I'm looking for a way to show where is a point of return of investment is happening thru out the year. So, I want to have a chart of bars where each bar is the income of a certain month (Jan-Dec) and all previous months (shows total profit up until this month), and all of this is shown in reference to a number that represent the investment amount.
for example: Jan - $100 Feb- $200 March - $300 .. .. Dec - $1200
Investment is $600.
So the chart will show all 12 bars: - where Jan-Feb will be below the X axis (which is $600), each in different height of course. - March - will be exactly on the X axis line, because Jan-Feb-March sums up to $600. - this is where I return my investment. - Apr-Dec will be above the line (which is $600), each in different height of course... where Dec shows $7800 (100+200+300...+1200)
I hope I managed to explain myself.
Basically - an ROI or PB chart :)
Thanks.
