Transform the data on te x-y graph from pdf to excel

Transform the data on te x-y graph from pdf to excel

(OP)
Dear Master

Could you please tell me how to transform the following attached pdf x-y graph data to the excel ?

Since I saw someone do this trick and made a Multiple regression equation so that we can plug a variable to

get the answer we want.

Thank you very much for your suggestion and guidance.

RE: Transform the data on te x-y graph from pdf to excel

Not without some conversion software. I use a program called Tracer, but it requires considerable cleanup of the graph to properly digitize the curves which have to be present individually for Tracer to do a good job. I normally use Paint.net to make clean copies of each curve separately for Tracer. This involves removing the markers, for example, as they'll tend to make the digitized curves "lumpy," as well as removing extraneous graphics.

I've had some success using engauge digitizer (free); like IRstuff, it required some manual intervention.

http://arohatgi.info/WebPlotDigitizer/ is free at least (Not sure why I got the wrong link in there)

Seems to do what Tracer does, more or less, but seems to have a couple of nicer features. I haven't actually tried to use it yet, though

I've always liked Digitize It from ALcAsA. Some scaling and clicking on points is required.

Doug,

I've used "GetData Graph Digitizer" for many years and it performed well. I downloaded your spread sheet and tried it. It works like a charm and I intend to use it from now on. Thanks!
