classdef bubblePieChart < matlab.graphics.chartcontainer.ChartContainer & ...        matlab.graphics.chartcontainer.mixin.Legend    % bubblePieChart Creates a bubble pie chart.    %   bubblePieChart(x,y,p) create a bubble pie chart with the specified    %   pie locations and data. The sizes of the pies are determined    %   automatically based on the pie data.    %    %   bubblePieChart(x,y,p,s) create a bubble pie chart with    %   the specified size for each pie in points, where one point equals    %   1/72 of an inch. s can be a scalar or a vector the same length as x    %   and y. If s is a scalar, the same size is used for all pies.    %    %   bubblePieChart() create a bubble pie chart using only name-value    %   pairs.    %    %   bubblePieChart(___,Name,Value) specifies additional options for    %   the bubble pie chart using one or more name-value pair arguments.    %   Specify the options after all other input arguments.    %    %   bubblePieChart(parent,___) creates the bubble pie chart in the    %   specified parent.    %    %   b = bubblePieChart(___) returns the bubblePieChart object. Use b    %   to modify properties of the plot after creating it.        % Copyright 2020-2021 The MathWorks, Inc.    properties        % x-axis locations of the pies        XData (1,:) = []                % y-axis locations of the pies        YData (1,:) = []                % Pie data, specified as a matrix, where each row corresponds to        % the data for one pie        PieData {mustBeNumeric} = []                % Pie sizes, diameters in points (1/72 inch)        SizeData (1,:) {mustBeNumeric} = 50                % Line style to use for drawing pies        LineStyle {mustBeMember(LineStyle,{'-', '--',':','-.','none'})} = '-'                % Names of the pie categories        Labels (:,1) categorical = categorical.empty(0,1)                % Title of the plot        Title (:,1) string = ""                % Subtitle of the plot        Subtitle (:,1) string = ""                % x-label of the plot        XLabel (:,1) string = ""                % y-label of the plot        YLabel (:,1) string = ""                % Mode for the x-limits.        % Note that it is not a dependent property since auto limits are        % set by the chart and not the axes        XLimitsMode (1,:) char {mustBeAutoManual} = 'auto'                % Mode for the y-limits.
