If you have read Dashboard overview and Dashboard basic operations, read this section to learn about how to create a geo bubble map. If you need to edit the dataset or create a new dataset, see Create a dataset.
A bubble map uses a map profile as its background and attaches bubbles to the map to indicate data values. It intuitively shows the related data indexes and data ranges of a country or region. For example, a bubble map can be used to show the passenger flows of multiple tourist sites or the per capita incomes of multiple regions.
A bubble map consists of a geological region and a bubble size. The geological region is determined by the data dimension, such as a province. The bubble size is determined by the data measurement, such as a transportation cost or an order quantity.
Notice on creating a geo bubble map
You can set only one dimension for the geological region of a bubble map, and the dimension type must be of geological information, such as a region, a province, or a city. Set at least one bubble size and a maximum of five measurements.
The following uses the company_sales_record dataset as an example.
Scenario: Compare the order amount and average profits of multiple provinces.
- Log on to the Quick BI console.
- Click Datasets to enter the dataset management page.
- Select company_sales_record dataset, and click Create Dashboard.
- Click Geo bubble icon.
- On the Data tab, select a required dimension field and measurement fields.
In the dimension list, locate the province option and add it to the geological area. In the measurement list, locate the order_amt and order_number options and add them to the bubble size area in sequence, as shown in the following figure.
Note Make sure that the dimension type of the region and province fields have been switched from string to geological information.
