Tencent Cloud BI product includes map charts such as bubble maps, color maps, and point maps, mainly used to show data size and distribution range of objects via maps, with GIS map support.
Note: When configuring map charts, you must first switch the field type of geographic information fields to geographic fields in the edit data table page. Among them, provinces/municipalities/autonomous regions/cities do not need suffixes like province, municipality, autonomous region, or city. The administrative division for districts/counties must correspond to complete zone names.
Bubble Map
Bubble maps are mainly used to compare data size and differences between items through horizontal display. As shown in the figure below, it displays the number of cities in each province.
Query Condition Settings
Dimensionality & metric count requirement: dimension=1, metric=1. Conditional filtering can be performed by dragging and dropping time, character, or numeric value fields in the condition section. The immediate analysis button triggers the chart's data update display, and the maximum display of XX results (0-10000) can be set on the right.
