I have several data series plotted on a chart. This is logged data spanning several hours. However, there is occasionally a period of 30 minutes where no data is logged. This causes the chart to draw a line between the last sample before logging stopped and the first sample when logging resumes.

This can appear quite misleading where sudden jumps in data appear. It is preferable to show that there is not logged data in this period.

Is there any way to tell the series not to plot data between two points? So it would still be one series, but with a break in the middle.
