Lakshmi, please make sure that you insert linebreaks in your posts. It's rather annoying that every second one of them has lines so long as to completely break the layout. Please edit your last post so that it displays correctly.
OK, I think I got it now - you don't want labels like the ones shown in the example (apple, banana, etc.), you want labels for the individuals bars. It's not possible to put those directly underneath the bars. That's what the legend is for (Peter, Helga, etc. in that example).
Is there anyway we can reduce the size of the charts. For example in the above example, what you have given for apples, pies, bannans and oranges of Vertical Bar. I want to make it very thin charts, basically reduce it to very thin size not so much wide.
