flutter_radar_chart 0.0.2

Basic radar chart for Flutter. This chart is intended to work out of the box, adjusting itself to the given data. The design of the chart was inspired by the Python Graph Gallery.

Example

Usage

Basic usage of radar chart requires three pieces of data:

• ticks - Defines the numerical axis for the chart. Each tick generates an outline. Currently, each feature is plotted using the numerical range define by the ticks.
• features - Defines the numerical variables for each individual in the chart. There is no limit to the number of features.
• data - List of data points used to construct each individual in the chart. The number of data points must match the number of features. There is no limit to the number of individuals in the chart; however, multiple entities might cause the graph to become unreadable.

RadarChart.light(
    ticks: ticks,
    features: features,
    data: data,
),

A full example (as seen in the screenshots) can be found in example/lib/main.dart

Future Work Ideas

There's a few more areas of work that I'd love to get around to building. I will eventually move these items over to issues for better tracking.

• Option for round corners
• Animations on render
• Responsive design
• Legends
