Highchart displaying data with some null points (only visible via tooltip if marker disabled):

Enabling markers will resolve the issue of invisible points, but it may look cluttered with many points:

Does anyone have a suggestion on how to make a single point more visible without overcrowding the chart with markers? Specifically, I only want to display markers on individual points.
