[AX,h1,h2] = plotyy(O,T,O,Q,'plot');[~,h3,h4] = plotyy(O,t,O,q,'plot');
双轴，q和Q一边，t和T一边，但是怎么设置线型来区分啊？
set(h1,'LineStyle','--','Color','r'); set(h2,'LineStyle',':','Color','k');
set(h3,'LineStyle',':','Color','m');
set(h4,'LineStyle',':','Color','c');
我用上面的程序，运行后说??? Error using ==> set
Invalid handle object.
求助各位大神
