With polar graphs (stereonets), the orientations of lines and planes at various scales can be plotted to preserve planar and linear features (and their angles). A polar stereonet is good for plotting large quantities of trend and plunge data directly, or reporting data like foliation planes and lineation in rock layers. gINT Graphs can output data using a polar graph (gINT version 7 and later).

To report the relationship of dip angle to direction for planar and linear features in rock cores, a polar graph is used:

Positions, shapes and colors of data markers on the stereonet plot are calculated or assigned by the report, using the rock core data recorded in the project database.

A pre-drawn stereonet plot in a Graph report is available for English and metric units in A-size and A4-size output from the gINT Web site. For custom polar graphs, you can draw your own in the included gIDraw (CAD) drawing application using the polar array feature.
