Identical values for X and Y will always display points on a straight line. Is there a use-case where this is useful ?

I could see it being somewhat useful for candlestick series.

Using custom graphics to locate the problem, it should be that the parameters in encode were lost during processing.

Here is another way of getting the same result without encode and custom series - Demo Code.
