使用 JavaScript 通过 C++ 调整图表的数据标签形状以适应文本

Excel应用程序提供了调整形状以适应文本选项，用于图表的数据标签，以增大形状的尺寸，以使文本适应其中。

如何在Microsoft Excel中调整图表数据标签的形状以适应文本

此选项可通过在 Excel 界面中选择图表上的任意数据标签，右键点击并选择 格式数据标签 菜单，然后在 大小与属性 标签下展开 对齐方式，以显示相关属性，包括 调整形状以适应文本 选项。

如何使用 Aspose.Cells for JavaScript 通过 C++ 调整图表的数据标签形状以适应文本

为了模仿Excel的调整数据标签形状以适应文本的功能，Aspose.Cells API已暴露布尔类型的DataLabels.isResizeShapeToFitText()属性。以下代码展示了DataLabels.isResizeShapeToFitText()属性的简单使用场景。
