Yes, Grapher 13 added this functionality, so now you can create Piper Plots quicker than ever.
To create your Piper plots, please use one of the methods below:
- Click Home | New Graph | Ternary | Piper Plot
- Click Home | New Graph | Ternary | Piper Class Scatter Plot
The file piper.dat in the Grapher 13 samples directory can be used as a template worksheet for your own water chemistry data.
A classed Piper plot created from the piper.dat file in the Grapher 13 samples folder.
The Graph will be divided into 13 components :
- The Diamond, Anion and Cation plots, which plot the data points from the spreadsheet.
- 4 Diamond plot axes
- 3 Anion plot axes
- 3 Cation plot axes
For more information on creating and editing piper plots in Grapher 13, see the Piper Plots (Trilinear Diagrams) training video.
For Grapher 12 and earlier:
Grapher 12 and earlier cannot directly create a Piper plot, however it is still possible using the workflow in this article: Can I Create Piper Plots In Earlier Versions Of Grapher?
