Hi all, I want to draw a line with the values of x marked in X axis. I tried with x <- c(0,6,12,18,24,30) #coordinates of points x y <- c(2,5,7,5,7,16) #coordinates of points y plot(x,type="n",xlab="Months",ylab="Y values",main="main",ylim=c(0,16),xlim=c(0,30)) lines(x,y) The graph shows by default an increment of the sequence in x axis that I'm not able to change. I'would like to have 0,6,12,18,24,30 and not 0,10,15,20,25,30. Any hint is appreciated. Thanks in advance.

Hello, you can do what you want by doing a call to axis, thus in the plot call you have to use : axes=F x <- c(0,6,12,18,24,30) #coordinates of points x y <- c(2,5,7,5,7,16) #coordinates of points y plot(x,type="n",xlab="Months",ylab="Y values",main="main",ylim=c(0,16),xlim=c(0,30),axes=F) axis(2) axis(1,(0:5)*6) lines(x,y) box() Romain
