Frank, many thanks for your reply.
I need some further assistance. using the provided code, the labels can now be produced at the last point on the chart. However, this is not very useful as it is not necessary that all series on the graph would have data available and hence as a result some of the series do not have the label. secondly, it would be good to have this label on the first point on each series.
Is there any way this could be acheived?
Thanks for being helpful.
