modern_charts | Dart Package

A package for creating simple yet modern looking charts.

Five chart types

Bar
Gauge
Line
Pie
Radar

Canvas + DOM

modern_charts combines Canvas and DOM to achieve the best performance and experience.

Canvas is used to render chart contents (axes, grids, and series)
DOM is used to create legends and tooltips

DataTable

Data are passed to a chart via a DataTable object. By using DataTable, you can flexibly modify the data even after the chart has been rendered.

Animations

Animations are supported for different types of data modifications:

New data table
Changes to data table values
Insertion and removal of rows (categories)
Insertion and removal of columns (series)
Series visibility toggle

Responsive

Charts automatically resize when the browser is resized.

Interactive

Shows tooltips on hover/tap
The visibility of a series is toggled when you click the corresponding legend item

Modular

Each chart type has its own class, so your final production code only contains the code of the chart types you use.
