I'm confused how having a negative karma on Reddit is not a sign that people on Reddit find you disagreeable. It's a metric designed to showcase one's agreeability or disagreeability. If more people agree with you than disagree with you: karma will largely reflect that. If it's consistently negative, people consistently disagree with you.
Having a trend over time allows for a better judgement as karma is a metric that can change drastically over time. A generally disagreeable person can have a huge spike in positive karma but that doesn't mean they're liked overall. So it helps that the chart shows as far back as 2013.
A slow overall increase with several downward trends means you're generally agreeable but have a controversial opinion (opposed to the "collective group mentality"). A slow overall decrease with an upward trend now and then means you're generally disagreeable and occasionally say something the community agrees with.
Her karma over time tells me that she's generally disagreeable with a few moments that brought her from "negative" to "neutral" and that before the subreddit bans her popularity was spiraling downwards, hit a full catalyst, and the apology was rather well received.
If her karma was overall positive and only trended negatively in light of the subreddit ban and the Victoria mishap - it'd be telling of a very different story. The fact that it's been consistently negative is telling of the larger picture.
