原创不易，打字不易，截图不易，多多点赞，送人玫瑰，留有余香，财务自由明日实现 

1、引用LiveCharts

2、创建LiveChartViewModel

using GalaSoft.MvvmLight;
using LiveCharts.Wpf;
using LiveCharts;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using GalaSoft.MvvmLight.Command;
using West.StoreMgr.Service;namespace West.StoreMgr.ViewModel
{/// <summary>/// 柱状图viewmodel/// </summary>public class LiveChartViewModel : ViewModelBase{//物资库存柱状private IChartValues goodsChartValues = new ChartValues<double>();public IChartValues GoodsChartValues{get { return goodsChartValues; }set { goodsChartValues = value; RaisePropertyChanged(); }}private List<string> goodsLabes = new List<string>();/// <summary>/// 物资标签/// </summary>public List<string> GoodsLabes{get { return goodsLabes; }set { goodsLabes = value; RaisePropertyChanged(); }}//物资入库流水折线public SeriesCollection GoodsInStoreSeries { get; set; } = new SeriesCollection();public AxesCollection GoodsInStoreAxis { get; set; } = new AxesCollection();//物资出库流水折线public SeriesCollection GoodsOutStoreSeries { get; set; } = new SeriesCollection();public AxesCollection GoodsOutStoreAxis { get; set; } = new AxesCollection();//客户出库饼图public SeriesCollection CustomerPieSeries { get; set; } = new SeriesCollection();/// <summary>/// 加载命令/// </summary>public RelayCommand LoadCommand{get{return new RelayCommand(() =>{ GoodsChartValues.Clear();GoodsLabes.Clear();var goodsList = new GoodsService().Select();var instoreList = new InStoreService().Select();var outstoreList = new OutStoreService().Select();var customers = new CustomerService().Select();goodsList.ForEach(goods =>{//物资库存柱状GoodsChartValues.Add(goods.Quant);GoodsLabes.Add(goods.Name);//物资入库流水折线var instores = instoreList.FindAll(item => item.GoodsSerial == goods.Serial);var inserise = new LineSeries() { Title = goods.Name, Values = new ChartValues<double>() };instores.ForEach(item =>{inserise.Values.Add(item.Number);});GoodsInStoreSeries.Add(inserise);//物资出库流水折线var outstores = outstoreList.FindAll(item => item.GoodsSerial == goods.Serial);var outserise = new LineSeries() { Title = goods.Name, Values = new ChartValues<double>() };outstores.ForEach(item =>{outserise.Values.Add(item.Number);});GoodsOutStoreSeries.Add(outserise);});CustomerPieSeries.Clear();customers.ForEach(item =>{var list = outstoreList.FindAll(outstore => outstore.CustomerId == item.Id);var sum = list.Sum(t => t.Number);var pieSeries = new PieSeries{Title = item.Name,Values = new ChartValues<double>() { sum }};CustomerPieSeries.Add(pieSeries);}); });}}}
}

3、创建LiveChartView用户控件

<UserControl x:Class="West.StoreMgr.View.LiveChartView"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:local="clr-namespace:West.StoreMgr.View"xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity" xmlns:wpf="clr-namespace:LiveCharts.Wpf;assembly=LiveCharts.Wpf"mc:Ignorable="d" DataContext="{Binding Source={StaticResource Locator},Path=LiveChart}"d:DesignHeight="450" d:DesignWidth="800"><i:Interaction.Triggers><i:EventTrigger EventName="Loaded"><i:InvokeCommandAction Command="{Binding LoadCommand}"/></i:EventTrigger></i:Interaction.Triggers><Grid><Grid.RowDefinitions><RowDefinition Height="50"/><RowDefinition Height="auto"/><RowDefinition/></Grid.RowDefinitions><!--标题--><StackPanel Background="#EDF0F6" Orientation="Horizontal"><TextBlock Margin="10 0 0 0" Text="&#xf015;" FontSize="20" FontFamily="/Fonts/#FontAwesome" HorizontalAlignment="Left" VerticalAlignment="Center" Foreground="#797672"/><TextBlock Margin="10 0 0 0" Text="首页 > 报表统计" FontSize="20" FontFamily="/Fonts/#FontAwesome" HorizontalAlignment="Left" VerticalAlignment="Center" Foreground="#797672"/></StackPanel><!--增加--><Grid Grid.Row="1" Margin="10"></Grid><!--报表--><Grid Grid.Row="2" Margin="10 0 10 10" ><Grid.ColumnDefinitions><ColumnDefinition/><ColumnDefinition/></Grid.ColumnDefinitions><Grid.RowDefinitions><RowDefinition/><RowDefinition/></Grid.RowDefinitions><!--物资库存柱状图--><TextBlock Text="物资库存柱状图" Grid.Row="0" Grid.Column="0" Margin="150 -20 0 0" FontSize="15" FontFamily="微软雅黑" ></TextBlock><Border Grid.Row="0" Grid.Column="0" BorderBrush="BurlyWood"  BorderThickness="0.5"><wpf:CartesianChart  Margin="10"><wpf:CartesianChart.Series><wpf:ColumnSeries Values="{Binding GoodsChartValues}"/></wpf:CartesianChart.Series><wpf:CartesianChart.AxisX><wpf:Axis ShowLabels="True" Labels="{Binding GoodsLabes}"><wpf:Axis.Separator><wpf:Separator Step="1" IsEnabled="False"/></wpf:Axis.Separator></wpf:Axis></wpf:CartesianChart.AxisX></wpf:CartesianChart></Border><!--客户出库统计饼图--><TextBlock Text="客户出库统计饼图" Grid.Row="0" Grid.Column="1" Margin="150 -20 0 0" FontSize="15" FontFamily="微软雅黑"></TextBlock><Border Grid.Row="0" Grid.Column="1"  BorderBrush="BurlyWood"  BorderThickness="0.5"><wpf:PieChart LegendLocation="Right" Hoverable="True" InnerRadius="30" Series="{Binding CustomerPieSeries}"><wpf:PieChart.ChartLegend><wpf:DefaultLegend Foreground="Green"/></wpf:PieChart.ChartLegend></wpf:PieChart> </Border> <!--物资入库流水记录--><TextBlock  Text="物资入库流水记录" Grid.Row="1" Grid.Column="0"  Margin="150 0 0 0" FontSize="15" FontFamily="微软雅黑"></TextBlock><Border Grid.Row="1" Grid.Column="0" BorderBrush="BurlyWood"  BorderThickness="0.5"> <wpf:CartesianChart  Series="{Binding GoodsInStoreSeries}" AxisX="{Binding GoodsInStoreAxis}"/></Border><!--物资出库流水记录--><TextBlock Text="物资出库流水记录" Grid.Row="1" Grid.Column="1" Margin="150 0 0 0" FontSize="15" FontFamily="微软雅黑" ></TextBlock><Border Grid.Row="1" Grid.Column="1"  BorderBrush="BurlyWood"  BorderThickness="0.5"> <wpf:CartesianChart Margin="10" Series="{Binding GoodsOutStoreSeries}" AxisX="{Binding GoodsOutStoreAxis}"/></Border></Grid></Grid>
</UserControl>
