for loop for generate overlay bar graphs
显示 更早的评论
I generated a bar graph of the following type:
load matrix.mat
matrix = matrix(1:2,:);
x = matrix(:,1)';
wR = 0.5;
wB = 0.6;
wG = 0.7;
wT = 0.8;
temp_R = matrix(:,2);
temp_B = matrix(:,3);
temp_G = matrix(:,4);
temp_T = matrix(:,5);
figure
barh(x,temp_T,wT,'FaceColor',[1,0,0.52])
hold on
barh(x,temp_G,wG,'FaceColor',[0,1,0])
barh(x,temp_B,wB,'FaceColor',[0,0,1])
barh(x,temp_R,wR,'FaceColor',[1,0,0])
hold off
I need to transform it so that the graph becomes this:
I tried the following code but it only works correctly for the last row of 'matrix' (i.e., for the value 67 on the vertical axis).
figure
barh(x,temp_T,wT,'FaceColor',[1,0,0.52])
for K = 1:height(matrix)
matrix_only_row = matrix(K,:);
if matrix_only_row(1,2) > ( matrix_only_row(1,3) && matrix_only_row(1,4) )
if matrix_only_row(1,3) > matrix_only_row(1,4)
hold on
wR = 0.7;
barh(x,temp_R,wR,'FaceColor',[1,0,0])
wB = 0.6;
barh(x,temp_B,wB,'FaceColor',[0,0,1])
wG = 0.5;
barh(x,temp_G,wG,'FaceColor',[0,1,0])
hold off
elseif matrix_only_row(1,4) > matrix_only_row(1,3)
hold on
wR = 0.7;
barh(x,temp_R,wR,'FaceColor',[1,0,0])
wG = 0.6;
barh(x,temp_G,wG,'FaceColor',[0,1,0])
wB = 0.5;
barh(x,temp_B,wB,'FaceColor',[0,0,1])
hold off
end
end
end
What do I need to modify to get the desired result?
If there is a more direct way it is appreciated.

load matrix.mat
[data,idx] = sort(matrix(:,2:end),2,'descend');
[n,m] = size(data);
colors = [1 0 0; 0 0 1; 0 1 0; 1 0 0.52];
max_bar_width = 0.8;
min_bar_width = 0.5;
bar_widths = linspace(max_bar_width,min_bar_width,m);
for ii = 1:n
for jj = 1:m
patch([0 0 data(ii,jj)*[1 1] 0],matrix(ii,1)+bar_widths(jj)*0.5*[-1 1 1 -1 -1],colors(idx(ii,jj),:));
end
end

Yes, simply use:
max_bar_width = 0.9; min_bar_width = 0.3; bar_widths = linspace(max_bar_width,min_bar_width,m);
