程序运行后出现了下面现象，
??? Error using ==> delete
Root object may not be deleted.

Error in ==> specgraph.stemseries.stemseries>LdestroyBaseLine at 81
        delete(baseline);

??? Error using ==> delete
Error occurred while evaluating listener callback.

出错段函数为function LdestroyBaseLine(hSrc, eventData)
if ishandle(hSrc)
  parent = handle(get(hSrc,'Parent'));
  if strcmp(get(parent,'BeingDeleted'),'off')
    baseline = hSrc.BaseLine;
    if ishandle(baseline)
      peers = find(parent,'BaseLine',baseline);
      if isequal(peers,hSrc)
        delete(baseline);
      end
    end
  end
end



希望得到的结果如图，图像开始时的电磁波名称diancibo是怎么得到的。。。，我的结果是untitled，求教。。
