在Open XML中更新图表属性

Question

我最近尝试使用Open XML和C＃在Excel中创建条形图。

下面是帮助我在excel中创建条形图的脚本部分。

 // Add a new drawing to the worksheet.
DrawingsPart drawingsPart = worksheetPart.AddNewPart<DrawingsPart>();
worksheetPart.Worksheet.Append(new DocumentFormat.OpenXml.Spreadsheet.Drawing() { Id = worksheetPart.GetIdOfPart(drawingsPart) });
worksheetPart.Worksheet.Save();

// Add a new chart and set the chart language to English-US.
ChartPart chartPart = drawingsPart.AddNewPart<ChartPart>();
chartPart.ChartSpace = new ChartSpace();
chartPart.ChartSpace.Append(new EditingLanguage() { Val = new StringValue("en-US") });
Drawing.Charts.Chart chart = chartPart.ChartSpace.AppendChild<Drawing.Charts.Chart>(new Drawing.Charts.Chart());
addChartTitle(chart, chartTitleText);

// Create a new clustered column chart.
PlotArea plotArea = chart.AppendChild<PlotArea>(new PlotArea());
Layout layout = plotArea.AppendChild<Layout>(new Layout());
addBarchart(plotArea);
addCategoryAxis(plotArea);

// Add the Value Axis.
ValueAxis valAx = plotArea.AppendChild<ValueAxis>(new ValueAxis(new AxisId() { Val = new UInt32Value(48672768u) },
    new Scaling(new Orientation() { Val = new EnumValue<DocumentFormat.OpenXml.Drawing.Charts.OrientationValues>(DocumentFormat.OpenXml.Drawing.Charts.OrientationValues.MinMax) }),
    new AxisPosition() { Val = new EnumValue<AxisPositionValues>(AxisPositionValues.Left) }, new MajorGridlines(), new DocumentFormat.OpenXml.Drawing.Charts.NumberingFormat()
    { FormatCode = new StringValue("General"), SourceLinked = new BooleanValue(true) }, new TickLabelPosition() { Val = new EnumValue<TickLabelPositionValues> (TickLabelPositionValues.NextTo) },
    new CrossingAxis() { Val = new UInt32Value(48650112U) }, new Crosses() { Val = new EnumValue<CrossesValues>(CrossesValues.AutoZero) }, new CrossBetween() { Val = new EnumValue<CrossBetweenValues>(CrossBetweenValues.Between) }));

但不幸的是，当我尝试编辑酒吧的颜色时，我无法成功。请帮我创建一个图表并使用Open XML和C＃更新图表属性。
