Next, I have more data that should be expressed as a bar chart or straight
lines, the data is below. I want these bars or lines to be on my line chart
(S curve graph). Each issue should appear as a line or bar. Each issue
should begine on its start date & end on its end date. This is the chart I
have not been able to create & once it is created I need to put it on the
line chart (S curve graph). Can both be put on one chart or must I make 2 &
how?
