### 3.1 Primitive plotting functions ¶

Yorick features nine primitive plotting commands: plg plots polylines or polymarkers, pldj plots disjoint line segments, plm, plc, and plf plot mesh lines, contours, and filled (colored) meshes, respectively, for quadrilateral meshes, pli plots images, plfp plots filled polygons, plv plots vector darts, and plt plots text strings. You can write additional plotting functions by combining these primitives.
