The concept behind ternary diagrams in
All ternary diagrams are simply PDF files usually stored under "Applications//Ternary diagrams". This folder contains several folders, each representing a different discipline of the Earth sciences. Plots are saved in these folders, and are automatically loaded in the background of your plots when you choose them.
Creating your own diagrams
To create your own diagram, locate the folder named Personal files and containing a file named Template.pdf. Simply duplicate this file and rename it appropriately (i.e. with an explicit name such as "Streckeisen"). I recommend that you keep your personal diagrams in the Personal files folder since the other folders might be modified by future releases of . By saving these files in the Personal files you thus avoid loosing your work. Then, open your new file with a program capable of reading and writing PDF files such as Adobe Illustrator.
You can edit your file the way you wish, but keep two important things in mind:
1) You should never move or resize the triangle of the template file since it is calibrated for a correct plotting into , and
2) keep in mind that the upper left corner of the plot is reserved for displaying the legend.
Once you have edited your plot, simply save it into the Personal files folder. Next time you open , you will be able to use this new plot. To make sure that you did not modify the geometry of the graph you can plot the grid on top of your diagram and thus check it.
The ternary plot database and sharing your plots
Once your plot is created, please send it to cedric.john@crog.org. Add a short description of the plot, the field to which it applies (such as "mineralogy", "paleontology", etc...) as well as a reference for the original plot.
Your plot will be added to the plot database and your contribution acknowledged in the About t menu. Sharing your plot will avoid other people to redo the same work, and will extend the choices offered by DeltaPlot. You can check for new releases of the plots database at www.crog.org/cedric/dplot. Thank you for sharing your diagrams!
