Dear Contributors,
I have two data. A is of the form:

B is extracted from A and I wish to plot A and B on the same x-axis
but different y axis on the same graph. Stacking very close helps to
illustrates the common rapid variations in A, represented in B.

One of the codes I tried without success is:
data <- read.table("A", col.names = c("year", "month", "day", "counts"))

new.century <- data$year < 50

data$year <- ifelse(new.century, data$year + 2000, data$year + 1900)

data$date <- as.Date(ISOdate(data$year, data$month, data$day))
x1 = data$date
y1=data$counts
#y1=scale(data$counts)


data <- read.table("B", col.names = c("year", "month", "day", "counts"))

new.century <- data$year < 50

data$year <- ifelse(new.century, data$year + 2000, data$year + 1900)

data$date <- as.Date(ISOdate(data$year, data$month, data$day))
x2 = data$date
y2=data$counts


pdf("PLOT.pdf")

 par(mar=c(5,5,5,5))

plot(x1,y1,pch=0,type="b",col="red",yaxt="n",ylim=c(-5.470919,1.298329),ylab="")
axis(side=2, at=c(-6,0,2))
mtext("red line", side = 2, line=2.5, at=0)

par(new=TRUE)
plot(x2,y2,pch=1,type="b",col="blue",yaxt="n",ylim=c(-4.808186,0.0), ylab="")
axis(side=4, at=c(-5,-1,0), labels=c("98%","100%","102%"))
mtext("blue line", side=4, line=2.5, at=100)
dev.off()

Your assistance is ever appreciated.
Best wishes
