Tooltip Chart

The Tooltip Chart displays metrics related to the selected layer in your mouse-over tooltip. Based on the layers present on the map, Studio will provide several charts types to select from.

Follow these steps to create a tooltip chart:

1. Click the Show Charts button on the top-right of the window.

2. Click Add Chart > Tooltip Chart.

You may select from a variety of charts based on the layers present in your visualization. To configure the chart, click Chart Settings.

Flow Layer Charts

The Flow Layer currently supports the following Tooltip Chart types: "Top Origins" and "Top Destinations." These charts describe the top origins and destinations for any given cluster on the map.

The charts will update to the viewport when zooming to show the clustered locations for the current zoom level. The automatic clustering can be disabled in the layer configuration panel.

Using the Tooltip Chart with the Flow Layer, you can display chart metrics in the mouse-over tooltip. This allows users to interactively explore the top origins and destinations for any given point on the map.

Category Breakdown Chart

The Category Breakdown chart allows you to configure a visual ranking of the top categories in a given area.

By default, the Category Breakdown chart ranks all categories that exist in your current viewport. Alternatively, you can configure the chart to appear in a mouse-over tooltip, showing the top categories for a specific location on the map.

The Category Breakdown Chart requires your layer to reference a dataset containing a "struct" column with JSON objects mapping keys to numeric values. Learn more about formatting a struct object for use in Studio.

Time Series Chart

The Time Series chart displays a series of data points ordered by time. This chart requires a layer with a time column.

By default, the Time Series chart displays information regarding all data points on the map. Hover over a data point on the map to view its data in the Time Series chart window.

Alternatively, you can configure the chart to appear in a mouse-over tooltip, showing a Time Series chart for a specific data point on the map.
