我有一个图表，我正在显示非常小的间隔时间数据（接近2分钟），当我使用图表centre处的拖动放大时，对服务器的调用获取缩放数据但是在x轴处，导航器（水平滚动）将放大的数据移动到它应该位于时间线中心的extreme left。
Say for example timeline has interval in seconds as below
0---30---60---90---120
and I zoom in at 30 to 90
The navigator or scroll axis should have stayed at 0---120 and the focus part should be 30---90
but In my case it changing the navigator to 30 to 120 and focus area moves to extreme left.
Note: with bigger time intervals it works fine
