You can import a simple spreadsheet with postcodes and labels or a more complex CSV file with more than two columns.

Editing your data

From the Add your own data tools, you can: modify the point markers and data labels individually or in groups of equal values.

Point markers

From your CSV file, choose the data that you want to display and a different point marker to symbolise each of your individual data or group of data.

Data Label

With the data label you can display the data from your CSV file as it is. Remember to limit the number of characters in your labels for a clearer display.

Your map will look like this:

Areas Markers

You can change the colour code of each individual marker or group of markers to suit your data model.

The Data label for the areas markers works in the same way as for the point markers.
