How can I call a function to draw histogram in GUI?

Dear all; I have a function written below, this function supposed to provide me with a histogram, when i push the button it must give a histogram in axes1, how can i do that please? knowing that the gui file and the function are in the same folder:

function SingleAxle = ALS_Single( Class9_data )
directory=dir('*.Y07');
for K = 1 : length(directory)
    filename = directory(K).name;
    fileID = fopen(filename,'r');
    formatSpec = '%s';
    A_cell = textscan(fileID,formatSpec);
    A=char(A_cell{1,1}{:,:});
    A(find(isnan(A)))=0;

      [rows,columns]=size(A);

      if columns~=105
          ArrayTemp=zeros(rows,105);
          ArrayTemp(1:rows,1:columns)=A;
          A=ArrayTemp;
          A=char(A);
          A(isspace(A)) = '0';
      end
      Month_of_Data= A(:,14:15);
      M=Class9_data;

      figure
      SingleAxle=100*Class9_data(:,14);
      histogram(SingleAxle);
      xlabel('Weight in Kg')
      ylabel('Counts')
      month(K)=unique(str2num(Month_of_Data));
      months = month(K);
      title(['ALS for C9 Single For Month ',num2str(months)])
  end

Use this syntax from the documentation for histogram.

"histogram(ax,___) plots into the axes specified by ax instead of into the current axes (gca). The option ax can precede any of the input argument combinations in the previous syntaxes."

Pass the handle of the axes in the GUI as the first input and your data as the second.

i was trying to handle and pass like this but it is not working: it keeps saying reference to non existing field. this is my gui fpushbutton function:

% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
SingleAxle=100*Class9_data(:,14);
N= str2double(get(handles.SingleAxle, 'string'));
axes(handles.axes1)
ALS_Single (N);
h = figure();
histogram(h, N)

I modified it this way but still not working !!

% --- Executes on button press in pushbutton1.
function pushbutton1_Callback(hObject, eventdata, handles)
% hObject    handle to pushbutton1 (see GCBO)
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
handles.SingleAxle=100*Class9_data(:,14);
N= str2double(get(handles.SingleAxle, 'string'));
axes(handles.axes1)
h = figure();
histogram(ax,h,N)
