The ability to create Piper Plots was added with the release of Grapher 13. If you are running an earlier version of Grapher, see the article Create Piper Plots In Earlier Versions Of Grapher for instructions.
To create your Piper plots, please use one of the methods below:

The file piper.dat in the samples directory can be used as a worksheet template for your own water chemistry data.
