The easy answer: I would suggest using the built-in pan tool in the figure toolbar.

The slightly more complicated answer: Try adapting the following code to your GUI. Here, I am creating a plot of some random numbers and using 4 uicontrols for pan buttons.

function panfigure()

% Setup figure
figure;
plot(rand(10,1),rand(10,1));
ax = gca;
set(ax,...
    'Units','pixels',...
    'Position',[140 100 400 300],...
    'XLimMode','manual',...
    'YLimMode','manual');

% Create pushbuttons for panning
uicontrol('Style','pushbutton','Position',[20 40 40 20],'String','Left','Callback',{@panleft,ax});
uicontrol('Style','pushbutton','Position',[100 40 40 20],'String','Right','Callback',{@panright,ax});
uicontrol('Style','pushbutton','Position',[60 60 40 20],'String','Up','Callback',{@panup,ax});
uicontrol('Style','pushbutton','Position',[60 20 40 20],'String','Down','Callback',{@pandown,ax});

end

% Callback functions
function panleft(obj,evt,ax)
    dx = diff(ax.XLim);
    ax.XLim = ax.XLim-0.05*dx;
end
function panright(obj,evt,ax)
    dx = diff(ax.XLim);
    ax.XLim = ax.XLim+0.05*dx;
end
function panup(obj,evt,ax)
    dy = diff(ax.YLim);
    ax.YLim = ax.YLim-0.05*dy;
end
function pandown(obj,evt,ax)
    dy = diff(ax.YLim);
    ax.YLim = ax.YLim+0.05*dy;
end

Does that help?

I can't run your code because I don't have data.xlsx, but I do not see why my panning routine would not work on your plot. Can you provide the error you are getting?

[Jonathan Vincent]

Illegal use of reserved keyword "end".

[Matthew Eicholtz]

Copy and paste the entirety of my code into a new file, save, and run it. It should not give any error. Once you see how the buttons work, you can insert them in your code appropriately.

[Matthew Eicholtz]

I think you received that error because you copied the middle part of the code (that includes an "end" statement), but not the function header. Is that correct?
