API Reference > geometry-core > RangeSearch > RangeLengthData RangeLengthData Class Accumulated data for x,y,z length statistics in ranges. Usage pattern: create a enw RangeLengthData: myData = new RangeLengthData (); announce ranges to be accumulated: (many times) `myData.accumulateRowableXYZArrayRange (points); access data in public members: myData.range -- the composite range. myData.xLength, myData.yLength, myData.zLength -- mean, minMax, count, and standardDeviation of range lengths in x,y,z directions. Methods Name Description constructor(): RangeLengthData accumulateGrowableXYZArrayRange(points: GrowableXYZArray): void Extend the range and length sums by the range of points in an array. Properties Name Type Description range Range3d Overall range of all data observed by accumulate methods. xSums ySums zSums Defined in core/geometry/src/polyface/RangeLengthData.ts Line 24 Last Updated: 13 June, 2024
