Attached is a Google Docs Spreadsheet for keeping track of water quality tests. The data columns have conditional formatting for parameter ranges. The graphs are on the far right.
If you try exporting to convert to OpenOffice, we have found the format does not seem to include the graphs if you import it into LibreOffice. And we haven't tried exporting to the Excel format as we don't have Windows to test it on.
