Hi Mamun, You can get two different scales e.g. 0-10 on the left and 7-9 on the right, but you will want to color code the two axes and plots so that the viewer knows which plot goes with which scale. If you want to try this, look at twoord.plot in the plotrix package.

Re: [R] Over lay 2 scale in same plot
Hi Mamum, You can look at the ylim argument to plot(). It lets you control the limits; however, in your example graph, part of the issue is that the bars have a much higher value, so you could not change ylim too much (looks like in your example graph you could set it to something like ylim = c(0, 7) ? ).

Re: [R] Over lay 2 scale in same plot
Hi Peng, Thanks for your reply. I have tried it and it does work fine apart from one problem. Even though the second data set has same length as the first one, the point function seems to shit all the points towards left side. So the points are not in concordat co-ordinates as the bars. Any idea how this can be fixed ??? thanks in advace. regards, Mamun -- View this message in context: http://r.789695.n4.nabble.com/Over-lay-2-scale-in-same-plot-tp2528661p2531255.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
Re: [R] Over lay 2 scale in same plot
Hi Mamum, The co-ordinates appear shifted because the bars are not centered at 1, 2, 3, etc. To give an example: # Create a barplot # of the numbers 1 through 10 barplot(1:10) # Now look at the x axis coordinates of these actual bars barplot(1:10, plot = FALSE) # One way to get these coordinates for yourself would be x - barplot(1:10) # this will plot AND save the object x # see the coordinates # This should have the points properly centered with the bars points(x = x, y = 10:1) HTH, Josh On Wed, Sep 8, 2010 at 6:14 AM, mamunbabu2001 mrashi...@hotmail.com wrote: Hi Peng, Thanks for your reply.

Re: [R] Over lay 2 scale in same plot
Hi, Looking at the picture, I think you are just talking about plotting two datasets. Here is an example I made up, that looks sort of like your picture: # make a barplot barplot(-50:50) # add points into the existing plot at the coordinates set by x and y # and use a line to connect them points(x = 1:101, y = seq(from = 30, to = -20, length.out = 101), type = l) Do you have some sample data you could send us of what you are trying to plot? We can give more specific feedback if we have some actual data to work with. Hope that helps, Josh On Mon, Sep 6, 2010 at 9:57 AM, mamunbabu2001 mrashi...@hotmail.com wrote: Hi Everyone, I have two different data set in 2 different scale.
