Thanks Romain for trying to help, but my issue is that I have three time series, not two, so at least two of them would have to go on the same side.
There may be no solution to this problem in R but if there is, would appreciate hearing about it from someone ? Figure 1 in this link shows what I am trying to achieve: http://www.aditus.nu/jpgraph/howto04.php Thanks anyway, Tolga Romain Francois <[EMAIL PROTECTED]> 30/06/2008 10:51 To [EMAIL PROTECTED] cc Matt Aldridge <[EMAIL PROTECTED]> Subject Re: [R] Plotting three time series on the same graph Hello Tolga, I am not sure what you are looking for is achievable easily, however, you can have an axis on the left and another on the right. Look at the side argument of the axis function. Would the following code work for you: # generating some data y <- 1:100 + runif( 100, min = -10, max = 10 ) x <- 1:100 + runif( 100, min = -10, max = 10 ) z <- seq( 70000, 25000, length.out = 100) + runif( 100, min = -2000, max = 2000) # prettier version of lines .myLines <- function(x,y, col = "blue", lwd = 2, ...){ lines( x,y,col = "black", lwd=2 + lwd) lines( x,y,col = col, lwd=lwd, ...) } # transform from the scale c(25000,70000) to (0,100) transform <- function( data ){ ( data - 25000 ) / ( 70000 - 25000 ) * 100 } par( mar = c(5,4,4,4)+.1 ) plot( 1:100, x , type = "n", las = 1 ) axs <- pretty( c(25000, 70000), n = 5 ) abline( h = transform(axs), col = "gray") .myLines( 1:100, x, col = "red" ) .myLines( 1:100, y, col = "blue" ) .myLines( 1:100, transform(z), col = "green" ) axis( 4, transform(axs), axs, las = 1 ) Best Regards, Romain Francois -- Mango Solutions data analysis that delivers Tel: +44(0) 1249 76 77 00 Fax: +44(0) 1249 76 77 07 Mob: +44(0) 7813 52 61 23 R for finance course: 8th-10th july.
