Hatching (French: hachure) is an artistic technique used to create tonal or shading effects by drawing (or painting or scribing) closely spaced parallel lines. When lines are placed at an angle to one another, it is called cross-hatching .
Python and Matplotlib are cross-platform, and are therefore available for Windows, OS X, and the Unix-like operating systems like Linux and FreeBSD. Matplotlib can create plots in a variety of output formats, such as PNG and SVG. Matplotlib mainly does 2-D plots (such as line, contour, bar, scatter, etc.), but 3-D functionality is also available.
Skiagraphia is often described as a hatching technique used to create the illusion of forms through shading. [1] The shading is created by the use of curved lines, either by the use of hatching or cross-hatching. Within this same approach, painters can use different colors to add shade to an area.

Michael Wolgemut improved German woodcut from about 1475, and Erhard Reuwich, a Dutchman, was the first to use cross-hatching. At the end of the century Albrecht Dürer brought the Western woodcut to a stage that has never been surpassed, increasing the status of the single-leaf woodcut. [22]
Accordingly, the inker has to translate pencil shading into patterns of ink, for example by using closely spaced parallel lines, feathering, or cross-hatching. The result is that the final look of a penciller's art can vary enormously depending on the inker.
