Spider plot tool

Plots matrix column data in a spider plot.

Description

Function plots table data in a spider (or radar) plot form. Permits independent or global axis limit controls as well as axis labeling and data set labeling. Also allows for the plot axes to be specified. Any inputs other than the data to be plotted can be left as null ([]) which then uses the default settings. Minimum of three axes (three rows to the data) required (technical limitation to a spider plot). No maximum on number of rows (axes) or columns (data sets) but plots can get busy if rational limits are not used.

Examples are included in the help listing for usage methods.

% create a spider plot for ranking the data
% function [f, ca, o] = spider(data,tle,rng,lbl,leg,f)
%
% inputs 6 - 5 optional
% data input data (MxN) (# axes (M) x # data sets (N)) class real
% tle spider plot title class char
% rng peak range of the data (Mx1 or Mx2) class real
% lbl cell vector axes names (Mxq) in [name unit] pairs class cell
% leg data set legend identification (1xN) class cell
% f figure handle or plot handle class real
%
% outptus 3 - 3 optional
% f figure handle class integer
% x axes handle class real
% o series object handles class real

Minor bug with automatic placement of legend (may cover the axis labels). Legend can be moved manually.

• MATLAB release: MATLAB 7.4 (R2007a)

Brilliant, well commented and very nicely done

Thank you Linus

If you have any ideas on improving the function or the calling of the function, I would like to know. The passing of the axis labels, units, data set labels, etc. is a bit clunky but I could not think of a better method. I am hoping that as others use this someone with get an inspiration.

very nice... Didn't work initially as the 'chop' function seems to be obsolete in R2010a.

A few users with long legend labels have suggested replacing the location in the legend call (line 222) from ‘northeastoutside’ to ‘best’. This does improve appearance in some cases. I’ll leave it to the user to decide which placement to use.

Bravo. Exactly what I need. Thank you
