hello, I have this data

I am using the following code to draw the rectangles from the data, the first column is the length and the height is the second column - third column.

drawingfunction(BodyData);
function [] = drawingfunction(BodyData)
figure('Name','BodyView');
hold on
for i =1:1
    MD = BodyData{i,1};
    MD(:,1) = MD(:,1);
    a = size(MD,1);
    for j =1:(a-1)
        coord = MD(j:j+1,:);
        r = rectangle('Position',[coord(1,1) coord(1,3) coord(2,1)-coord(1,1) coord(1,2)-coord(1,3)])
        axis([0 0.2 -0.1 0.2])
        hold on
       end
    
end
end

The code is running okay here is the result attached:

Now I want to mirror this image using x axis as the axis of mirror

does anyone has an idea how to do it?

I solved it

drawingfunction(BodyData);
function [] = drawingfunction(BodyData)
figure('Name','BodyView');
hold on
for i =1:1
    MD = BodyData{i,1};
    MD(:,1) = MD(:,1);
    a = size(MD,1);
    for j =1:(a-1)
        coord = MD(j:j+1,:);
        r = rectangle('Position',[coord(1,1) coord(1,3) coord(2,1)-coord(1,1) coord(1,2)-coord(1,3)])
        axis([0 0.2 -0.1 0.2])
        hold on
        % magic Line hich solves the problem
        rectangle('Position',[coord(1,1) -coord(1,2) coord(2,1)-coord(1,1) coord(1,2)-coord(1,3)])
        axis([0 0.2 -0.1 0.2])
        hold on
       end
    
end
end
