GWChemPlot is a Python module to make groundwater hydrochemical graphs (Schoeller, Piper, and Stiff); GWChemPlot stands for Groundwater chemical plots.
The functions that build the graphs have been adapted with slight modifications from the WQChartPy package https://github.com/jyangfsu/WQChartPy.
Other functions are added to calculate the charge balance error of the hydrochemical analyses and to classify the ion's dominance.
