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

Hi Josh, Thanks for your reply. I gave a reply yesterday but found that it was not posted. I managed to plot the bar pot and overlay points. The problem I am facing now is the spread of Y scale. The values I am plotting in Y scale are very close. so they look pretty flat. (lowest value 7.5 and h

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 coordinat

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

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
