Remarks

This method adds one data point to the DataPointCollection object, always adding it to the end of the collection.

Use the method definition that allows for an array of Y-values if your data points require more than one Y-value.

If your data points do not need an X-value (e.g. if you are creating non-scatter plots) then use the AddY method instead.
