如何创build一个使用表格作为数据源的折线图？

OpenXML SDK生产力工具无疑是非常有用的，但是在开放的XML中创build一个折线图，其中包含六个单元格的表格会生成8000条生成的代码行。

我找不到任何有关如何做这个看似简单的事情的文档：

1. 创build一个图表
2. 使用公式如x1=Table1[Date], y1=Table1[Temp1], x2=Table1[Date], y2=Table1[Temp2]

我已经重新考虑了OpenXMLSDK工具生成的很多代码，试图制作一个简单的方法：根据需要传递包含数据的表/单元格的许多公式/系列。

它的工作， 但仍然有很多生成的代码，它仍然是非常丑陋的，调查和一项工作正在进行中 。 如果您改进了，请随时发布您的更改。

样本用法：

1. 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build一个具有“时间”，“温度1”和“温度2”列的新表。 不要插入图表。

2. 将下面的代码粘贴到“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，无法粘贴。 我添加了一个链接： http : //pastebin.com/63XKknxx
