Please help me how to execute evalin function in GUIs Callback.
For example (it is only part of code, I konow in this case I don't need to use evalin, it's just simple example of my problem ;):

function pushbutton_time_series_Callback(hObject,eventdata, handles)
t = getappdata(gcf,'t');
x1 = getappdata(gcf,'x1');
whos
evalin('caller','plot(t,x1)');

returns error:

??? Error using ==> evalin
Undefined function or variable 't'.

function whos swows that there exist t and x1

When this variables ale also in main Matlab workspace and i call

evalin('base','plot(t,x1)');

everything works perfectly, bui I mustn't use this (because of my professor, who wanrs me to keep all variables in GUIs workspace)

What in this case is 'caller'? I was sure that it was my callback function, bui it seems not...
