Maps & Postal Codes [UK]
Hi Lin
thanks for the reply but unfortaunly it is proving to be not as simple.
I have a list of 90k+ people and their postcode through the south west of the UK yet my heat map and other settings only show them within the area shown on the image below......?? Very confused.
I'm not sure if this will help you or not Anonymous , but I reckon there's some sort of unexpected behaviour (I won't call it a bug!) going on here - as I've recreated your issue using standard post code data with a dataset of just over 138,000 postcodes.
Filtering the dataset down to Wales, and using lat/long pairs as my location data - I get a reasonable map back. There's an i symbol at the top of the screen that states it's "Showing significant data points".
However, when I use postcodes as my location field (regardless of their format) then I get a limited number of post codes rendered on my map and the i symbol states that there are "too many pcds values". As you can see from the screenshot, it only renders Cardiff and then it gives up rather than providing a representative sample for Wales as in the previous map. So the visual behaves in an inconsitent and unexpected way depending on the data used for location - or i'm missing a setting. I don't think I am, as i copied the first visual and changed data source as well as scouring the visual settings looking for a reason.
What happens when you click on the i in you'r screen shot?
