How to fix axis of plot while using callback for slider?

How do I fix the axis so they don't autoscale when using the slider I created? I have had a lot of problems getting the slider to work. By using set at the end, the slider updates the plot fluently though the code is not pretty. I know that I, in the set command, create the new plot to be displayed when moving the slider, but i can't seem to control either axis, legends nor title of the plot in the set command.

if true
% Create figure for containing the plots
f = figure;
% Rescale the traces
a = (max(x(z).data_A) ./ max(x(z).data_C));
b = (max(x(r).data_A(1:140)) ./ max(x(r).data_B(1:140)));
AB = x(y).data_A;
B = (x(y).data_B ./ (1 ./b));
A = (x(y).data_C ./ (1 ./a));
% Create room on the figure for the slider
ax = axes('Parent', f, 'position', [0.13 0.39  0.77 0.54]);
% The plot containing the pulses
plot(steps, AB, 'b', steps, B, 'r', steps, A,'k');
axis([1 200 -0.0015 0.0015]);
legend('AB','A','B')
title('Visual of pulses')
% Creating the slider
h = uicontrol('Parent',f,...
                  'Style','slider',...
                  'Position',[81,54,419,23],...
                  'value',y,...
                  'min',1,...
                  'max',M,...
                  'Callback', @sliderCallback);        
bgcolor = f.Color;
hl1 = uicontrol('Parent',f,'Style','text','Position',[50,54,23,23],...
              'String','1','BackgroundColor',bgcolor);
hl2 = uicontrol('Parent',f,'Style','text','Position',[500,54,23,23],...
              'String',M,'BackgroundColor',bgcolor);
hl3 = uicontrol('Parent',f,'Style','text','Position',[240,25,100,23],...
              'String','Trace','BackgroundColor',bgcolor);                                                                                              
set(h,'Callback',@(a,b) plot(steps, x(round(get(a,'Value'))).data_A,'b',...
                     steps,(x(round(get(a,'Value'))).data_B./(1./(max(x(r).data_A(1:140))./max(x(r).data_B(1:140))))),'r',...
                     steps, (x(round(get(a,'Value'))).data_C./(1./(max(x(z).data_A) ./ max(x(z).data_C)))),'k'))
end

Any tips would be much appreciated. Running MATLAB R2015b.
