The StatLine form (), available from the XYArray Layer Control, plots a single line 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; a line with N points is plotted, each point 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.
Example StatLine plot
StatLine form configuration panel
The configuration options are:
the mean of the combined values
the median of the combined values (may be slow)
min: the minimum of all the combined values
max: the maximum of all the combined values
the 1st percentile of the combined values (may be slow)
the first quartile of the combined values (may be slow)
the third quartile of the combined values (may be slow)
the 99th percentile of the combined values (may be slow)
the sample standard deviation of the combined values
sum: the sum of all the combined values
count: the number of non-blank values
