Open a replacement worksheet. during this data source, these fields are named Pickup Latitude and Pickup Longitude. make sure that the Pickup Latitude geographic role is assigned to your latitude field, an the Pickup Longitude geographic role is assigned to your longitude field.

The Latitude and Longitude fields are added to the Columns and Rows shelves, and a map view with one datum is made .
Now, let’s add distinct marks to the view. Select ID and place it on the small print mark. Because each pickup has its own ID, this breaks up the mark and distinguishes one pickup from another on our map.
There will be a warning letting you recognize that the sector added may contain quite the recommended maximum of 1000. Select Add all members.
The map view updates to point out marks for each pickup location in your data source. Since every location is within Manhattan, the map will zoom to specialise in Manhattan in ny City.
On the Marks card, change the mark type to density by selecting the menu to the proper of Automatic and choose Density.
Your basic density map is made . you’ll see that midtown is that the hottest area for taxi pickups in October, although you’ll adjust the main target further by using the zoom tool. Density will recompute as you concentrate or out.
