pv.area: Add a bar to the visualization.

In leeper/rwebvis: Create graphics for the web from R.

Description

Add a bar to the visualization.

Usage

pv.area(bottom=0, height.name="y", left.name="x", height.scale=paste("linear", height.name, "y", sep = "."), left.scale=paste("linear", left.name, "x", sep =
    "."), scale.min=0, ...)

Arguments

height.name	The name of the field in the supplied data frame or vector.
left.name	The name of the field in the supplied data frame or vector.
height.scale	The scale of the field in the supplied data frame or vector.
left.scale	The scale of the field in the supplied data frame or vector.
bottom	The distance from the bottom of the panel.
scale.min	The minimum value for the y-axis scale.
...	The parameters from pv.chart

# line example 1 (using layers)
wv <- pv.panel(width=150, height=150)
render.webvis(wv + pv.area(wv=wv, data=c(1, 1.2, 1.7, 1.5, .7, .5, .2), bottom=0, height.name="y", left.name="x", height.scale="linear.y.y", left.scale="linear.x.x"))

wv <- pv.panel(width=150, height=150)
render.webvis(wv + pv.area(wv=wv, data=c(1, 1.2, 1.7, 1.5, .7, .5, .2)))

# line example 2 (need to make sure that it doesn't go over the edge
wv <- pv.panel(width=150, height=150)
wv <- wv + (pv.area(wv=wv, data=c(1, 1.2, 1.7, 1.5, .7, .5, .2), height.name="y", left.name="x", height.scale="linear.y.y", left.scale="linear.x.x"))
render.webvis(wv)

# line example 4

# line example 5
