Text in plot that has x-axis in terms of datetime

Hello,

I have a plot that uses a datetime structure as an x axis and I want to add a text string on my plot. Typically I would do that using text(x,y,'text'). In this case I am not sure what I would use as 'x'. The 'annotation' command uses normalized values that do not move when I zoom or pan the plot. Would appreciate some input on what I would use as my 'x' in the text function. Thanks!

I just had this problem and I could position the text using datenum in this way:

text(datenum( the_date ), y_axis_val, text)

A date number of the time x. Same idea as with ordinary axes; the date axes is one with the limits based on the first/last date of the x vector. You can retrieve these from the plot as

xlohi=xlim;

then scale between those two at whatever point you wish would be one way...
