I made several plots and figures. About 20% of data I used to make a plot came from papers of other people, which I'm surely going to cite in a common manner. But the other 80% percent of data I collected on my own during the research, so I'd like to point it out in the figure's caption (otherwise a person who reads my article would have gone to the cited paper and found there only 20% of data).

What is the proper way of doing this? Should it look like that (example picture is taken from here):

Fig. 1. Dependence of Y on X within different groups [123, own dataset].

where:

• 123 is the ordered number of an external dataset reference in the reference list;
• own dataset - an attempt to reference my own data.
