I have this plot:
Where:
- Orange vertical line is false positive of p-wave class
- Green vertical line is false positive of qrs-wave class
- Purple vertical line is false positive of t-wave class
- Red vertical line is false positive of baseline class
But, the legend of false positive is black, it showed as horizontal line. Yeah, it’s because I use axvline at x=0 with specify black color so that it looks like hidden.
I expect instead of black, it should be colorful especially red, orange, green, and purple at same portion drawed horizontally.
