Chart plot displays data incorrectly when viewed in multi-channel mode

Chart plots are intended for displaying epoch events (data lists), wave snippets or buffered signals in OpenController and for epoch events and spike snippets in OpenScope. When plotting continuous data (Stream) in multi-channel mode, the display shows a waveform for channel one, but not the others or there is a lag in the other channels relative to the first channel.


To view stream data use a Scroll plot. Although the x-axis of a Scroll plots cannot be changed dynamically as with the Chart plot, the x-axis (duration) can be changed in the plot settings to enable you to view the waveform in greater detail.

To modify the duration of a Scroll plot, perform the following steps:

  1. Double-click the Scroll plot control to display the Setup Properties dialog box.

  2. Change the number of scroll sections under the Common Parameter Group settings.

  3. Click OK.
