Yes, that's clear, and seems that's mathmatics problem, have you tried to use round ( ) ? > > > I thougt I can make a factor and then multiply all the > > > other values with this on to get this result.

You can try to use a loop for simplifying the above... > > > My Prob: > > > I does not work every time. On some data input the columns are bigger than > > 580 pixel. Such as what kind of data ? above 100% ? In case, does $max_percent_value something like 0.2 or 20 for representing 20%, and what about the percent_value_x ? > > > > > > I also try, calculate without storing the factor in a string > > > (avoid mistakes by rounding...I don't know) like this: > > > > > > my $maximum_pixel = 580; > > > my $column_lengt_a = $percent_value_a * $maximum_pixel; > > > but this cannot let the hightest % give 580 pixels. You better have another new try for your first idea. =) Rgds, Connie
