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
