MATLAB 2016a进度条对象获取和设置问题
ha1=get(hrand,'Children');
hac=get(ha1,'Children');
hapa=findall(hac,'Type','patch')
set(hapa,'FaceColor','k')
这个程序在2014a以前都可设置进度条的颜色，我换成MATLAB2016a之后，
hac=get(ha1,'Children');运行显示 0x0 empty GraphicsPlaceholder array.；
而且set也不能设置颜色了，望指教

Why Is the Children Property Empty for Some Objects?
Starting in R2014b, these objects do not contain handles to underlying objects in their Children properties. To customize the graph, use properties of the actual object. This table lists the affected objects.
这个我也查了，我是想知道在2016a中如何设置啊，可否告知
Use colorbar properties to modify the colorbar.

hrand=waitbar(0.3,'颜色')
ha1=get(hrand,'Children');
hac=get(ha1,'Children');
hapa=findall(hac,'Type','patch')
set(hapa,'FaceColor','r')
我还是不懂，就是您能否设置一下进度条的颜色hrand=waitbar(0.3,'颜色')，在2016a中，这个程序在2014a以前都可以把进度条颜色设置为红色，但是2016a中帮助文档说是colorbar但是我还是不会设置进度条啊
