```Hi

In ancient times I developped function plot.yy which requires some data twisting but should do plotting with one x axis and two y axes and should estimete ranges automatically.

datA <- data.frame(datum=x1, counts=y1)
datA\$vzor <- "A"
datB <- data.frame(datum=x2, counts=y2)
datB\$vzor <- "B"
mydat <- merge(datA, datB, all=T, by="datum")

plot.yy(mydat\$datum, mydat\$counts.x, mydat\$counts.y, col=c("red", "blue"), linky=T)

## The function is currently defined as
plot.yy <- function (x, yright, yleft, yleftlim = NULL, yrightlim = NULL,
xlab = NULL, yylab = list(NA, NA), pch = c(1, 2),
col = c(1,2), linky = F, smooth = 0, lwds = 1, length = 10,
format = "%d/%m", rect = NULL, type = "p", ...)
{
par(mar = c(5, 4, 4, 2), oma = c(0, 0, 0, 3))
plot(x, yright, ylim = yrightlim, axes = F, ylab = "", xlab = xlab,
pch = pch[1], col = col[1], type = type, ...)
if (!is.null(rect))
rect(x[rect[1]], rect[2], x[rect[3]], rect[4], col = "grey")
points(x, yright, ylim = yrightlim, ylab = "", xlab = xlab,
pch = pch[1], col = col[1], ...)
axis(4, pretty(range(yright, na.rm = T), 10), col = col[1])
lines(x, yright, col = col[1], ...)
if (smooth != 0)
lines(supsmu(x, yright, span = smooth), col = col[1],
lwd = lwds, ...)
if (is.na(yylab[[1]]))
mtext(deparse(substitute(yright)), side = 4, outer = T,
line = 1, col = col[1], ...)
else mtext(yylab[[1]], side = 4, outer = T, line = 1, col = col[1],
...)
par(new = T)
plot(x, yleft, ylim = yleftlim, ylab = "", axes = F, xlab = xlab,
pch = pch[2], col = col[2], ...)
box()
axis(2, pretty(range(yleft, na.rm = T), 10), col = col[2],
col.axis = col[2])
if (!inherits(x, c("Date", "POSIXt")))
axis(1, pretty(range(x, na.rm = T), 10))
else {
if (inherits(x, "POSIXt")) {
l <- length(x)
axis(1, at = x[seq(1, l, length = length)],
labels = format(as.POSIXct(x[seq(1,l, length = length)]),
format = format))
}
else {
if (inherits(x, "Date")) {
l <- length(x)
axis(1, at = x[seq(1, l, length = length)],
labels = format(as.Date(x[seq(1,l, length = length)]),
format = format))
}
else {
print("Not suitable x axis")
}
}
}
if (is.na(yylab[[2]]))
mtext(deparse(substitute(yleft)), side = 2, line = 2,
col = col[2], ...)
else mtext(yylab[[2]], side = 2, line = 2, col = col[2],
...)
lines(x, yleft, col = col[2], lty = 2, ...)
if (smooth != 0)
