Flutter HiLo Chart | High-Performance Chart

Overview

The Flutter HiLo Chart is similar to OHLC, but shows the high and low values of the stock over the given period of time. You can create beautiful, animated, real-time and high-performance hilo chart that also supports the interactive features such as zooming and panning, trackball, crosshair, tooltip and selection.

Key features

Multi series

Allows you to plot multiple series in a single chart to compare different data sets. Enabling legend and tooltip gives more information about the individual series.

Data label

Data labels display information about data points. Add a template to display data labels with any custom widgets for more informative data labels. You can rotate a data label by its given angle.

Customization

Customize the color, thickness, and dash array of the Flutter HiLo Chart using built-in APIs.

Code example

Easily get started with the Flutter High Low (HiLo) Chart using a few simple lines of DART code example as demonstrated below,

dart
import 'package:flutter/material.dart';
import 'package:syncfusion_flutter_charts/charts.dart';

@override
    Widget build(BuildContext context) {
        return Scaffold(
            body: Center(
                child: Container(
                    child: SfCartesianChart(
                        primaryXAxis: DateTimeAxis(),
                        series: <ChartSeries>[
                            // Renders bar chart
                            HiloSeries<SalesData, DateTime>(
                                dataSource: chartData,
                                xValueMapper: (SalesData sales, _) => sales.year,
                                  lowValueMapper: (Sample sales, _) => sales.low,
              highValueMapper: (Sample sales, _) => sales.high
                            )
                        ]
                    )
                )   
            )
        );
    }
