No legend from Emperor PCA visualisation with 2019.10 .qzv

Hi, I am currently running qiime2-2019.10.

When I attempt to export PCAs from Emperor, I only get the plot and not the legend. I have tried on many different browsers and on other PCs as per a previous closed thread in addition to re-generating the .qzv from the same qiime2 version. I tried again, using a .qzv generated from qiime2-2019.7 using the exact command with the exact same data and reloaded that in to Qiime2View. I was then able to download both the legend and the plot from the visualisation. I suspect a possible bug in how the .qzv files are handled.

Hi @BuildableDuck,
This issue looks to be a known one and similar to the one posted here a little back ago. The recommendation there was to check with your popup blocker (try disabling it or whitelisting qiime2 view) or maybe try with a different browser if its still an issue.
Try those first :crossed_fingers: and we’ll go from there.

Thanks for the reply @Mehrbod_Estaki . the thread you linked was the one I was referring to. I doubt its popup blockers as I used the same browser sessions with my trial and error. I had also whitelisted the View site in one of my attempts, but it did not appear to make any sort of difference. The only thing that appeared to make a difference was an older version of qiime2.

Thanks @BuildableDuck for trying those solutions. I’m not really sure what to offer here as a solution, let’s see if @yoshiki, the developer of Emperor has any suggestions.

Thanks for reporting this issue, I’ve looked into it and it looks like there’s a bug. I’ve opened a ticket in our GitHub repository and will look to address this before the next release. Thanks for reaching out!
