This chapter explains how to create graphs and charts from the data in your NExS spreadsheet. It describes the various graph types and formatting options. A separate chapter provides a comprehensive graphing tutorial designed to step you through the graph making process with simple examples for all types of graphs.
NExS supports Line, Bar, Stacked Line, Stacked Bar, Histogram, Pie, Surface (3-D), Contour, Polar, Hi Lo, Box, and Westinghouse graphs. Variations of Line graphs include X-Y, scatter, and point plots. NExS also provides 3-D rotation of surface plots. NExS can display multiple graphs at the same time, either in separate windows or as cells in the sheet itself.
NExS offers considerable flexibility in defining how graphs and charts look. For instance, you can define how each axis should be scaled, labeled, and tick-marked. You can define whether or not legends, titles, and labels are printed, and, if so, in what font and color. You can choose your own line and marker styles, even shading variants for surface charts.
NExS stores the current graph definition with the spreadsheet, so you can change the data and redraw the graph, or change the graph definition to view different sets of data.
You can view graphs on screen while you continue to work on the spreadsheet, or save graphs as Encapsulated PostScript files to be printed later on a PostScript printer or included in other documents.
