Error bars

Description

Custom series to display error-bars for scatter,bar or line series

Usage

ecr.ebars(wt, df = NULL, hwidth = 6, ...)

Arguments

wt	A widget to add error bars to, see createWidget
df	NULL(default) or data.frame with four or more columns ordered exactly (x,y,low,high,others). When NULL, data is taken from wt's dataset where order should be the same (x,y,low,high,etc)
hwidth	Half-width of error bar in pixels, default is 6.
...	More parameters for custom serie

Details

ecr.ebars are custom series, so ec.init(load='custom') is required.
Grouped series are supported, but require the group column to be included in df.
Will add a chart legend and its own tooltip if none is provided.
ecr.ebars with name attribute will show separate in the legend.
Command should be called last, after all other series.

Value

A widget with error bars added if successful, otherwise the input wt

Examples

if (interactive()) {
tmp <- round(rnorm(24, sin(1:24/2)*10, .5))
df <- data.frame(x = 1:24, val = tmp, 
                 lower = round(rnorm(24, tmp -10, .5)),
                 upper = round(rnorm(24, tmp + 5, .8))
)
p <- df |> ec.init(load='custom') |> ecr.ebars()
p$x$opts$tooltip <- list(show=TRUE)
p
}
