Class GradientCondition

Access gradient (color) conditions in ConditionalFormatRuleApis. Each conditional format rule may contain a single gradient condition. A gradient condition is defined by three points along a number scale (min, mid, and max), each of which has a color, a value, and a InterpolationType. The content of a cell is compared to the values in the number scale and the color applied to the cell is interpolated based on the cell content's proximity to the gradient condition min, mid, and max points.

// Logs all the information inside gradient conditional format rules on a sheet.
// The below snippet assumes all colors have ColorType.RGB.
var sheet = SpreadsheetApp.getActiveSheet();
var rules = sheet.getConditionalFormatRules();
for (int i = 0; i < rules.length; i++) {
  var gradient = rules[i].getGradientCondition();
