Graphis graphing software is a powerful scientific/engineering data visualization and analysis tool. At the core of its functionality is the ability to create both tabular and analytical curves. Tabular curves can be used to plot data held in tabular form, while analytical curves can be used to plot mathematical expressions.Tabular curves are created in Graphis by entering data manually into a curve’s table, by pasting it from another application such as Excel, or by importing it from data previously imported into a Graphis Spreadsheet. Graphis spreadsheets allow data to be imported from character-delimited text files using an Excel-like data import feature. (Source:
