Question

然而，OpenXML SDK Productivity工具无疑非常有用在开放XML中创建一个折线图，它引用一个包含六个单元格的表，产生8000行代码。

我找不到任何关于如何做这件看似简单的事情的文件：

创建图表
使用类似x1=Table1[Date], y1=Table1[Temp1], x2=Table1[Date], y2=Table1[Temp2]

我已经重新考虑了OpenXMLSDK工具生成的大量代码，试图制作一个简单的方法：将它传递给许多公式/系列，引用包含您想要的数据的表格/单元格。 / p>

它有效，然而仍然有很多生成的代码，它仍然非常丑陋，令人沮丧，正在进行中。如果您改进它，请随时发布您的更改。

样本用法：

使用OpenXML SDK生产力工具从excel文件生成代码。在名为Table1的文件中创建一个新表，其中包含“Time”，“Temp 1”和“Temp 2”列。不要插入图表。

将以下代码粘贴到“CreateParts”方法的末尾：

using C = DocumentFormat.OpenXml.Drawing.Charts;
C.Marker marker3 = OpenXMLUtils.CreateMarker(C.MarkerStyleValues.Circle, 5, A.SchemeColorValues.Accent1);
C.Marker marker2 = OpenXMLUtils.CreateMarker(C.MarkerStyleValues.Circle, 5, A.SchemeColorValues.Accent2);
C.ScatterChartSeries scatterChartSeries1 = OpenXMLUtils.CreateSeries(0U, "Table1[Time]", "Table1[Temp 1]", marker3);
C.ScatterChartSeries scatterChartSeries2 = OpenXMLUtils.CreateSeries(1U, "Table1[Time]", "Table1[Temp 2]", marker2);

OpenXMLUtils.CreateChartSheet(workbookPart1, 2U, "Chart Sheet", scatterChartSeries1, scatterChartSeries2);

代码太长，无法在此处粘贴。我添加了一个链接： http://pastebin.com/63XKknxx
