multivariate map (多变量映射图)

bivariate/ternary choropleth map (双变量/三变量映射图)

multiData=load('multi2_3.mat');
X1=multiData.X1;
X2=multiData.X2;
A=multiData.A;
B=multiData.B;
C=multiData.C;

% 先绘制一个没有赋予颜色的图形
% First, plot a figure without assigning colors.
surfHdl=surf(X1,X2,zeros(size(X1)),'EdgeColor','none');
hold on;view(2);axis tight

% 调用工具函数生成图例和映射表
% Call utility functions to generate the legend and mapping table.
[CMapData,CMapHdl]=multiVarMap3(A,B,C,'colorList',1,'pieceNum',8);
set(surfHdl,'CData',CMapData);
