Yup… one of the least understandable areas of the UI. I’d prefer the graph at a minimum had values on the axis to make it more obvious, such as the top being 100% and the bottom your configured value. The table beneath would also use real value and not a % of a %.
The most understandable would be the Y axis and table beneath using simple 0-100% (real values, not % of a %) and show the dots never going under the configured value you wish to stay over. Understandably it would vertically compress the line a bit, but I think these questions would disappear and anyone would understand what the chart and table are trying to show.
The way it is now has been causing confusion on the forum at least since I started using G2 early last year. I can’t imagine what people who don’t visit the forum think is happening.
