While using two Loop in same JSL script like below, One is to draw Bivariate chart by different "ToGraphBy" another one is to add Spline for those charts with different Color (by "Flag") . however, as second Loop counts "Flag" from all table instead of each separated segment by "ToGraphBy" , that cause each segment charts points color mismatch with Spline color. Who can help us to modify this script a little big to make it more reasonable ?

```
dt = Current Data Table();
Summarize( dt, byVals = by( :TOGRAPHBY ) );
Summarize( dt, ByFlag = by(:Flag ) );
Bi = Bivariate( X( :LOT_DATA_COLLECT_DATE ), Y( :CHART_VALUE ), by( :TOGRAPHBY ));
For( i = 1, i <= N Items( byVals ), i++,
LCL = :LO_CONTROL_LMT[(dt << get rows where( :TOGRAPHBY == byVals[i] ))[1]];
UCL = :UP_CONTROL_LMT[(dt << get rows where( :TOGRAPHBY == byVals[i] ))[1]];
TGT = :TARGET[(dt << get rows where( :TOGRAPHBY == byVals[i] ))[1]];
chartMin = Min( :CHART_VALUE[dt << get rows where( :TOGRAPHBY == byVals[i])]);
chartMax = Max( :CHART_VALUE[dt << get rows where( :TOGRAPHBY == byVals[i])]);
If(LCL < chartMin, chartMin = LCL );
If(UCL > chartMax, chartMax = UCL );
chartRange5% = (chartMax - ChartMin)/5;
Gridset=(UCL - LCL)/5;
chartMin = chartMin - chartRange5%;
chartMax = chartMax + chartRange5%;
