Steps to Reproduce

1. Draw a line chart
2. use dataset and encode to get data
3. use the same dimensions in encode.x and encode.y
4. the graph does not render

Current Behavior

the graph does not render

Expected Behavior

the graph render

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.
