Why Is My Data Missing from the Piper Plots?

The data used for the Piper Plog is identified by the ChemCodes below, which need to be reported in standard units (eg mg/L). ESdat then converts the result into milliEquivalents. Where multiple ChemCodes are listed they will be used in the order of precedence shown below.   

If data is not being outputted, either there is no data for the ChemCode or a unit conversion could not be performed.
