A.4.5.39 StatMark Form

The StatMark form (), available from the XYArray Layer Control, plots a set of markers based on a combination (typically the mean) of input array-valued coordinates. The input X and Y coordinates must be fixed-length arrays of length N; N markers are plotted, each one representing the mean (or median, minimum, maximum, ...) of all the input array elements at the corresponding position.

Note that because the X and Y arrays must be of a fixed size for all rows, and because combination is performed in both X and Y directions, this is typically only suitable for plotting combined spectra if they all share a common horizontal axis, e.g. are all sampled into the same wavelength bins. To visually combine spectra with non-uniform sampling, the ArrayQuantile form may be more useful.

The configuration options are:

X Combine
Y Combine
Defines how corresponding array elements on the X/Y axis are combined together to produce the plotted value. The following options are currently available:
