Add bars to a track
spiral_bars(pos, value, baseline = get_track_data("ymin", track_index), bar_width = min(diff(pos)), gp = gpar(), track_index = current_track_index())
pos |
X-locations of the center of bars. |
value |
Height of bars. The value can be a simple numeric vector, or a matrix. |
baseline |
Baseline of the bars. Note it only works when |
bar_width |
Width of bars. |
gp |
Graphical parameters. |
track_index |
Index of the track. |
No value is returned.
