. Such that the colors are maintained based on index even if data is changed. It shows only 15 different colors. After that, the color will be repeated from above colors.
For example, If you are displaying the countries based on the increasing order of the case count, then the index-based color mapping will be useful to set the colors based on the rank. Say red color to the top, then the red color will be maintained for the country having the largest case count.
Note: We prefer to use Index based color customization only for minimum data(upto 15 series).
