Dear developers!  
When I am visualizing volatility\_plot.qzv (Feature volatility) with big dataset and uncollapsed table I receive empty plot in vizualiser (I think, the problem just in visualizing in the browser).

 ![Screenshot%20from%202019-05-07%2009-56-11](https://forum-qiime2-org.s3.dualstack.us-west-2.amazonaws.com/original/2X/3/3f04461534702bd9387a4e6c9ce42eedbdbf16f3.png)

If I do the same with smaller dataset everything is working. Also, I can collapse my table and its works as well.

And sometimes, plot just suddenly starts to collapse by itself without any actions from my side.

If I will resize my browser and then resize it back the view becoming normal again until I move mouse a little bit.  
I encountered this problem many times on Chrome and FireFox. I also increased max memory limit in FireFox but still having the same issue.  
In general, I received everything I wanted from those plots, just reporting this issue here.

Thanks for reporting @timanix!

You are correct, this is a browser issue; if you have too much data in the volatility plot (e.g., too many features), then the browser will not load the visualization properly. Sounds like you figured out the solution: filter out features (e.g., collapse or filter out low-abundance features).

[This is a known bug](https://github.com/qiime2/q2-longitudinal/issues/135) that we plan to fix in a future release. Thank you for reporting!
