Helicopter Performance Chart

[KWpilot]

OK, here it goes. I'm a helicopter pilot and in the operator's manual of the aircraft is a performance section. What I'm trying to do is take the performance charts and convert them to excel. basically its a scatter chart with different variables. In short you take the temperature match it up to the pressure altitude and it gives you what you maximum gross mass is for those conditions. I wrote one chart on excel but I'm stuck on the data series which have been plotted but I don't know how to tell excel to go from the temperature to the the pressure altitude. My "Y" values are in the aircraft weight 2200-3350 and my "X" values are temperature -50 thru +50. the Data series is My pressure altitude is from 0-18000 feet. If I can some how attach a copy of my form it may give you a better understanding of what trying to do. any help or guidance would be appreciated.

Thanks

Joe
