Trelliscope options

facet_trelliscope() and trelliscope() provide several options for handling the display output:

The directory in which to store the display
Storing multiple displays in the same directory
Providing more detailed descriptions of the display
The plot aspect ratio
Specifying the default viewer state

Specifying the output directory

trelliscope(dat, path = "...", ...)

ggplot(...) +
  ... +
  facet_trelliscope(path = "...", ...)

trelliscope(by_symbol,
  name = "candlestick_top500",
  desc = "Candlestick plot of the 500 most-traded NASDAQ stocks in 2016",
  md_desc = "
## Candlestick Plot
A [candlestick plot](https://en.wikipedia.org/wiki/Candlestick_chart)
is a financial plot...
..." )

Plot aspect ratio

trelliscope(dat, width = 600, height = 300, ...)

ggplot(...) +
  ... +
  facet_trelliscope(width = 600, height = 300, ...)

Default viewer state

trelliscope(dat, state = ..., ...)

ggplot(...) +
  ... +
  facet_trelliscope(state = ..., ...)

Let's practice!
