const filterX = (cmp)  => {
  return cmp.getSpec().orient === 'bottom'
}

vchart.setDimensionIndex(50, {
    filter: filterY,
    crosshair: true,
    tooltip: false
})

vchart.setDimensionIndex('Round 1', {
    filter: filterX,
    crosshair: true,
    tooltip: false

// Just for the convenience of console debugging, DO NOT COPY!

Research direction

Start by running the supplied line-chart reproduction and inspect the setDimensionIndex path for crosshair handling, especially the y-axis filter and bindingAxesIndex configuration. Compare it with the working x-axis case. Done means setDimensionIndex(50, ...) displays the linear y-axis crosshair as expected without regressing the x-axis behavior.
