我有一个带双窗格的Highstock图表（顶部和底部）。我知道范围选择器将从xAxis极值读取以设置起始日期。
每次我添加一个系列，无论是顶部还是底部，我都必须调用：chart.xAxis [0] .setExtremes（）;为了让范围选择器能够刷新＆＃34;从和到日期（如有必要）。
现在，当我必须为导出模块执行相同的步骤时，问题就出现了。在将其传递到本地导出服务器之前，如何将极限配置到我的选项数组中？目前，似乎当我执行导出时，From / To Date偶尔会与我使用xAxis.min和xAxis.max设置的不同。
感谢任何帮助/建议。谢谢。
UPDATE /编辑：
我目前正在使用以下选项生成我的图表。图表的xAx是根据xAxis＆＃39;显示的。最小值和最大值1315756800000（2011年第12季度）和1338134400000（2012年第28季度）。但是，如果我要复制以下代码并在http://export.highcharts.com/上导出，则日期将于2011年11月11日至2012年5月27日。任何想法为什么？
