Draw the Legends
Draw the Legends
## S4 method for signature 'Legends' draw(object, x = unit(0.5, "npc"), y = unit(0.5, "npc"), just = "centre", test = FALSE)
object |
The |
x |
The x position of the legends, measured in current viewport. |
y |
The y position of the legends, measured in current viewport. |
just |
Justification of the legends. |
test |
Only used for testing. |
In the legend grob, there should always be a viewport attached which is like a wrapper of
all the graphic elements in a legend.
If in the object, there is already a viewport attached, it will modify the x, y
and valid.just of the viewport. If there is not viewport attached, a viewport
with specified x, y and valid.just is created and attached.
You can also directly use grid.draw to draw the legend object, but you can
only control the position of the legends by first creating a parent viewport and adjusting
the position of the parent viewport.
lgd = Legend(at = 1:4, title = "foo")
draw(lgd, x = unit(0, "npc"), y = unit(0, "npc"), just = c("left", "bottom"))
# and a similar version of grid.draw
pushViewport(viewport(x = unit(0, "npc"), y = unit(0, "npc"), just = c("left", "bottom")))
grid.draw(lgd)
