Hi Gregg, to add more map Layers you need to drag a new or duplicate Makepoint calculation onto the visualisation pane.

If stuck, I wrote a 3 post blog series for Biztory on getting started with Map Layers, here: www.biztory.com/blog/tableau...

Great work Darragh!

You are welcome!

I couldn't find it yesterday, but I have just now. I saw it from Jorge Camoes Medium blog post: medium.com/visualizing-...

I'm moving out! I'll comeback once the hit 20!

Absolutely, my eldest is 11, turning 12 soon. So I think I'm on my way out of the 'golden age' and so find it difficult now.

I find it more and more difficult as my kids grow up. They stay up longer in the evening before going to bed, and so they start eating into "my" time and I find I have less time to do the stuff I want to do as a consequence. It's become an effort for sure.

Where was this! I want one!

Nice work Nicola! I particularly liked 4. About alternatives to Dual Axis. The intersection between two lines and the potential interpretation is something I am often guilty of overlooking.
