The copyright holder grants you permission to redistribute this document freely as a verbatim copy. Furthermore, the copyright holder permits you to develop any derived work from this document provided that the following conditions are met. a) The derived work acknowledges the fact that it is derived from this document, and maintains a prominent reference in the work to the original source. b) The fact that the derived work is not the original OpenMath document is stated prominently in the derived work. Moreover if both this document and the derived work are Content Dictionaries then the derived work must include a different CDName element, chosen so that it cannot be confused with any works adopted by the OpenMath Society. In particular, if there is a Content Dictionary Group whose name is, for example, `math' containing Content Dictionaries named `math1', `math2' etc., then you should not name a derived Content Dictionary `mathN' where N is an integer. However you are free to name it `private_mathN' or some such. This is because the names `mathN' may be used by the OpenMath Society for future extensions. c) The derived work is distributed under terms that allow the compilation of derived works, but keep paragraphs a) and b) intact. The simplest way to do this is to distribute the derived work under the OpenMath license, but this is not a requirement. If you have questions about this license please contact the OpenMath society at http://www.openmath.org. plot1 2013-04-11 0 0 experimental fns1 interval1 A CD describing plots in 2 dimensions. This CD describes plots in a two dimensional Cartesian coordinate system. It can be used to describe function plots, which can then be converted to images by several different plotting programs. configuration This symbol describes a 2-dimensional image. It consists of at most one viewport, and any number of plots (like functionplot). domain This symbol describes the domain of a function to plot. It contains a single argument, which is the domain. This can be used to calculate the function on part of the viewport. functionplot This symbol describes a functionplot. The first argument should be a function. Optional arguments are a range for the function and a label for the function. label This is a label, to be displayed near a function. This can be useful if several functions are drawn in the same picture. It has a single argument, which should be an openmath string. viewport This symbol describes the viewport on the coordinate system. Its first argument is an interval for the values of the x-coordinate, the second argument is an interval for the values of the y-coordinate.
