基本应用 | 功能例子 | SpreadJS JavaScript 学习指南

要使用图表功能，请将SpreadJS Chart JS文件链接添加到文档的head部分您可以使用sheet.charts.add方法创建图表，如下所示：另外，您还可以指定图表的多个数据源：当设置的数据源等于表结构引用时，图表将自动更新系列区域你可以通过 sheet.charts.get 方法来获取一个图表的实例，通过 sheet.charts.remove 方法来移除sheet上的一个图表，也可以通过 sheet.charts.clear 方法来清空sheet上的所有chart。一个图表是由许多子元素构成的，你可以通过chart的API来自定义它们: Chart Title: chart的标题你可以通过如下方式来获取或者设置一个chart的标题 (标题可设置的属性包括:text, back color, fore color, font and fontSize) Series: chart的系列你可以从chart的series collection中获取、添加或者移除一个系列, 也可以自定义一个系列的属性 (系列可设置的属性包括：name, border width, border color, yValue, xValue and fill color)，具体请参照如下的示例代码： Data Labels: 数据标签，用于标识数据点的详情你可以通过如下方式来获取或者设置一个chart的数据标签的样式 showValue showSeriesName showCategoryName showPercentage separator position format color transparency backColor backColorTransparency borderColor borderWidth borderColorTransparency SpreadJS 提供了28种chart类型，你可以获取当前chart的类型或者将它改为另一个不同的类型。 SpreadJS 图表支持对于空值单元格或#N/A值单元格的控制处理，如下。 gaps: 空值将被过滤 zero: 空值将被当做0值处理 connected: 空值将被过滤并且线形将跳过空值区域 SpreadJS 图表支持对于隐藏行列的控制处理，如下。 SpreadJS 支持导入时保留或者忽略不受支持的图标类型
