回答： Kiran 2016-2-10

I am trying to plot three different scatter3 plots on a figure and have one legend for all three figures. I have written some generic code to replicate my data set. The difference for each figure should be the value in each column of w, (as shown by the code for each figure below). Any help is appreciated!

w=[randi(2,50,1),randi(3,50,1),randi(5,50,1)];
x=repmat((1:10)',5,1);
y=repmat((1:3:15)',10,1);
z=[ones(10,1);ones(10,1)+1;ones(10,1)+2;ones(10,1)+3;ones(10,1)+4];
p=rand(50,1)*75;
c=w(:,1);
%Figure 1
cVals=unique(c);
for i=1:length(cVals)
    indices=find(c==cVals(i));
    scatter3(x(indices),y(indices),z(indices),p(indices),'filled');
    hold on
end
%Figure 2
c=w(:,2);
cVals=unique(c);
for i=1:length(cVals)
    indices=find(c==cVals(i));
    scatter3(x(indices),y(indices),z(indices),p(indices),'filled');
    hold on
end
%Figure 3
c=w(:,3);
cVals=unique(c);
for i=1:length(cVals)
    indices=find(c==cVals(i));
    scatter3(x(indices),y(indices),z(indices),p(indices),'filled');
    hold on
end
