group marker group marker lines RESOLVED

[Silvio.Falconi]

How can I go about drawing the thickest lines but only the marker lines for each group?
ie only the lines marked with red arrows?

[Silvio.Falconi]

I resolved with

FOR i := 1 TO 1
oCol := :aCols[ i ]
oCol:nColDividerStyle := LINESTYLE_BLACK
NEXT

FOR i := 6 TO 56 STEP 5
oCol := :aCols[ i ]
oCol:nColDividerStyle := LINESTYLE_BLACK
NEXT

But I not Know if it's Right

Dear Silvio,

Will we win the lotto ?

You are becoming a Master of it

Is there a lottery in espana?
tell me if I can make sone predictions, so you'll win sure

I know that in spain there is the Primitiva which is a lottery with six numbers + a complementary, probably my functions also run for the primitive with small changes, but without an archive I cannot make statistics, I have found an archive from 1985 to 2014 in txt format, I don't know where to found the extractions up to the current date to make predictions, to calculate late numbers and other statistics.
