geom_step {ggplot2} | R Documentation |
Connect observations by stairs
geom_step(mapping=NULL, data=NULL, stat="identity", position="identity", direction="hv", ...)
mapping |
mapping between variables and aesthetics generated by aes |
data |
dataset used in this layer, if not specified uses plot dataset |
stat |
statistic used by this layer |
position |
position adjustment used by this layer |
direction |
direction of stairs: 'vh' for vertical then horizontal, or 'hv' for horizontal then vertical |
... |
other arguments |
Equivalent to plot(type='s').This page describes geom_step, see layer
and qplot
for how to create a complete plot from individual components.
A layer
The following aesthetics can be used with geom_step. Aesthetics are mapped to variables in the data with the aes
function: geom\_step(\code{aes}(x = var))
colour
: border colour
size
: size
linetype
: line type
