matlab中画一条折线时怎样显示出每个点折点的数值

举个例子：

num=[5,44,62,154,264,365,398,480,619,705,762,728,669,726,890,731,707,696,558,509,444];
date=[1.20,1.21,1.22,1.23,1.24,1.25,1.26,1.27,1.28,1.29,1.30,1.31,2.1,2.2,2.3,2.4,2.5,2.6,2.7,2.8,2.9];
time=1:1:21;
plot(time,num)
text(time,num,num2str([date;num].‘,‘(%.2f,%d)‘))
