I don't think that I would use a barplot as the base, but rather just set up the graph and add the lines where I wanted them. I still don't understand what you want your graph to look like, or what question you are trying to answer with it (part may be a language barrier). If you can give us a better example of what you are trying to accomplish, or a better description of what your data is like and what you are trying to get from the graph, we will have a better chance of being able to help you.

I am using lend as it suits to me more as gregory suggested , but I am not getting imite??? think I try to fix it with some other method also, as I have to deal more with the symbols in this case, But I want to the know one thing from you guys that the way I am using the code is good enough to start, as I am not much familiar with this suff or its dirty way to handle such task. please let me know. Thanks gregory and petr.

If not, the lend argument (see ?par) may be something to look at. If you really want points and segments you will need to plot the points with the points function and the segments separately. Segments can take vectors, so you don't need to separate things into multiple calls. -- Gregory (Greg) L.

I want to draw different shapes for every chunk of segments i.e is the whole point. I want to make script which can generate such figures, below is link to one of the tool. http://www.expasy.ch/tools/mydomains/ Thank you Jeet On Thu, Jun 10, 2010 at 11:10 PM, Greg Snow <greg.s...@imail.org<mailto:greg.s...@imail.org>> wrote: Your question is not really clear, do either of these examples do what you want? with(anscombe, plot(x1, y2, ylim=range(y2,y3)) ) with(anscombe, points(x1, y3, col='blue', pch=2) ) with(anscombe, segments(x1, y2, x1, y3, col=ifelse( y2>y3, 'green','red') ) ) with(anscombe, plot(x1, y2, ylim=range(y2,y3), type='n') ) with(anscombe[order(anscombe$x1),], polygon( c( x1,rev(x1) ), c(y2, rev(y3)), col='grey' ) ) -- Gregory (Greg) L.
