Question

enter image description here 我正在尝试向图表添加一个额外的数据系列，这显示了CPU阈值，我可以获取范围并创建超出阈值的图表，但我不知道如何添加图表的阈值。我需要创建另一个图表对象吗？我可以使用现有的，只需添加新的范围吗？

Threshold values

你是如何创建图表的？ - 见下面的代码。此图表是否已在Excel文件中创建，并且您要修改Excel文件中的图表？是的，图表已经在Excel文件中了。

Excel.ChartObjects sCPUChart; Excel.ChartObject sCPUChartObjects;

        sCPUChart = sDBSheet.ChartObjects(Type.Missing);
        sCPUChartObjects = sCPUChart.Add(49, 15, 360, 215);

        Excel.Chart sChartCPU;

        sChartCPU = sCPUChartObjects.Chart;
        sChartCPU.SetSourceData(cpuChartRange, Missing.Value);
        sChartCPU.ChartWizard(Source: cpuChartRange, Gallery: Excel.XlChartType.xlLine, Format: 2, HasLegend: true);
        sChartCPU.Location(Excel.XlChartLocation.xlLocationAsObject, sDBSheet.Name);

        //CPU Chart Axis
        Excel.Axis xSChartCPUAxis;
        xSChartCPUAxis = sChartCPU.Axes(Excel.XlAxisType.xlCategory, Excel.XlAxisGroup.xlPrimary);


        Excel.Axis ySChartCPUAxis;
        ySChartCPUAxis = syChartCPU.Axes(Excel.XlAxisType.xlValue, Excel.XlAxisGroup.xlPrimary);
        ySChartCPUAxis.HasMajorGridlines = true;
        ySChartCPUAxis.MaximumScaleIsAuto = true;

        //Set Summary CPU Series
        Excel.Series sCPUSeries = sChartCPU.SeriesCollection(1);
        sCPUSeries.Name = "CPU";


//-------
// this is where I am having my issue
//I don't know how to add the threshold line to the graph with the existing graph being displayed

        //sChartCPU.set_HasAxis(Excel.XlAxisType.xlCategory, Excel.XlAxisGroup.xlSecondary, true);
        //summaryChartCPU.SetSourceData(summaryMemThreshold, Type.Missing); -- things break
        //-------
I have now done the following:


   Excel.SeriesCollection threshold = sChartCPU.sseriesCollection();
   Excel.Series line = threshold.NewSeries();
   line.Formula = "=SERIES(Summ!$D$54,Summ!$C$55:$C$56,Summ!$D$55:$D$56)";
   line.ChartType = Excel.XlChartType.xLScatterLinesNoMarkers;


when the threshold line is created I have the following

with new series

我在单元格D54中的值 - 阈值

我不知道如何删除图表中显示的2个附加轴如果我注释掉line.ChartType，那么轴是正确的但我只得到一个阈值数据点？我不明白为什么。

Answer 1

var series = (SeriesCollection) yourChart.SeriesCollection();
var line = series.NewSeries();

line.Name = "CPU Threshhold";
//line.Values = ...;
//line.XValues = ...;

//formatting

这是我找到的关于OP移除辅助轴问题的解决方案：

ALTER PROCEDURE files_uploadAll
    @document_id INT OUTPUT,
    @files NVARCHAR(MAX)

/*
