multiple annotation in one line

Friends

  1. Excuse me if this questions is posted already. I have to make 5 to 6 annotations in my figure. Is there any way that i can make all of them in one shot instead of writting a separate line of code for each of them.

for instance plot function accepts a series of x,y data. Is it possible with annotate function also.

  1. Is it possible to use an axis range to place a text. Ie we use a something like xy=(160,0) to indicate the axes positions where the text should be placed, instead i want specify for instance x-axis range 160-180 and place the text in the center of this range.

Thanks,
Bala
