The xpicture package
Fuster Capilla, Robert Ricard · 2013
The xpicture package extends the graphic abilities of the standard LATEX environment picture and the packages pict2e and curve2e, adding the ability to work with arbitrary reference systems, Cartesian or polar coordinates. Furthermore, in addition to drawing lines, vectors, polygons and polylines, this package allows you to draw conic sections and arcs, graphs of functions and parametrically dened curves. These curves are composed by using quadratic B ezier approximations automatically determined using the calculator and calculus packages.
