Description (last modified by )
If we build these series in TOLBase, s1 and s2 are charted very fast, in less than 1 second. However s3 takes a long time until it's displayed.
Date from = y2000; Date until = y2009; Serie s1 = SubSer(Gaussian(0,1,C),from,until); Serie s2 = SubSer(CalInd(WD(1)+WD(3)+WD(5)+WD(7),C),from,until); Serie s3 = IfSer(s2,s1,?);
If we show a table or we make any other calculation there is no difference in evaluation time between these series.

The pair of files test.tol and test_rbc.tcl is able to generate the graph of series in: 0.24588 s
The package RBC ( http://wiki.tcl.tk/24533 )is a good candidate to replace BLT and should be considered in the tickets related to milestone TOLBase Revitalization
Note: See
TracTickets for help on using
tickets.
It is also very confusing that points isolated between unknown values were not drawn in any way. Can not be a segment due to they have no other point to be joined with it, but it should be a point or some kind of user selectable mark.
