Aspose.Words是一款先进的文档处理控件，在不使用Microsoft Words的情况下，它可以使用户在各个应用程序中执行各种文档处理任务，其中包括文档的生成、修改、渲染、打印，文档格式转换和邮件合并等文档处理。此外，Aspose.Words支持DOC，OOXML，RTF，HTML，OpenDocument, PDF, XPS, EPUB和其他格式。
使用ChartDataLabel你可以规定单个图表系列的数据标签的格式，像显现/隐藏图例、种类名字、SeriesName、值等等。
C# ChartDataLabelCollection dataLabelCollection = series0.DataLabels; // Add data label to the first and second point of the first series. ChartDataLabel chartDataLabel00 = dataLabelCollection.Add(0); ChartDataLabel chartDataLabel01 = dataLabelCollection.Add(1); // Set properties. chartDataLabel00.ShowLegendKey = true; // By default, when you add data labels to the data points in a pie chart, leader lines are displayed for data labels that are // positioned far outside the end of data points. Leader lines create a visual connection between a data label and its // corresponding data point. chartDataLabel00.ShowLeaderLines = true; chartDataLabel00.ShowCategoryName = false; chartDataLabel00.ShowPercentage = false; chartDataLabel00.ShowSeriesName = true; chartDataLabel00.ShowValue = true; chartDataLabel00.Separator = "/"; chartDataLabel01.ShowValue = true;
VB Dim dataLabelCollection As ChartDataLabelCollection = series0.DataLabels ' Add data label to the first and second point of the first series. Dim chartDataLabel00 As ChartDataLabel = dataLabelCollection.Add(0) Dim chartDataLabel01 As ChartDataLabel = dataLabelCollection.Add(1) ' Set properties. chartDataLabel00.ShowLegendKey = True ' By default, when you add data labels to the data points in a pie chart, leader lines are displayed for data labels that are ' positioned far outside the end of data points. Leader lines create a visual connection between a data label and its ' corresponding data point. chartDataLabel00.ShowLeaderLines = True chartDataLabel00.ShowCategoryName = False chartDataLabel00.ShowPercentage = False chartDataLabel00.ShowSeriesName = True chartDataLabel00.ShowValue = True chartDataLabel00.Separator = "/" chartDataLabel01.ShowValue = True
结果如下：
