setDimensionFilter with MemberInfo Object with TimeRange possible?

Hi,

I am using two InputFields to set a TimeRange for several Charts with setDimensionFilter. Is there any chance to do this with MemberInfo Object because setDimensionFilter is very slow in my case (~7-8sec). I tried it in many ways, but it did'nt work.

var range = TimeRange.create(TimeRangeGranularity.Day, new Date(year1,month1,day1),new Date(year2,month2,day2));
Chart_1.getDataSource().setDimensionFilter("0CALDAY",range);
