使用“for”语句同时显示两个动画的八度
使用“for”语句同时显示两个动画的八度
提问于 2021-06-01 11:58:23
我想动画的TOF分光计(飞行时间质谱)使用'for‘语句。我可以制作一个脚本，动画中的离子在试管内飞行。这是一个脚本：

print primjer_tof_ms2.png现在，我也想加入一个光谱图，当离子飞到探测器上。光谱是洛伦兹函数的总和，当特定离子到达探测器时，洛伦兹函数在时间矩上具有峰值。我制作了一个剧本，只为这个情节动画片：

ht = title(['t = ' num2str(t(k)) ' s']);

title(['t = ' num2str(t(k))]);但是当我试图组合这两个代码时，在第一次迭代之后，只有谱图继续活到结束，而以离子作为图形对象的图形停止了。我试图将这两个情节放在相同的“for”循环中：

您将在循环的每一次迭代中使用以下行创建axes
axes ("position", [0.5, 0.67, 0.2, 0.17]); 这也将它们设置为当前的。然后，当你做你的rectangle的事情时，这些矩形被画在你为光谱创建的小轴上，这些小轴被你创建的新矩形所覆盖。您使用axis equal;隐式创建的第一个轴始终未使用。
相反，您应该在循环之外创建图形对象，并在其中使用对它们的引用。大多数绘图函数都可以接受轴的句柄作为其第一个参数。也可以在调用绘图函数之前显式设置当前轴。最小的实例是：
h = figure;
ax1 = axes('position',[.1,.5,.4,.4]);
ax2 = axes('position',[.5,.1,.4,.4]);
v = -10;
wmin = 0; dw=0.1; Wmax = 6*pi();
w = [wmin:dw:Wmax];
t0 = 0; dt = 0.01; T = 10;
for t = t0:dt:T;
x = w/Wmax .*cos(w+t*v);
y = w/Wmax .*sin(w+t*v);
plot(ax1,x,y);%specificaly plot to ax1 (also sets it as current)
axes(ax2)%set ax2 as current axis
plot(w,x,w,y);%plot to the current axis
pause(0.1)
end此外，还有一些依赖于所选图形工具包和八度版本的警告、意外行为或bug。我在尝试代码时遇到的一个问题是，title对象会被plot破坏，所以您必须重新创建它，而不是更新它的text属性。我隐约记得在其他与八度绘画有关的情况下，我不得不求助于其他的变通方法。因此，理解它应该如何工作可能会有所帮助，让文献资料读一读从长远来看可能是值得的。我会推荐其他的但这就是我所拥有的。
由于我已经开始通过尝试您的代码来回答问题，所以您可以得到一个稍微更有用的版本。不过没有保修。
