KMeans2D - chart function

KMeans2D() evaluates the rows of the chart by applying k-means clustering, and for each chart row displays the cluster id of the cluster this data point has been assigned to. The columns that are used by the clustering algorithm are determined by the parameters coordinate_1, and coordinate_2, respectively. These are both aggregations. The number of clusters that are created is determined by the num_clusters parameter.

KMeans2D returns one value per data point. The returned value is a dual and is the integer value corresponding to the cluster each data point has been assigned to.


KMeans2D(num_clusters, coordinate_1, coordinate_2)

Return data type: dual


Argument Description
num_clusters Integer that specifies the number of clusters.
coordinate_1 The aggregation that calculates the first coordinate, usually the x-axis of the scatter chart that can be made from the chart. The additional parameter, coordinate_2, calculates the second coordinate.
