Basic ggplot question
Hi, Try this, m = melt(dat, id="Date") head(m) qplot(Date, value, data=m, colour=variable, geom="line") ggplot(m) + facet_grid(variable~., scales="free_y") + geom_path(aes(Date, value)) HTH, baptiste

Hello R-Group, I am trying plotting simple time-series with ggplot2 because the output looks better and I've heard its richer in features. I have the following dataset.
dput(dat)
structure(list(Date = structure(c(14970, 14971, 14972, 14973,
14974, 14977, 14978, 14979, 14980, 14981), class = "Date"), Close =
c(5998.1,
5996, 6060.35, 6101.85, 6134.5, 6157.6, 6146.35, 6079.8, 6048.25,
5904.6), vol = c(0.154535414667409, 0.151830297402932, 0.140309395040681,
0.136253183394409, 0.137108091041075, 0.137109537791588, 0.137664093371524,
0.141313700592413, 0.123866294210121, 0.139356235990631)), .Names =
c("Date",
"Close", "vol"), row.names = c("4905", "4906", "4907", "4908",
"4909", "4910", "4911", "4912", "4913", "4914"), class = "data.frame")
I can get one plot using:
qplot(Date, Close, data=dat,geom="line")
How can I plot both Close and vol on the same chart?
Been breaking my head on this ... thanks for your help in advance.
Regards,
S
