During the petrology field trip, we plotted our thin-section results on a QAPF diagram to identify the rock types.

Using a Hubble diagram, the research team plotted galaxy redshifts against their estimated distances to measure the expansion rate of the cosmos.

The researcher used a Jones diagram, a type of Cartesian graph where each axis represents a different variable and opposite directions along an axis represent distinct quantities rather than positive or negative signs of the same quantity, to analyze the device's phase and amplitude responses.

During the lab session, the students plotted their zircon U–Pb measurements on a concordia diagram to estimate its crystallization age.

The geochronologist plotted the zircon analyses on a Wetherill diagram to assess the concordance of the uranium–lead ages.

During the protein modeling workshop, the instructor demonstrated how to interpret a Ramachandran diagram to assess backbone conformations.

The energy audit used a Sankey diagram to clearly show where heat losses occurred throughout the plant.

The experimentalist explained how the penguin diagram contributes to rare B-meson decays.

The engineers updated the state diagram to reflect the new error-handling paths.

The astrophysics class used an HR diagram to compare the luminosities and temperatures of nearby stars.
