Hello, I have this data

the first column is the start and end points of the rectangle and the height of the rectangle is the second column - third column is at that point.

The code which I am using to plot it is this

for i =1:1:1
  MD(:,1) = MD(:,1)
    a = size(MD,1);
    for j =1:1:(a-1)
        coord = MD(j:j+1,:);
        rectangle('Position',[coord(1,1) 0 coord(2,1)-coord(1,1) coord(1,2)-coord(1,3)])
         axis([0 0.2 -0.1 0.2])
        hold on
    end
end

It is not working,

does anybody knows ?

在 MATLAB Online 中打开

I think, one for loop is sufficients

%Read the file xlsx or CSV
for loop to read the individual row 
row_data=data; % Please ensure mat /array 
figure,
data=[0,0.0480,0.0380]
rectangle('Position',[data,data(3)]);
%.............................^ set this points as approprite
axis([0 0.09 0 0.9]); % Set the axes positions, so that small ractangle also visible 
hold on;
end
