live preview issue in chart builder

build£º
2.6.0.v20100322

steps to reproduce:
1. new a chart binding to data set [customers]
2. check the live preview in chart builder: 124 as largest x value
3. add a filter as: [customernumber] equal to 151
4. check the live preview again
5. finish the chart builder and reopen

actual result:
chart live preview does not work after step4 unless reopen the chart builder in step5

expect result:
chart live preview after step4
it is a cache issue, fixed by clearing previous max line settings in data engine while filter is set on, it ensures chart gets expected data.
