Most probably the cause of the problem is that you have set a value format for the Y axis that trims the numbers after the decimal separator (rounds them to integers), such as F0. So the chart is displaying
0, 0, 1, 1 instead of 0, 0.5, 1, 1.5. To change that you need to use the CustomFormat
property of the axis, to something like "G" for example. You can also use the ValueFormat
property, which gives you a set of predefined options, to choose from.
I hope this helps.
