Tried all permutations with styling, but didn’t quite get the grid lines or ticks to disappear. When I inspect the elements, the Highcharts styling looks right, but the grid lines are still visible.
FYI, I tried to follow what is outlined in this documentation but to no avail:
https://vaadin.com/docs/v10/charts/java-api/css-styling.html
Wondering if anyone has done any styling for Charts?
