The given forum post is for the old RadChart, and you are using the new ChartView control, so it really is not applicable.
Well, depending on the exact result you need, you can use one or two approaches. The easiest way to go is to set the LabelFormat property of the axis (say "N0"). This will ensure that the values are shown without the decimal point. However if before you had labels 1, 1.2. 1.4, 1.6 ... it would now show 1, 1, 1, 1 .. so perhaps this is not what you need.
May be you need to use the template selector capabilities of the axis (LabelTemplateSelector). In the SelectTemplate override you can check whether this is a whole number and if it is not, you can return an empty template (so the label would not be visible). Let us know how it goes.
