Do you anticipate this playing well with charts that have multiple Y values for a given X value. For example, candlestick plotting <https://github.com/racket/plot/blob/9c8960d40772cc61211ff5d9ab185f9cf931b044/plot-lib/plot/private/plot2d/point.rkt#L254> has recently landed in racket/plot. It would be great to be able to show all of the values, or at least specify which of the open/high/low/close values to display.
