How to Fit Plot into Axes

Hello, I'm very new to MatLab since I have exactly 2 days of using it. I began to get familiar doing and modifying some coding. Hoewever, I'm having trouble fitting a plot's output into the axes created at the GUI. I attach code and screenshot below) I wanna know how to make them fit in to the axes without the plot doing what it likes. Thank you very much in advance.

function pushbutton1_Callback(hObject, eventdata, handles)
sliderVal1=get(handles.Prslider,'Value');
Pr = [sliderVal1]; % Choose Prandtl
sliderVal2=get(handles.NusselSlider,'Value');
 etaMax = [sliderVal2]; % Choose etaMax
 sliderVal3=get(handles.lengthslider,'Value');
 xm = [sliderVal3];
    solinit = bvpinit(linspace(0,etaMax,8),...
        [0, 0, 0, 0, 0]);
    sol = bvp4c(@BlasiusT, @BlasiusTbc,...
        solinit, [], Pr);
    eta = linspace(0, etaMax);
    y = deval(sol, eta);
    subplot(2, 1, 1);
    plot(eta,  y(1,:),'--k',eta,y(2,:),'-k',eta,...
        y(3,:),'Color',[0.9,0.1,0.1]);':k';
    xlabel('\eta');
    ylabel('y_1, y_2, y_3');
    legend('Stream function f = y_1',...
        'Velocity, df/d\eta = y_2', ...
        'Shear, d^2f/d\eta^2 = y_3');
     subplot(2, 1, 2);
   plot(eta, y(4,:), '--k', eta, y(5,:), 'Color',[0,0.1,0.9]);':k';
    axis([0 xm 0 2]);
    legend('Temperature, T^* = y_4',...
        'Heat flux, dT^*/d\eta = y_5');
    xlabel('\eta');
    ylabel('y_4, y_5');

Before, set up with

pan1 = uipanel('Units','normal', 'Position', [0 0 3/4 1]);

and place the sliders outside this region. You might find it easier to create a second uipanel to put the sliders in.

Then with that set up, you can do your calculations and then

ax1 = subplot(2, 1, 1, 'Parent', pan1);
plot(ax1, eta,  y(1,:),'--k',eta,y(2,:),'-k',eta,...
      y(3,:),'Color',[0.9,0.1,0.1]);':k';
xlabel(ax1, '\eta');
ylabel(ax1, 'y_1, y_2, y_3');
legend(ax1, 'Stream function f = y_1',...
      'Velocity, df/d\eta = y_2', ...
      'Shear, d^2f/d\eta^2 = y_3');

   ax2 = subplot(2, 1, 2);
   plot(ax2, eta, y(4,:), '--k', eta, y(5,:), 'Color',[0,0.1,0.9]);':k';
   axis(ax2, [0 xm 0 2]);
   legend(ax2, 'Temperature, T^* = y_4',...
        'Heat flux, dT^*/d\eta = y_5');
   xlabel(ax2, '\eta');
   ylabel(ax2, 'y_4, y_5');
