Plots with multiple curves displayed wrong in cml

I am getting beautiful pr curves with DVC, where I have a curve for each class on my plot.

I took what I had and created a cml pipeline and the result looked completely different/worse.

From dvc I run:

dvc plots diff

For the cml version I run:

dvc plots diff --target pr.csv --show-vega origin/main

For cml I used the docker image found on dockerhub, updated five days prior to my usage dvcorg/cml

@pared mentioned it might be due to fact that “file” results override flexible plots, as its parsed later, need to prepare a reproduction script.

@shortcipher3 created a PR to fix this: iterative/dvc#8114

@shortcipher3 thank you for the detailed steps, I was able to determine part of the issue.

The dvc plot being rendered via dvc plots diff --targets model_pr.csv main is in the regular vega format and the plot rendered via dvc plots diff --target model_pr.csv --show-vega main > vega.json is in the vega-lite format which differs slightly

there is probably a good way to programmatically extract the vega data embed on the index.html (in which case you can use vg2png instead of vl2png), but the quickest path to something workable would be to go:

dvc plots diff --targets model_pr.csv main
cml publish dvc_plots/index.html

cml publish with output a link like: https://asset.cml.dev/36855bf8a25c5882ce4c52ec85fc5d5f9f8f272f?cml=html which you can use in a report.md etc.

CC @daavoo @0x2b3bfa0 as feel they can probably recommend another approach?
