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
