基于WPF的DynamicDataDisplay曲线显示

一、DynamicDataDisplay下载和引用
1.新建项目，下载DynamicDataDisplay引用：
如下图：


二、前端开发：

        <Border Grid.Row="0" Grid.Column="2" BorderBrush="Purple" BorderThickness="1" Margin="2">
            <Grid>
                <Grid.RowDefinitions>
                    <RowDefinition Height="20"/>
                    <RowDefinition Height="*"/>
                </Grid.RowDefinitions>
                <CheckBox Grid.Row="0" Name="ShowMark" Content="ShowMark" IsChecked="True" Click="ShowMark_Click"/>
                <d3:ChartPlotter Grid.Row="1" Name="chartdemo">

                </d3:ChartPlotter>
            </Grid>
        </Border>

三、后端开发：
1、定义两条曲线：

        //曲线1
        private LineAndMarker<ElementMarkerPointsGraph> line1 = null;
        //曲线2
        private LineAndMarker<ElementMarkerPointsGraph> line2 = null;

2、设置曲线属性：

            //定义X轴数据
            var exds = new EnumerableDataSource<double>(Listx);
            exds.SetXMapping(p => p);
            //定义Y轴数据
            var eyds = new EnumerableDataSource<double>(Listy);
            eyds.SetYMapping(p => p);
            //定义鼠标点位显示值
            eyds.AddMapping(ShapeElementPointMarker.ToolTipTextProperty, p => string.Format("温度{0}", p));
            //定义数据
            IPointDataSource chartds1 = new CompositeDataSource(exds, eyds);

3、曲线赋值：

            line1 = chartdemo.AddLineGraph(chartds1,new Pen(Brushes.LimeGreen, 3),//曲线数据，曲线颜色，曲线宽度
                new CircleElementPointMarker { Size = 10, Fill = Brushes.Orange, Brush = Brushes.Red },//曲线标点的点大小和颜色
                new PenDescription("温度曲线"));//曲线的名称

4、控件刷新显示：

            chartdemo.Children.Add(new CursorCoordinateGraph());
            chartdemo.FitToView();

5、控制曲线是否显示标点：

            if (ShowMark.IsChecked == true)
            {
                line1.MarkerGraph.DataSource = chartds1;
            }
            else
            {
                line1.MarkerGraph.DataSource = null;
            }

6、清除某条曲线：

            if (line1 != null)
            {
                chartdemo.Children.Remove(line1.LineGraph);
            }

四、展示
