   Here’s a proposal for how you can extend Highcharts to draw a graphic for null points: http://jsfiddle.net/highcharts/FKSZ6/

   A refinement of this idea as follows. Instead of a broken line, use a definite symbol as in this image: http://stats.raveis.com/General/images/missingData.gif. The missing data symbol can be used in different chart types and, since it is unique, it can be unambiguously identified in user documentation as such (An outlined letter "x" represents missing or undefined data)
