Graphing a paper's number of citations by year The specific paper I'm interested in is Galton (1907), and one approach I worked out is to go to Galton's Google Scholar profile and then click on the paper in question, after which I can see the following histogram:



This is the kind of thing I want to create, but one problem is that it cuts off in 2005. 

If I click on the article itself and look within citing articles I can see there are several citations before 2005, but it wasn't apparent to me that there was a way to count them without manually going through each page. 

Is there a way for me to obtain data for the number of citations by year (including pre-2005) without manually going through the citing articles?

If you have access to Scopus (Web of Science also works, I presume) you can show the publications citing this paper in search format. Using the filters on that search page, you can retrieve the data you're looking for quite easily (year filter > show more > show all). In this case, that shows the following:


Problem with this, of course, is that Scopus only shows the citations it has in its database (410 documents).
