Tom, Thanks for your response, however, it didn't quite answer my question. The attached file is a screen shot of the legend of the piper that I created. there are three stations (represented by orange squares, green circles and blue stars) with annual data for each. I want the legend to show only three symbols (one for each station) such that it reads: station 1 (orange square), station 2 (green circles), and station 3 (blue star), rather than show a symbol for each annual result (as in the attached) can I do this with GSS or Gtplot?

I am a begginner user of the GWB. I created a GSS file of annual (2006 to 2010) water quality data for various sampling stations for a site. When I launch Gtplot (to create a piper of these data) the plot creates a different symbol for each data point. While i am able to modify the symbols so that data from the same station are represented by the same symbol, I would rather be able to group points together so that GWB "knows" they are from the same well, because, in presenting the data I would like to have a legend that shows a symbol for each station rather than each result. Is there a way to group data? If I have not described my problem sufficiently or clearly I'd be happy to elaborate. Thanks for any help in advance. Laura
