I'm unsure what you're asking for. Tableau will plot post codes (the first half - called a sort code) for the UK. You are unable to grab these from tableau to use elsewhere. Are you attempting to bring in your lat and long from somewhere else and built your own polygons? With some more information things might be made easier for myself or others to assist you.
Thanks for replay. I as to design polygon map. for designing polygon map I need two metrics POINTORDER, POLYGON NUMBER. Hw I can generate POINTORDER, POLYGON NUMBER metrics into my data using excel or any calculated column.
Are you able to show an example of your data. Its still incredibly vague
what you're looking to do and what you're looking to do it with. A former
colleague has used our software to use this demo. The software is free and
maybe it will help you understand the format and what point order and
polygon number give you. https://www.youtube.com/watch?v=6X2HofAUA3Y
