O candy ...
u just start the axis from 0... this date is assumed to be continuous ...
so if the bars touch each other .... they take the lower boundary into consideration..
so as u said it toucehs each other.... thts perfectly alright

how can i start from 0 when my FIRST lower boundary is 0.05 ...so that means i need to start my graph from 0.05...but when i try to start from 0.05 it touches the 0 line....so how much should should i take my axis as?
because in the markscheme they have haven't started from 0..there is a gap b/w the chart and 0
this question is from may june 2008 question 5

usually graphs hav 10 small blocks which makeup a one big lbock:P
so eacho f ur one bl0ck is 0.1 so u beign with 0.1
