Gri is a language for scientific graphics applications. By 'language'
|
||
|
|
I mean that it is a command-driven application, as opposed to a
|
||
|
|
click/point application. It is analogous to latex or tex, and shares
|
||
|
|
the property that extensive power is the reward for tolerating a
|
||
|
|
modest learning curve. Gri output is in industry-standard PostScript,
|
||
|
|
suitable for incorporation in documents prepared by various text
|
||
|
|
processors.
|
||
|
|
|
||
|
|
Gri can make x-y graphs, contour-graphs, and image graphs. In
|
||
|
|
addition to high-level capabilities, it has enough low-level
|
||
|
|
capabilities to allow users to achieve a high degree of customization.
|
||
|
|
Precise control is extended to all aspects of drawing, including
|
||
|
|
line-widths, colors, and fonts. Text includes a subset of the tex
|
||
|
|
language, so that it is easy to incorporate Greek letters and
|
||
|
|
mathematical symbols in labels.
