From the DISLIN website:

The library contains the following features: Plotting of 2-D and 3-D systems with linearly or logarithmically scaled

axes. Plotting of curves. Several curves can appear in one axis system and can

be differentiated by color, line style and pattern. Multiple axis system can be displayed on a page.

Elementary plot routines for lines, vectors and outlined or filled regions such as rectangles, circles, arcs, ellipses and polygons.

9 software fonts where each font provides 6 alphabets. PostScript fonts and TrueType fonts for Windows displays can be used. The different alphabets contain Roman, Greek, and mathematical characters.

Contouring Business graphics. Elementary image routines
