Hi - I am

I did this YEARS ago on some very earlier versions of Excel, but am using Excel 2010 now - I have created a supply and demand graph for an economics project - but cannot remember for the life of me how to insert the equilibrium point and the dotted lines that then mark that, the P1/Q1 and P2/Q2 values - and have dotted lines for all three.

Please Help.

Regards

Hels
