Like this?

function guiSample()
h = figure;
uicontrol(...
  'Parent',   h,...
  'Units',    'normalized',...
  'Position', [0.1 0.8 0.4 0.1],...
  'String',   'Push!',...
  'Callback', @Callback_pb);
ax = axes(...
  'Parent',   h,...
  'Units',    'normalized',...
  'Position', [0.1 0.1 0.8 0.6]);

function Callback_pb(~,~)
  plot(ax,magic(4))
end
end
