Excel 2008 : Graph in Excel

Hi,

right ... so I'm making a graph for my thesis. My numbers are 0.3668, 0.5982, 0.3107, 0.648 in one phase and 0.4326, 0.6436, 0.3689, 0.6214 in the other phase. It's line graph showing 4 lines for 2 different phases. The problem is that the y-axis numbers on the side (the ones that should correspond to the individual numbers above) range from 0 to 3. I can't figure out why and I can't change it either. I tried setting min and max value, but then it won't show me all the lines .... I'm really confused and spend the last 3 days using excel.
PLEASE help me. Untitled.jpg

Thank you!!
