This free online software (calculator) computes the Star Plot for a multivariate dataset. Every column represents a property of items (rows) that are investigated. The Star Plot creates a chart where every item is represented by an icon (= star) where the shape is determined by the properties (columns) of the item (row). Similar items will be drawn with similar icons. For a moderately sized dataset this allows the user to quickly identify similarity among all items.
Special case: if the columns of the multivariate dataset are time series then the items (icons) represent sequential periods.
Enter (or paste) a matrix (table) containing all data (time) series. Every column represents a different variable and must be delimited by a space or Tab. Every row represents a period in time (or category) and must be delimited by hard returns. The easiest way to enter data is to copy and paste a block of spreadsheet cells. Please, do not use commas or spaces to seperate groups of digits!
