SpreadJS 支持折线图、堆积折线图、百分比堆积折线图、数据点折线图、数据点堆积折线图、数据点百分比堆积折线图。通过 GC.Spread.Sheets.Charts.ChartType.line 来指定chartType为折线图。
您可以将折线图添加到Spread，并使用图表API更改其样式（如平滑线条）
折线图也可以是堆积折线图、百分比堆积折线图、数据点折线图、数据点堆积折线图、数据点百分比堆积折线图。使用 GC.Spread.Sheets.Charts.ChartType.lineStacked , GC.Spread.Sheets.Charts.ChartType.lineStacked100, GC.Spread.Sheets.Charts.ChartType.lineMarkers, GC.Spread.Sheets.Charts.ChartType.lineMarkersStacked, GC.Spread.Sheets.Charts.ChartType.lineMarkersStacked100 来指定这两种柱形图
你可以自定制图表中系列标记的颜色，形状以及标记边框：
折线图和数据点折线图： 折线图在显示时可以带有指示单个数据值的标记，也可以不带标记，可显示一段时间或均匀分布的类别的趋势，特别是你有多个数据点，并且这些数据点的出现顺序非常重要时。当有许多类别或值的大小接近时，请使用无数据点折线图。
堆积折线图和数据点堆积折线图： 堆积折线图显示时可带有标记以指示各个数据值，也可以不带标记，可显示每个值所占大小随着时间或均匀分布的类别而变化的趋势。
百分比堆积折线图和数据点百分比堆积折线图： 百分比堆积折线图显示时可带有标记以指示各个数据值，也可以不带标记，可显示每个值所占的百分比随时间或均匀分布的类别而变化的趋势。如果有许多类别或值大小接近，请使用无数据点百分比堆积折线图。
