model-view-controller - System.Web.UI.DataVisualization.Charting を使用してラベルを正しく配置する方法

Question

System.Web.UI.DataVisualization.Charting で生成されたグラフがあります。以下はコードです

public ActionResult MBRRChart()
    {
        //Area for generating chart type Range bar
        List<dummyGraph> objGraphList = new List<dummyGraph>();
        dummyGraph objDummyGraph = new dummyGraph();
        objDummyGraph.TKFEType = "Underwriter";
        objDummyGraph.min = 1;
        objDummyGraph.max = 8;
        objDummyGraph.Median = "1";
        objGraphList.Add(objDummyGraph);

        objDummyGraph = new dummyGraph();
        objDummyGraph.TKFEType = "Construction";
        objDummyGraph.min = 2;
        objDummyGraph.max = 5;
        objDummyGraph.Median = "2";
        objGraphList.Add(objDummyGraph);

        objDummyGraph = new dummyGraph();
        objDummyGraph.TKFEType = "Design";
        objDummyGraph.min = 3;
        objDummyGraph.max = 6;
        objDummyGraph.Median = "3";
        objGraphList.Add(objDummyGraph);

        objDummyGraph = new dummyGraph();
        objDummyGraph.TKFEType = "Partner";
        objDummyGraph.min = 4;
        objDummyGraph.max = 6;
        objDummyGraph.Median = "3";
        objGraphList.Add(objDummyGraph);

        objDummyGraph = new dummyGraph();
        objDummyGraph.TKFEType = "Construction";
        objDummyGraph.min = 2;
        objDummyGraph.max = 5;
        objDummyGraph.Median = "2";
        objGraphList.Add(objDummyGraph);

        objDummyGraph = new dummyGraph();
        objDummyGraph.TKFEType = "Design";
        objDummyGraph.min = 3;
        objDummyGraph.max = 6;
        objDummyGraph.Median = "3";
        objGraphList.Add(objDummyGraph);

        objDummyGraph = new dummyGraph();
        objDummyGraph.TKFEType = "Partner";
        objDummyGraph.min = 4;
        objDummyGraph.max = 6;
        objDummyGraph.Median = "3";
        objGraphList.Add(objDummyGraph);

        objDummyGraph = new dummyGraph();
        objDummyGraph.TKFEType = "Construction";
        objDummyGraph.min = 2;
        objDummyGraph.max = 5;
        objDummyGraph.Median = "2";
        objGraphList.Add(objDummyGraph);

        objDummyGraph = new dummyGraph();
        objDummyGraph.TKFEType = "Design";
        objDummyGraph.min = 3;
        objDummyGraph.max = 6;
        objDummyGraph.Median = "3";
        objGraphList.Add(objDummyGraph);

        objDummyGraph = new dummyGraph();
        objDummyGraph.TKFEType = "Partner";
        objDummyGraph.min = 4;
        objDummyGraph.max = 6;
        objDummyGraph.Median = "3";
        objGraphList.Add(objDummyGraph);

        objDummyGraph = new dummyGraph();
        objDummyGraph.TKFEType = "Construction";
        objDummyGraph.min = 2;
        objDummyGraph.max = 5;
        objDummyGraph.Median = "2";
        objGraphList.Add(objDummyGraph);

        objDummyGraph = new dummyGraph();
        objDummyGraph.TKFEType = "Design";
        objDummyGraph.min = 3;
        objDummyGraph.max = 6;
        objDummyGraph.Median = "3";
        objGraphList.Add(objDummyGraph);

        objDummyGraph = new dummyGraph();
        objDummyGraph.TKFEType = "Partner";
        objDummyGraph.min = 4;
        objDummyGraph.max = 6;
        objDummyGraph.Median = "3";
        objGraphList.Add(objDummyGraph);

        System.Web.UI.DataVisualization.Charting.Chart chart1 = new System.Web.UI.DataVisualization.Charting.Chart();
        System.Web.UI.DataVisualization.Charting.ChartArea chartArea1 = new System.Web.UI.DataVisualization.Charting.ChartArea();
        System.Web.UI.DataVisualization.Charting.Legend legend1 = new System.Web.UI.DataVisualization.Charting.Legend();
        System.Web.UI.DataVisualization.Charting.Series seriesInstance;

        chart1.Titles.Add("Market Based Rate Range");//Add chart title 

        //chart series initialization
        seriesInstance = new System.Web.UI.DataVisualization.Charting.Series("xAxis");
        seriesInstance.ChartType = SeriesChartType.RangeBar;//Set chart type here
        seriesInstance.Color = Color.SkyBlue;
        seriesInstance.YValuesPerPoint = 2;
        seriesInstance.SmartLabelStyle.Enabled = true;
        seriesInstance.IsValueShownAsLabel = true;
        //END

        chart1.Series.Add(seriesInstance);

        //Bind values to chart
        chart1.DataSource = objGraphList;
        chart1.Series[0].XValueMember = "TKFEType";
        chart1.Series[0].YValueMembers = "min, max";
        chart1.Series[0].Label = "#VALY <-> #VALY2";

        chart1.DataBind();
        //END

        chart1.ChartAreas.Add(chartArea1);
        chartArea1 = chart1.ChartAreas[0];

        //Used to hide Grid lines
        chartArea1.AxisX.MajorGrid.Enabled = false;
        chartArea1.AxisX.MinorGrid.Enabled = false;
        chartArea1.AxisY.MajorGrid.Enabled = false;
        chartArea1.AxisY.MinorGrid.Enabled = false;
        //END

        //Used to hide the x axis values
        chartArea1.AxisY.Enabled = AxisEnabled.False;
        //END

        //END

        //Area for returning created chart as image file
        using (MemoryStream ms = new MemoryStream())
        {
            chart1.SaveImage(ms, ChartImageFormat.Png);
            return File(ms.ToArray(), "image/png");
        }
        //END
    }
    //END

上記のコードを実行すると、チャートは次の画像のようになります

その画像では、Yaxis ラベルとバーが適切に整列していないことがわかります (同じ行で)。

なぜそうなのか

Answer 1

以前のコメントで述べたように、場合によっては範囲バーが狭すぎてラベルを含めることができないため、チャートはそれを外に出します. と でいくつかのプロパティを試しましたが、どれも効果がないようですSmartLabelStyle。CustomProperties

Y 軸に沿った垂直方向の配置に関して、私の提案は重複を持たないことです。複数作成しList<DummyGraph>、それぞれを独自のチャートにバインドしますSeries。こうすることで、重複がなくなり、すべてが整列して見栄えが良くなります。

ここ：

    protected void Page_Load(object sender, EventArgs e)
    {
        //Just creating some random data
        Random r = new Random();
        DummyGraphList data1 = new DummyGraphList(r);
        DummyGraphList data2 = new DummyGraphList(r);

        //Bind each list to its own series
        Chart1.Series[0].Points.DataBind(data1, "TKFType", "Min,Max", null);
        Chart1.Series[1].Points.DataBind(data2, "TKFType", "Min,Max", null);
    }

結果：
