У меня трехпанельный дисплей в ggplot2. Панели расположены вертикально друг над другом.
Я пытаюсь добавить три вертикальные линии, которые пересекают панели. Другими словами, вертикальные линии не должны обрезаться до областей построения . Вот что я хочу:
Однако, когда я использую встроенный ggplot2::geom_hline() (так как координаты перевернуты на этом графике), я получаю это:
После ознакомления с предыдущими решениями (например, здесь и здесь ) я решил попробовать решения, использующие gtable, чтобы изменить макет графика и / или добавить дополнительные пометки, используя gtable_add_grob.
Я пытался использовать gtable_add_grob в сочетании с комбинацией moveToGrob и lineToGrob ( здесь ) или segmentsGrob ( здесь ), но ни решили мою проблему. moveToGrob и lineToGrob, кажется, работают только с одной вертикальной линией, и я хочу несколько; segmentsGrob, кажется, применяется только к одной области построения.
Я довольно запутался в этом вопросе. У кого-нибудь есть совет?
