Basic Spider Chart Knowledge
Spider chart, also called radar chart, star chart, web chart, etc., provides a view of data comparing the client company's performance to that of its competitors' various areas, illustrating strengths and weaknesses. To help you to know better about spider chart, we will introduce some basic spider chart via a simple spider chart example.
Brief History of Spider Chart
Typically, spider charts are generated in a multi-plot format with many stars on each page and each star representing one observation. The star plot was first used by Georg von Mayr in 1877. Spider charts differ from glyph plots in that all variables are used to construct the plotted star figure. There is no separation into foreground and background variables. Instead, the star-shaped figures are usually arranged in a rectangular array on the page.
