折线图更新数据报错：RangeError: Invalid array length

[hongfa18]

在data数据递增更新时报错： RangeError: Invalid array length at eval (bezierCurveToPolyline.js?2db9:123) at Array.map () at getSegmentPointsDistance (bezierCurveToPolyline.js?2db9:122) at eval (bezierCurveToPolyline.js?2db9:233) at Array.forEach () at _loop (bezierCurveToPolyline.js?2db9:226) at calcUniformPointsByIteration (bezierCurveToPolyline.js?2db9:254) at abstractBezierCurveToPolyline (bezierCurveToPolyline.js?2db9:59) at bezierCurveToPolyline (bezierCurveToPolyline.js?2db9:294) at Graph.draw (graphs.js?b06d:591)

通过测试发现操作15条数据更新时报此错。
