Tableau URLs for aviation stats.

The Pax (& PaxTextVn), dashboards now work with URLs to pass parameters, but it has been a dull process. Basically, in spite of what I read on forums and Tableau help, it does not seem to be possible to pass a space as %20. After many different attempts, I've just had to remove spaces from some data fields, and some parameter and field names.

So now, you can access the data directly with a URL such as:

https://public.tableau.com/profile/david.marsh#!/vizhome/Pax/LoadFactors&Year=2014&GeoDepLevel=Region&GeoDepLevelSelected=EU28&GeoDesLevel=Region

or 

https://public.tableau.com/profile/david.marsh#!/vizhome/Pax/DeparturePatterns&Year=2012

In the latter case, it's not yet simple to work out how to pass the airport parameter. Watch this space for improvements here.
