Hi magic_bern,

You should be able to use marker lines for this. Let me know if you have any troubles.

mwilliams,

Thanks for the help i was trying to figure out for a while how to get a line with the marker and i was about to give up when i just tried to create a serie and simply put in a value i.e 10.3 rather than an available data set and bang i had my horizontal line i was after and this time i used the maker to remove the funny things at linking points to get a clean straight line.

Thank you very much
