Also, logarithmic factor (>=2) for the scaling is added, with a default value of 10 ('logfactor',10)% Added the possibility to manually define the frequency grid manually by using 'freqs',[10 20 40 70 100] (note that the values must be specified as a percentage, rather than a fraction of 1). Frequency=0 is always shown.% Added a new "Others" output, to retrieve the frequency grid (in case it is modified when using logarithmic scale)% Default 'freqround' has been changed from 1 to automatic.% 2023/Feb/06 - Added option to normalize the extension of the sectors/arms/patches => 'normalize',true will display all the sectors with full length, and the relative frequency of each sector on the outside.% Added minimum radius circle to the plot (now, with the gap option, it is necessary)% Changed histc function for a custom line of code to determine the speed bins. This avoids problems with backwards compatibility and the warning message of using "histc" instead if histocunts. The custom function does exactly the same as in previous versions, so the result does not change at all.% Checked and rechecked that the "AngleNorth" and "AngleEast" reference angles affect the output at desired, even with angles different to 0-90-180-270deg. Please check the data, the function call and the resulting figure and table before posting a comment/request on this. % 2023/Jan/31 - Added documentation for legendPosition and legendOrientation, correcting legendOrientation for colorbar legends.% 2023/Jan/25 - Thanks to Clive Holden from Oceanographic Field Services for funding these changes% Added ability to change text color, fontname, fontweight, fontangle and size independently for each type of text (Title, axes label, frequency labels, legend, colorbar)% Added the possibility of leaving a gap between arms/patches/sectors of the Wind Rose => use 'gap',x where x is a fraction of the angular spawn of the actual angles covered. gap=0=>No gap; gap=1=>all gap & no windrose.% Opacity of the face and edge of the windrose can now be changed using 'FaceAlpha' and 'EdgeAlpha' respectively (only if this is allowed by your matlab version, otherwise a warning message will appear).% The last speed bin (>X) now shows values, because when sorting the speeds and the bins, the maximum value is omitted now, so >X has values inside.% The default variable name has been changed from W_S to u_w% Using inverted colormaps with invcolormap should be called from now on using inv_colormap to prevent conflicts with colormaps actually starting with inv. Using inv is still maintained to keep backwards compatibility, but a warning is shown.% Corrected an error on radial grid placement. The radial grid now starts placing from 90deg trigonometric, to match the label placement. It previously started at 0deg trigonometric (3 o'clock), so it did not match with the label placement, which started at 90deg trigonometric (12 o'clock). This was noticeable when not using a number of labels or radial axes multiple of 4.% 2022/Aug/14 - Thanks to JoséMiguel Jáuregui and NAYXA for funding the following changes% Added 'analysisMode' (true/false): 'analysisMode',true will not show the figure. It will only creates the tables and output arguments of the function.% Extra output added: Others (Structure including: MaxFrequency shown in axes, nFrequencies (number of Frequencies) shown). Access these using Others.MaxFrequency, Others.nFrequencies, ...% Combining AnalysisMode and new output is useful to normalize limits and wind speeds of several windroses.% Added 'legendPosition' option. Valid values are: 'northwest' (default for box legend),'north','northeast','west','east' (default for colobar legend),'southwest','south','southeast'; Colobar legend only accepts 'north','east','south','west'% Added 'legendOrientation' option. Valid values are: 'vertical' (default) and 'horizontal'% 2022/Jul/04 - Possibility to change edgecolor of the patches. ('edgecolor','normal') is the default, with slightly darker edges. Any other color option can be used: ('edgecolor','none') or ('edgecolor','k') or ('edgecolor',[0 0.3 0.5])% Colormap can now be input using 'colormap' and 'colmap', not only 'cmap'% 2021/Jun/08 - Frequency labels shown by default in the best position% Thanks to Josselin Gautier for these ideas:% Added option to change frequency font size ('FrequencyFontSize',N), N beign a valid font size value% Added option to change patches line width ('edgewidth',N), N being a valid linewidth value% Added option to show patches in front of the grid ('plotontop',true)% 2021/Apr/20 - Thanks to Jacqueline Freire Rigatto for the idea of adding option to show frequencies as in a ruler% Added a space below the title string so it does not interfere with the upper label% Added the variable name into legend type 1 (colorbar)% 2020/Mar/04 - Added option to plot the windrose in the desired position (X,Y) in a plot. This is very useful combined with scalefactor.% 2020/Mar/03 - Changed the way in which labels are read. The order now should be 'North','East','South','West'.% Added options for grid line styles (color, line style and transparency/alpha) both for radial and circular grids.% Added option for variable adial divisions.% New angular-label options, now the function is able to support several labels in form of a cell array, which will be equally spaced.% cMap now allows a Nx3 array of colors, which will be interpolated for the number of speeds shown (previously, the only option was to put these colors into 'colors' with a number if colors matching the 'nspeeds')% Added ability to change text, title and legend font through 'textfontname', 'titlefontname' and 'legendfontname' respectively% Added option to show frequency labels in the best place possible, with 'auto' option for 'freqlabelangle'% Added ability to plot zero and negative data% 2015/Jun/22 - Corrected histogram count inside function "PivotTableCount", which didn't consider always values greater than the max(vwinds) value.% 2015/Mar/13 - Added option to represent windrose inside given axes handle% 2015/Feb/22 - Corrected small errors.% Created extra documentation.% Corrected help dialog% 2014/Jul/28 - Figure has options to hide/show menubar and toolbar. Default is that menubar and toolbar are shown.% Default min_radius is 1/15 instead of 1/30.% User can specify speed bins 'colors' (necessary that nspeeds or vwinds are specified)% Order of the speeds can be modified: lowest speeds inside ('inverse',false) -default- or lowest speeds outside ('inverse',true)% Speed bins can be explicitly defined ('vwinds'), instead of just defining the number of the speed bins% Corrected bug when showing colorbar ('legendtype',2) with cmap other than jet% All options can now be passed to the function into a single cell array or a structure, where fieldnames are the property to be modified.% 2014/Jul/14 - First version%%%% by Daniel Pereira - daniel.pereira.valades@gmail.com - https://dpereira.asempyme.com/windrose%% Check funciton callif nargin<2error('WindRose needs at least two inputs'); % function needs 2 input argumentselseif mod(length(varargin),2)~=0 % If varargin are not pairedif (length(varargin)==1 && isstruct(varargin{1})) % Could be a single structure with field names and field values.varargin = reshape([fieldnames(varargin{1}) struct2cell(varargin{1})]',1,[]); % Create varargin as if they were separate inputselseif (length(varargin)==1 && iscell(varargin{1})) % Could be a single cell array with all the vararginsvarargin = reshape(varargin{1},1,[]); % Reshape just in case, and create varargin as if they were separate inputs.elseerror('Inputs must be paired: WindRose(Speed,Direction,''PropertyName'',PropertyValue,...)'); % If not any of the two previous cases, errorendelseif ~isnumeric(speed) || ~isnumeric(direction) % Check that speed and direction are numeric arrays.error('Speed and Direction must be numeric arrays.');elseif ~isequal(size(speed),size(direction)) % Check that speed and direction are the same size.error('Speed and Direction must be the same size.');end%% Default parameters
