Description

tooltips can be displayed when mouse is over segments, on click actions can be set with javascript instructions.

Usage

geom_segment_interactive(mapping = NULL, data = NULL, stat = "identity", position = "identity", arrow = NULL, lineend = "butt", na.rm = FALSE, show.legend = NA, inherit.aes = TRUE, ...)

Arguments

mapping

The aesthetic mapping, see geom_point.

data

# add interactive segments to a ggplot -------
counts <- as.data.frame(table(x = rpois(100,5)))
counts$x <- as.numeric( as.character(counts$x) )
counts$xlab <- paste0("bar",as.character(counts$x) )

gg_segment_1 <- ggplot(data = counts, aes(x = x, y = Freq,
			yend = 0, xend = x, tooltip = xlab ) ) +
	geom_segment_interactive( size = I(10))

dataset = data.frame(x=c(1,2,5,6,8),
		y=c(3,6,2,8,7),
		vx=c(1,1.5,0.8,0.5,1.3),
		vy=c(0.2,1.3,1.7,0.8,1.4),
		labs = paste0("Lab", 1:5))
dataset$clickjs = paste0("alert(\"",dataset$labs, "\")" )

gg_segment_2 = ggplot() +
	geom_segment_interactive(data=dataset, mapping=aes(x=x, y=y,
			xend=x+vx, yend=y+vy, tooltip = labs, onclick=clickjs ),
