Summary Statistics presents interval of measured concentrations for one compound in a given matrix and site in individual year. The user selects combination of matrix, compound, parameter, and unit to view relevant concentrations. The output is a horizontal box-whisker chart showing a central point for concentration (median, mean, geometric mean) and its variability (minium and maximum, standard deviations, percentiles) for each sampling site in a given year on selected set of sites and time interval.
Hovering a mouse over a box-whisker line shows additional information related to displayed concentration.
