Often one well-designed figure can replace several figures lifted from the literature. Be prepared to replot experimental results especially in the light of improved understanding. The captions should be self-contained. Imagine that the reader has only the captioned figures and tables to figure out what you have done. Consider adding figures and tables that illustrate and summarize the material.
Tables are very useful for making comparisons.
As a start see if all your basic conclusions can be summarized in one or more tables. Please avoid acronyms. There are a very few that are o.k. In most cases acronyms interfer with the reading. RMP is quite prepared to pay for the extra ink and paper.
