calculate individual serial no. readings from text file and plot graph

[nyp123]

HI Guys. i need to calculate the efficiency of power of two solar planels and plot the graph, which these two solar planels have different serial no. respectively 2000776729(ThinFilm) and 2000776707(Poly). The input power formula for Poly= B2*0.6566*12 and Thinfilm=B2*1.4493*9. B2 is the column of int_ana File.

The output formula is Vdc*Idc which is Column E* column I.

Efficiency formula is  the (ouput of the power/input of the power)*100%.

The serials no. of the planels are found in the Int_sma file column D.I need to extract them out indiviually and calculate. Need help please

And also indicate what kind of help you're looking for. Specific help, not "write the code for me" kind of help.

Sorry about that. As the int_sma have 2 different serials no. for solar planel, i do not know how to extract them and place them together to plot graph.

I also do not know how to extract data from the specify column to plot graph.
