ProfileData is a two-dimensional array (Number of Rows - 1, Number of Columns - 1) of double. The number of rows is Profile(idx).NumSamples, where idx is the profile index to set/get the x & y values for. The number of columns is 2, one to store the x-data and one to store the y-data.
Initially, all data values are 0. Two common methods to populate the ProfileData array are:
