I use qiime2 with the 2018.8 version.
The command I ran is--
$ qiime emperor plot
The emperor plot I generated is here.weightedUnifrac-emperor-TimepointByHour.qzv (812.5 KB) It has a customized axis called "TimepointByHour", which contains values like 0,4,8,12,16,..., 24,48.
My question is, how can I put the marks of values in "TimepointByHour" on the customized axis in the PCoA plot?
Thanks in advance.
