Comment (by karsten):

 Here's a graph roughly like the one I suggested above:

 [[Image(exitips-stacked-area.png​, 700px)]]

 Here's the source code:

 {{{
 require(tidyr)
 require(dplyr)
 require(readr)
 require(ggplot2)

 read_csv("exitips.csv", col_types = cols(
       time = col_datetime(format = ""),
       consensus = col_double(),
       exitl = col_double(),
       exitlo = col_double())) %>%
   transmute(time, consensus_only = consensus - exitl + exitlo,
     both = exitl - exitlo,
     exitlist_only = exitlo) %>%
   gather(document, ips, 2:4) %>%
   mutate(document = factor(document,
     levels = c("exitlist_only", "both", "consensus_only"),
     labels = c("Found only in exit list",
       "Found in consensus and exit list", "Found only in consensus"))) %>%
   ggplot(aes(x = time, y = ips, fill = document)) +
   geom_area() +
   scale_x_datetime(name = "") +
   scale_y_continuous(name = "", limits = c(0, NA)) +
   scale_fill_manual(name = "",
     values = c("#03B3FF", "#39FF02", "#FFFF00"))
 ggsave(filename = "exitips-stacked-area.png", width = 8, height = 5, dpi =
 150)
 }}}
