Graphis graph plotting software uses the familiar Multiple Document Interface approach to displaying graphs, where each document represents a Graphis project. Graph layout is completely WYSIWYG with each project consisting of a set of pages and each page may contain any number of graphs. Graphis visualization software can be used to construct graphs, each consisting of a set of plots, with each plot containing one or more curves. All plots and curves for a graph are created and modified using the Plot Dialog, as shown in the figure. The Plot Dialog consists of a tree view control on the left, and a set of property pages, accessed via a list in the centre. The tree view lists all plots and curves that have been added to the graph, and the property pages on the right hold the properties associated with the currently selected plot or curve. Any property for any plot or curve in a graph can be easily accessed and modified by simply selecting the plot or curve in the tree view and selecting the list item corresponding to the page holding the property you want to change. Full support is provided for printing and print preview, and Graphis graphs can be saved as bitmap images or used in OLE clients as embedded objects. Various data analysis plot types are also included  as standard features. .
