Store improfile data issue

Hi,

I am using the code below to get the intensity profile plot data (Typically zero is taken to be black, and 255 is taken to be white) and I have a a problem that I will appreciate the help:

- The improfile plotted on the image is a mirror of the the data stored intensitySet (I wish my stored profile to start from left to right). Therefore, why and how can it be fixed?

Thanks

Code:

clc;
clear;
I = imread('liftingbody.png');
xline = [100, 300];
yline = [300, 300];

% line([x1,x2],[y1,y2]), not line([x1,y1],[x2,y2]);

imshow(I)
hold on; 

line(xline,yline)

improfile(I,xline, yline);
[cx,cy,YofIntensity]=improfile(I,xline, yline);

Xindex = zeros(size(YofIntensity), 1, 'double')
for i=1:size(YofIntensity)
    Xindex(i)=i;
end

intensitySet = horzcat(Xindex, YofIntensity)
figure(2);
plot(Xindex, YofIntensity)

Set the ydir property of the axes to 'normal' or 'reverse' to flip the plot of the data:

set(gca,'YDir','reverse')
