Sharing An Axis

Notice this web site wraps every sample using the ContentPage class, but LiveCharts controls can be used inside any container, this sample also follows a Model-View-* pattern.

View model

using System;
using LiveChartsCore;
using LiveChartsCore.SkiaSharpView;

namespace ViewModelsSamples.Axes.Shared;

public class ViewModel
    public ViewModel()
        var values1 = new int[50];
        var values2 = new int[50];
        var r = new Random();
        var t = 0;
        var t2 = 0;

        for (var i = 0; i < 50; i++)
            t += r.Next(-90, 100);
            values1[i] = t;

            t2 += r.Next(-90, 100);
            values2[i] = t2;

        SeriesCollection1 = new ISeries[] { new LineSeries<int> { Values = values1 } };
        SeriesCollection2 = new ISeries[] { new ColumnSeries<int> { Values = values2 } };

        // sharing the same instance for both charts will keep the zooming and panning synced
        SharedXAxis = new Axis[] { new Axis() };

    public ISeries[] SeriesCollection1 { get; set; }
    public ISeries[] SeriesCollection2 { get; set; }
    public Axis[] SharedXAxis { get; set; }


<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns=""
            <RowDefinition Height="*"/>
            <RowDefinition Height="*"/>

          Notice we are binding the XAxes to the same instance, this way we are sharing both charts zooming and panning
          no matter in which chart you zoom, the other chart will share the view.

        <lvc:CartesianChart Grid.Row="0" Series="{Binding SeriesCollection1}" XAxes="{Binding SharedXAxis}" ZoomMode="X"></lvc:CartesianChart>
        <lvc:CartesianChart Grid.Row="1" Series="{Binding SeriesCollection2}" XAxes="{Binding SharedXAxis}" ZoomMode="X"></lvc:CartesianChart>
