I’m trying to create a polynomial formula it could be a 3rd degree to a 6th degree it doesn’t matter how long the formula is I just need it to be accurate and be able to extrapolate as accurately as possibly if the x or y data inputted is off the ends of the chart. Attached is the example of the data that I’m referencing I would like to get a code that I could edit and run myself as I have about 20 similar charts that I want to extrapolate a formula for. I need to be only a temp(y) and a humidity(x) and have the formula spit out (z) and it be accurate based off the chart.I’m trying to create a polynomial formula it could be a 3rd degree to a 6th degree it doesn’t matter how long the formula is I just need it to be accurate and be able to extrapolate as accurately as possibly if the x or y data inputted is off the ends of the chart.
