical only, reverses which color represents high and low
- Color Normalization – See Normalization
