:: Star Plot - Free Statistics Software (Calculator) ::

All rights reserved. The non-commercial (academic) use of this software is free of charge. The only thing that is asked in return is to cite this software when results are used in publications.

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!
