V12 tide stations
Have previously used the Harmonic tide file for local tide stations.
I see with Navionics, it uses the Navionics tide station icon and displays current height and direction.
If I right click and select the station, the popup window just has date and days but no graph or tide data.
How do you get the high/low data and/or graphing to display?

Re: V12 tide stations
Thanks Nick, that displays in data form.
So in the right click pop up menu, Tides:Station name this is no longer functional? Or does it work with a different dataset than the Harmonics?

Re: V12 tide stations
FYI be aware that the Navionics reported tides could be very different to actual. Using Lucinda Offshore station in North QLD,I have just noted some major discrpencie in tide stations using V12 and Navionics. Not sure what the refernce for the tides was using query object on tide station on chart. Tides query referenced Xtides Harmonics file
If I query the tide station from Navionics (Query object) for Lucinda, FNQ

I checked some other station data in area (Townsville) and the same sort of differences seen. It is like the tides displayed in Navionics query are 12 hours ahead of reality,
The time offset on object query seems to be correct (10) and the Height (0.94 increasing) is actually similar to what Austides says but the times are wrong. Maybe the object query displayed times are in UTC??

Re: V12 tide stations
Yes, they are in UTC.
I left them that way because there were some time zone discrepancies. Will investigate again ...
