Thanks the GD::Graph::lines Graph worked it created a file that I can display. Here is what I'm trying to graph: Net Debit - Premiums Bought - Premiums sold (47.375 + 7.625) - 21.125 = 33.875 Max Risk - Net Debit 33.875 = $1,693.75 Max Reward - Difference in adjacent strikes - net debit 60 - 33.875 = 26.125 = 5000 X .26125 = $1,30625 Breakeven Down - Lower Strike + net debit 640 + 33.875 = 673.875 Breakeven Up - Higher strike - net debit 760 - 33.875 = 726.125 or 733.875 If entered below curent Strike price Max ROI 290.63% if the stock is priced at $700.00 at expiration How do I enter it into the code: <code> @data = ( "1st","2nd","3rd","4th","5th","6th","7th", "8th", "9th", 1, 2, 5, 6, 3, 1.5, 1, 3, 4, sort { $a <=> $b } (1, 2, 5, 6, 3, 1.5, 1, 3, 4) ); <code>
