In JohnCoene/echarts: EChart htmlwidget

Description

Add line serie.

Usage

eline(p, serie, name = NULL, stack = NULL, clickable = TRUE,
  xAxisIndex = 0, yAxisIndex = 0, symbol = NULL, symbolSize = "2 | 4",
  symbolRotate = NULL, showAllSymbol = FALSE, smooth = TRUE,
  legendHoverLink = TRUE, dataFilter = "nearest", z = 2, zlevel = 0,
  tooltip, ...)

eline_(p, serie, name = NULL, stack = NULL, clickable = TRUE,
  xAxisIndex = 0, yAxisIndex = 0, symbol = NULL, symbolSize = "4",
  symbolRotate = NULL, showAllSymbol = FALSE, smooth = TRUE,
  legendHoverLink = TRUE, dataFilter = "nearest", z = 2, zlevel = 0,
  tooltip, ...)

Arguments

p	an echart object.
serie	value column name to plot.
name	of serie.
stack	name of the stack.
clickable	whether plot is clickable.
xAxisIndex, yAxisIndex	axis indexes.
symbol	symbol for point marker, see details for valid values.
symbolSize	of symbol.
symbolRotate	angle by which symbol is rotated, i.e.: 30.
showAllSymbol	By default, a symbol will show only when its corresponding axis label does.
smooth	whether to smooth line.
legendHoverLink	enables legend hover link to the chart.
dataFilter	ECharts data filtering strategy, see details.
z, zlevel	first and second grade cascading control, the higher z the closer to the top.
tooltip	style of tooltip.
...	any other argument to pass to the serie.

Details

Valid values for symbol:

• circle

• rectangle

• triangle

• diamond

• emptyCircle

• emptyRectangle

• emptyTriangle

• emptyDiamond

• heart

• droplet

• pin

• arrow

• star

dataFilter: ECharts will optimize for the situation when data number is much larger than viewport width. It will filter the data showed in one pixel width. And this option is for data filtering strategy.

## Not run: 
df <- data.frame(x = 1:50, y = runif(50, 5, 10), z = runif(50, 7, 12), w = runif(50, 10, 13))

df %>%
  echart(x) %>%
  eline(y) %>%
  eline(z)

# JS sizing function
sizing <- htmlwidgets::JS("function(value){ return value[1]/1.5}")

df %>%
  echart_("x") %>%
  eline_("y", "w",
         symbolSize = sizing,
         showAllSymbol = TRUE,
         symbol = "emptyCircle") %>%
  etooltip() %>%
  etheme("helianthus")

df %>%
  echart_("x") %>%
  eline_("y", stack = "grp") %>%
  eline_("z", stack = "grp", symbol = "emptyDroplet", showAllSymbol = TRUE, symbolSize = 5) %>%
  eline_("w", showAllSymbol = TRUE, symbolSize = 4, symbol = "emptyHeart", stack = "grp2") %>%
  etooltip() %>%
  elegend() %>%
  etoolbox_magic(type = list("line", "bar"))
