SpeadJS允许用户控制是否在图表中显示隐藏的行或列的数据。 ignoreHidden 函数设置为true时,不会在图表中显示隐藏的行或列的数据。 通过SpreadJS设计器,也可以通过选中“忽略隐藏的行和列”复选框来实现相同的目的。
A 如果满足以下条件,则认为行或列是隐藏的:
示例 -下图描绘了显示不同公司智能手机的每日销售记录的图表。 您可能会注意到,表单中隐藏了第三行以及C和D列。 可见数据是2家公司(Apple和LG)的4个日期的数据,而图表显示了3家公司(同样是三星)的6个日期的数据。 要显示图表中隐藏行和列的数据,请将 ignoreHidden 函数的值设置为true,将显示您的图表,如以下截图所示。
请参考以下示例代码,以显示图表中隐藏的行或列的数据。
// 创建数组

// 添加图表
var chart = activeSheet.charts.add('LineChart', GC.Spread.Sheets.Charts.ChartType.line, 2, 85, 400, 400, 'A1:G4');
// 设置图表标题
chart.title({ text: "Sales Record" });
// 将ignoreHidden方法设置为false,以便在图表中显示隐藏的行和列
chart.ignoreHidden(false);
