Custom XY Builder: turn a published diagram into a reusable template

How the builder works

• Choose a Cartesian XY or a ternary diagram.
• Load the published figure as a PNG or JPG guide image; it is used for tracing and is not treated as data.
• Calibrate the X and Y axes, or the three sides of the ternary, by marking known values.
• Give each axis a label, a linear or logarithmic scale and a variable or formula such as SiO2, Na2O + K2O, Nb/Yb, (La/Sm)c or (Nb/Yb)m.
• Draw field boundaries and annotations with lines, arrows, polylines, Bézier curves, polygons and text.
• Save the definition as a .kaligeos_template file and reuse it in any project.

Templates included with Kaligeos

The same engine powers the official templates that ship with Kaligeos, including Pearce & Norry (1979), Pearce & Cann (1973) and Gorton & Schandl (2000), each with its original citation.

Plotting and export

• Samples are plotted with the same expression resolver used by Generic XY, so ratios and normalized ratios behave identically.
• Group samples with reusable legend schemes, keep several diagrams linked to the same selection and save views inside a .kaligeos project.
• Export the figure as SVG or PDF for papers, theses and posters. Kaligeos Community includes 50 vector exports per account.
• Kaligeos Community accounts can keep 2 Custom Builder definitions registered at the same time; saving a definition needs an internet connection.

Frequently asked questions

Is the reference image included when I export?

The guide image is a tracing aid. Your exported figure is drawn from the calibrated axes, fields and labels you defined.
