pcolor: too many input arguments when called twice

I have a gui file 'window.m' in which a pseudocolor plot is created after the certain button is pressed. When I press this button for the first time, everything works correctly. When I press it for the second - I get an error:

Error using pcolor (line 46)
Too many input arguments.

Error in window>plotting_Callback (line 191)
h=pcolor(axesHandle1,x,x,sur);

Error in gui_mainfcn (line 96)
        feval(varargin{:});

Error in window (line 42)
    gui_mainfcn(gui_State, varargin{:});

Error in @(hObject,eventdata)window('plotting_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating uicontrol Callback

It's hard for me to understand why 'pcolor' has too many input arguments when called for the second time. What may be the possible ways to solve the problem?

Paste the segment of your code. This information is incomplete.

[Sergei]

function plotting_Callback(hObject, eventdata, handles)
<...>
acc=1000;
x=-25:50/acc:25;
axesHandle1= findobj(gcf,'Tag','axes1');
h=pcolor(axesHandle1,x,x,sur);
<...>

'sur' is a 2-dimentional array

Vague possibility: another pcolor() has become established on the path. Use

which -all pcolor

Try inserting that just before the pcolor() call and see if the results differ between the two presses.
