Looking at raw data and trying draw conclusions from it is very tedious. Visual representations such as charts and graphs overcome this problem. These visual representations, when powered by interactive features, are a piece of cake to understand. In this blog, I am going to walk you through the rich and highly interactive features of Syncfusion Flutter Charts, namely:
These features help users understand data in various ways. Users can experiment with their data’s presentation to answer questions about it with the best visuals. Let’s check out these rich interactive capabilities.
Tooltip
The tooltip is one of the Syncfusion Flutter Charts control’s most valuable features. On interacting with data points in a series, the specific data point values will be displayed in a pop-up called a tooltip. We can easily customize the tooltips to define additional chart point information, change their appearance, place images or custom widgets in them, and more. So, there’s almost no limit to the possibilities. Here are some of the key features of the tooltip:
- It can be enabled for all series in a chart.
- It can be activated on tap, double-tap, or long press.
- It can be positioned to always display at the top of the data point or at the pointer position.
- Its content can be formatted.
- Any widget can be used as a tooltip using Builder.
- It can be shown or hidden dynamically using public methods.
- Its appearance can be completely customized.
