Stupid question from a novice! If I have a table which has several unique outlets (identified by a column called code) and for each outlet I have a seperate record (row) for each postcode together with a number of customers at that postcode how can I produce thematic maps of postcode points coloured (buffered!?) according to the number of customers at that point to create a heat map.
Can I do this for all locations at once or do I need to map each location seperately? Any help would be greatly appreciated.
