Missing Pieces of Waveform

Hi,

 

I am attempting to display 3 waveforms on a chart using live data samples. The waveforms draw ok in terms of the samples being in sync with each other, however parts of the waveforms are missing. (see attached screen shot, there is only one waveform shown for clarity)

 

I am using the sweep mode and sections between points are missing, however when I set it to either of the other 2 modes the missing lines appear and the chart is drawn normally. I really need to use the sweep mode for the visual aspect so really need to get this sorted.

 

I am measuring the surface of a round shaft and take a sample every degree, so obviously the chart is 360 samples long and then starts from the beginning at 0 degrees.

 

Thanks in advance!

 

Darren.
