使用法

• Displaying points as different colors based on the values of a numeric attribute is an example of a graduated colormap. This kind of map is most useful for showing data that is ranked (such as 1 to 10 or low to high) or has some kind of numerical progression (such as measurements, counts, rates, or percentages) since colors don't necessarily imply a magnitude.
