What is Grapheme?

Grapheme is a graphical, data analysis and visualization software package designed for all users and industries but specifically for scientists and engineers. With Grapheme's easy-to-use workspace and Wizards there is no need to struggle with complex programming languages or equations to analyse your set of data. Once you import your data into a project, Grapheme helps you organize, analyse and visualise them.

Is Grapheme a spreadsheet?

Grapheme is an alternative to spreadsheets. Instead of defining data in cells that contain single values, Grapheme organises data in columns and tables. A Grapheme project can have multiple tables and you can operate on each table editing single values and defining arbitrary computed columns. Each table can have multiple views (i.e. dynamic filters) which you can dynamically create and edit via user-friendly Wizards also performing statistics and advanced visualisation tasks.

How many data can Grapheme handle?

Limits are given by hardware resources only. Grapheme has been designed to handle charts with several thousands of points and tables with millions of values on normal laptops. Of course, large data take longer to process but Grapheme handles sets of data that are too large for many other commercial solutions on the market.
