Hi, a very minor thing: I just checked in the latest snapshot the new convention and wording of the shading example file. The minor glitch is that it says the dates have to be in the format "YYYY:MM", even though I opened it with quarterly data (for example). So I suggest that it should be amended with "(or YYYY:Q, or YYYY, or YYYY:MM:DD)" or whatever else is possible. thanks, sven
