Is there a way to adjust the zoom in q2-emperor? I ask because some of my Emperor-visualizations are generated too "close" to the plot, making it impossible to get an optimally useful angle.
That's what I see first of all, and consequently---to take just one problem---I can't see the tips of all three axes at once while simultaneously having a useful view of the samples. The frame of the visualization seems to have cut as nearly as possible to the two most distant samples.
And I know Emperor can do what I want, because with the same samples, Emperor also gave me this biplot:
Is the difference that the too-close one is Aitchison distance, and the useful one is unweighted UniFrac distance? Please tell me that's not the constraint.
Does anyone know a way to zoom out, or more generally, to adjust the zoom/frame in Emperor? Or failing that, if I export the biplot.qza and get the ordination.txt as a result, who knows if there's some other resource I can plug it into and get another try at this plot? I couldn't seem to find an answer in the forum or documentation, and am asking in this category thinking q2-emperor is a core rather than a community plugin. Running qiime2-2021.2 in conda.
If you have a mouse with a scroll wheel, put your mouse over the plot and scroll down to zoom out and up to zoom in. On many touchpads there is similar support, for example using 2 fingers on an Apple touchpad emulates the scroll-wheel functionality.
The camera controls are listed here:
Orbit - left mouse / touch: one-finger move
Zoom - middle mouse, or mousewheel / touch: two-finger spread or squish
Pan - right mouse, or left mouse + ctrl/meta/shiftKey, or arrow keys / touch: two-finger move
There might be some keyboard shortcuts, too: @yoshiki?
Also, another potential option is to open your plot in the experimental Vega editor:
Keep us posted.

PS - on a general note, it looks like something might be off with how Emperor is computing/measuring your computer's screen resolution - the size of the plot text is huge compared to the control text, on the right hand side of the screen. Which size text is more common on your computer, the large text in the plot, or the small stuff on the right?
