Available Data – Parameters

Available Data – Parameters shows frequency of individual chemical parameters in a selected data set. Each point (circle) represents a unique combination of parameter (x axis) and sampling site-matrix (y axis).

The size and colour of the point correspond to the quantity of years and occurrence of parameter in a matrix on that sampling site. The more data are available on a site for a parameter, the larger and darker the symbol appears. Hover the mouse over a point to see its summary table.

Please note that both the colour and size of the circle depend on the current data selection (i.e. the same colour can correspond to a different number of samples upon selection of another set of sites or parameters).
