Joh, thank you very much. sorry for confusing you. I didn't make my question clear. I tried your code it looks much better than my original one. Just I prefer I can write the greek letter delta1 and delta 2 instead of words 'delta1' and 'delta2'. Also, it will be nice if there is a square symbol next to delta1 and a circle symbol next to delta 2, since sometimes I have to print the graph in a white and black paper. Thanks for any suggestions. Sorry for not asking question clearly.
