Save a plot to a graphics format file

I am designed the following GUI where there are an axes. I want to save the plot drawn inside them to a graphics format file. However, the file obtained is an image of the overall figure window. This is my code:

X = 0:pi/100:2*pi;
Y = sin(X);
fh = figure;
Pan1 = uipanel(fh,'Units','normalized','Position',[0 0 0.5 1],'title',...
    'Panel1');
Pan2 = uipanel(fh,'Units','normalized','Position',[0.5 0 0.5 1],'title',...
    'Panel2');
haxes = axes('Parent',Pan2,'Units', 'normalized','Position',...
    [0.25 0.25 0.5 0.5]);
hplot = plot(haxes,X,Y);
FileName = uiputfile('*.bmp;*.png;*.jpg;*.tif','Save as');
saveas(hplot,FileName);

Although,it's about 3 or 4 years along this thread,but I faced the same problem ,and I have found the solution,So I will put it here may it will help any one ,one day

    axes(handles.axes3);
A = getframe(gca);
[filename,pathname]=uiputfile({'*.png';'*.jpg'},'Save Image as','C:\untitled.png');
name=fullfile(pathname,filename);
imwrite(A.cdata,name);
%check for the existence of the file and displays a message about the result of the file selection operation.
if isequal(filename,0) || isequal(pathname,0)
   return;

Thank you norhan Mohamed..I could solve my issue with your code

I should have warned of this earlier. Beware of using norhan's code. It only works if there is no scaling/zooming/fitting of the image to the axes. To illustrate that, just run this code:

rgbImage = imread('C:\Program Files\MATLAB\R2018a\toolbox\images\imdata\concordaerial.png');
imshow(rgbImage);
size(rgbImage)
A = getframe(gca)

You'll see

Warning: Image is too big to fit on screen; displaying at 33% 
> In images.internal.initSize (line 71)
  In imshow (line 336)
  In test5 (line 10) 
ans =
        2036        3060           3
A = 
  struct with fields:

         cdata: [679×1020×3 uint8]
      colormap: []

Note how the size goes from 2036x3060 to 679x1020?

So A.cdata is not the same size as the original image!

It is the displayed size.

Ah yes, finally our daily "how do I save a figure?" question. Please refer to the FAQ: http://matlab.wikia.com/wiki/FAQ#How_do_I_save_my_figure.2C_axes.2C_or_image.3F_I.27m_having_trouble_with_the_built_in_MATLAB_functions. where you'll see reference to the most downloaded File Exchange submission, export_fig(). Just use that and simplify your life. Braving it alone with low level MATLAB code is not for the faint of heart or novices, and often causes problems as you now have seen.

@Image Analyst: Thank you so much for your answer.

Most easy way is to make a print:

print( h, '-djpeg', 'test.jpg');

It will print the current view of the plot to your workspace....

@Ben: Thank you for your answer. However, I have tried it adding

print(hplot,'-djpeg',FileName);

to my code but it does not work.
