This is what I'm getting: . generate date1=date(date,"MY") . format date1 %tm . list date1 date in 1 +------------------+ | date1 date | |------------------| 1. | 3469m3 Aug2009 | +------------------+ What am I doing wrong? Thanks, Ana On May 24, 2011, at 2:18 PM, Nick Cox wrote:

But my version is not working (I still get the invalid label specifier message). Could it be because my time variable has gaps? Also, how can one setup the "11" in your for loop without having to make mental calculations regarding the number of months? Thanks for the help! Ana On May 24, 2011, at 1:31 PM, Nick Cox wrote:Yes.

For Stata 8 see update from 12 September 2003." In fact the techniques there do remain useful for some problems. Here's an example with different data. Here I decide that I want labels every 2 months from 1 January 2002 to 1 January 2003. I loop over the dates and put them in a bag, namely a local macro. sysuse xtline1 xtset person day forval i = 1(2)11 { local thisdate = mdy(`i', 1, 2002) local mydates `mydates' `thisdate' } local thisdate = mdy(1,1,2003) local mydates `mydates' `thisdate' xtline calories, overlay xlabel(`mydates', format(%d_m_Y) ang(v)) See alsoSJ-7-4 gr0030 .
