Point Map
Point maps are a visualization tool designed to effectively represent quantitative data associated with specific geographic locations.
This visualization is particularly useful for datasets where data points are linked to precise coordinates.
Building Your Point Map
To create a point map, you must provide the following information:
* Location
Specify the geographic location of your data points (e.g., city, country, continent).
Once a field is dropped, select its appropriate geographic role from the dropdown menu.
OR
* Latitude & Longitude:
Provide the exact coordinates for each location.
Drag latitude (y) and longitude (x) fields to define map coordinates.
These fields must be of decimal data type and classified as measures.
Color by (Optional)
Use this field to categorize data points using color.
You can apply color based on numeric or categorical data.
Size (Optional)
Use this field to represent data points as bubbles of varying sizes. The field should be a measure, and you can use aggregations like COUNT or DISTINCT.
Tooltip (Optional)
Add additional fields to display detailed information when hovering over a data point. Multiple fields can be included.
Formatting Your Point Map
Title
This allows you to give a Title to the Line Chart. You just need to go to the Title section in the Format panel.
You can easily toggle it on or off. In the "Customize title" modal, you can:
Modify the title text, font size, and alignment, and even add a background color.
