In actual analysis scenario, when you need to analyze data according to geographical domain, you can directly use the map to pass a lot of geographic information, it is difficult to highlight the data information you want to express.
How to more highlight data information and ignore geographic information? Use a hexagon mesh map (cellular map) will be a good choice.
As shown in the figure below, each hexagon represents a geographic area (example as China), each region is based on its substantially geographical distribution, and it is easy to obtain data conclusions through color.
So, how to implement a hexagon mesh map in Tableau, share the method today!
The Tableau tricks we want to share with you this issue are: Use space files to achieve a hexagon mesh map (cellular map).
For the convenience of learning, chestnuts use Tableau to own the "example-supermarket" data source. After mastering the chestnut method, the data powder can try to use its own data.
Specific steps are as follows:
1, make spatial files
Making space files, as shown below (Take Geojson as an example):
2, connection space file
Open Tableau Desktop to connect to the "example-supermarket" data source that comes with Tableau.
Next, add the spatial file just made.
In the data source work interface, the connection mode is modified to the right connection.
Tips: Note the following when connecting space files!
3, create chart
New worksheets, double-click the metrics "geometry" in the "Data" pane.
Then, drag and drop the dimension "provincial / autonomous region (hexagon mesh)" to "Tag" "" tag and "detailed information", and drag and drop the metric "Marker" card. .
Click on the top menu bar "Map" - "Map Layer", on the left "map layer" pane, adjust "Error" in the "Background" to 100%:
Click "Color" of the "Mark" card to change the "boundary" in the "Effect" in the pop-up window. Then, click Edit Colors, in the Edit Color [Profit] dialog box, change the color to "Red - Green - Golden Dissu", click OK.
In this way, the hexagon mesh map is completed.
