We have a stacked area chart which is a time series chart with dates along the x axis. We have long periods where data is missing and the chart is filling in that space by connecting the last valid date with the next valid one which results in a straight line/area drawn between the two. Is it possible to tell highcharts to not show anything in this space for a stacked area chart? So do not interpolate? I did try the connectNulls property and set it to false but that had no effect.
