Basic feature comparisons (e.g. amount of L3 cache):
Plot of Xeon 7500-series L3 Cache size

png( filename="plot.png", width=640, height=440, bg="#070707" );
par(bg="#070707", fg="white", col.axis="white", col.main="white", col.lab="white", mar=c(3,4,2,2) + 0.1);
plot(xeon$Model, xeon$L3.Cache, ylab="L3 Cache", border=brewer.pal(8, "Dark2"), cex.axis=1.3, cex.lab=1.5);
dev.off();

Two-factor comparisons (e.g. with and without turbo boost):
Plot of Xeon 7500-series Processor Frequency and Turbo Boost

png( filename="plot.png", width=640, height=440, bg="#070707" );
par(bg="#070707", fg="white", col.axis="white", col.main="white", col.lab="white", mar=c(3,4,2,2) + 0.1);
plot(xeon$Model, xeon$Frequency, ylab="Processor Frequency", ylim=c(1.8,2.8), border=brewer.pal(8, "Dark2"), cex.axis=1.3, cex.lab=1.5)
points(xeon$Model, xeon$Frequency..Turbo., col=brewer.pal(8, "Dark2"), pch=19)
dev.off();

  1. I came back 3 years later and couldn’t figure out what was happening. My point colors weren’t matching up with the bar colors.

    It turned out the points were being drawn in reverse order of the bars (which mixed up all the colors). The plot() functions above didn’t need any changes, but the color palette must be reversed inside the points() function:
    points(xeon$Model, xeon$Frequency..Turbo., col=rev(brewer.pal(8, "Dark2")), pch=19)
