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

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.
