Dear All,
I have a daily data on stock returns and would like to plot the series together with their min and max values attached to their places on the line. Could you please suggest me any example?
Best

You would use GRTEXT for that (a separate GRTEXT for the max and for the min). If you do an EXTREMUM instruction on the series first, it will give you the entries for the max and min (%MAXENT and %MINENT) and the values (%MAXIMUM and %MINIMUM), which you can use to position the text. I don't see any examples with a time series graph, but the @THRESHTEST procedure does something like this for an x-y graph.

Dear Tom
Thank you for your prompt reply. I would like to also see the date for max and min. Is it possible?

%DATELABEL(%MAXENT) and %DATELABEL(%MINENT) will construct labels for the maximum and minimum entries. Note that the graph might look a bit cluttered if you try to put all that information on with the data lines.
