WPF绘制图表-LiveCharts

LiveCharts是一款非常好用的WPF图表绘制类库，相比其他同类类库，LiveCharts的UI风格样式更加多样更加美观。

准备工作：安装以下两个类库：

1、甘特图

前台View代码

 1 <lvc:CartesianChart Grid.Row="2" Zoom="None" Margin="0,40">
 2     <lvc:CartesianChart.AxisX>

 6                   MinValue="{Binding Path=From, Mode=TwoWay}" 
 7                   MaxValue="{Binding Path=To, Mode=TwoWay}">
 8             <!--Separator-坐标平面分割线 StrokeDashArray-分割线虚线间隔-->
 9             <lvc:Axis.Separator>
10                 <lvc:Separator Stroke="#33ffffff" StrokeDashArray="10"/>
11             </lvc:Axis.Separator>

20             </lvc:Axis.Separator>
21         </lvc:Axis>
22     </lvc:CartesianChart.AxisY>
23     <!--Series-数据序列-->
24     <lvc:CartesianChart.Series>
25         <!--RowSeries-数据序列按行显示 LabelPosition-数据标签位置 DataLabels-是否显示数据标签 Values-数据序列值-->
26         <lvc:RowSeries Style="{StaticResource FontRowSeries}"
