How can i set dynamic axis limits in GUI?

I want to create a map where I can set the upper axes limits with an editfield oder a slider.

 function edit_x_Callback(hObject, eventdata, handles)

 wert_x = str2double(get(handles.edit_x,'String'));

 if (wert_x < 100) wert_x = 100;
 elseif (wert_x > 10000) wert_x = 10000;
 end

 set(handles.edit_x,'String',wert_x);                
 set(handles.slider_x,'Value',wert_x);             

 set(handles.map,'Xlim','[0 wert_x]');

when editing the edit_x i get following errors:

 Error using matlab.graphics.axis.Axes/set
While setting the 'XLim' property of 'Axes':
Value must be a 1x2 vector of numeric type in which the second element is larger than the first and may be
Inf

 Error in uebung_slider>edit_x_Callback (line 122)
set(handles.map,'Xlim','[0 wert_x]');

 Error in gui_mainfcn (line 95)
        feval(varargin{:});

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

 Error in
matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)uebung_slider('edit_x_Callback',hObject,eventdata,guidata(hObject)) 
Error while evaluating UIControl Callback

How can I fix the problem?

Without quotes around the limits:

set(handles.map, 'Xlim', [0 wert_x]);

Make sure wert_x is greater than 0, get rid of the single quotes around the vector. The 'xlim' property of an axes is a numeric type, not a char type.

Thanks alot, it works now without the quotes.
