The spike plot don't work when run at brower

Hello everyone, as you can see in the picture, the spike plot not work while others plot work well.

I have tested all the examples, they all has this problem.

MY OS is Ubuntu 20.04 with Anaconda 3 (python 3.8).

Hi @chunfeng_tsin, and welcome to the Nengo forums! :smiley:

Yes, we are aware of this issue. This is a compatibility issue between Nengo and NengoGUI (we are working on releasing a new version of NengoGUI shortly). While that is being worked on, the fix is to downgrade your Nengo version to 3.0.0 (i.e., pip install nengo==3.0.0).

EDIT: I’ve been informed that a new version of NengoGUI has been released, so doing pip install --upgrade nengo-gui should also address your issue.
