- data_bands
(
data.frame) a data frame with 3 variables named the following:level: level each band represents
ystart: starting point of each band
yend: ending point of each band
col: color of each band
- data_lines
(
data.frame) a data frame with 7 variables named the following:stage: stage each line represents
xstart: x-axis starting point of each line
xend: x-axis ending point of each line
y: y-axis position of each line
col: color of each line
xpos: x-axis position of each annotation (relative to xstart)
