plot_dts: Plot data.table time series

Description

Plot data.table time series

plot_dts

Add data to be plotted.

$lines

Add lines with following arguments:

`names`	vector of column names to plot
`labels`	vector of labels if different from column names
`type`	vector or single value, see lines
`lty,pch,col,lwd,lend`	vector or single value, see par
`bg`	vector or single value, see points

$candles

Add candles with following arguments:

`ohlc`	vector of open, high, low and close names
`timeframe`	candle timeframe in minutes for intraday candles
`position`	relative to time position only `'end'` supported
`type`	`'barchart'` or `'candlestick'`
`gap`	gap between candles in fraction of `width`
`mono`	should all candles have same color?
`col,col_up,col_flat,col_down`	colors

$limits

`xlim`	vector of length two to limit plot area horizontally
`ylim`	vector of length two to limit plot area vertically
`tlim`	date or time vector of length two
`time_range`	intraday time limit in format 'H:M:S/H:M:S'

$style

Change default plot options. Available options are:

`grid`
`minute`	`list(col,lty)`	minute vertical gridline color and line type
`hour`	`list(col,lty)`	hour vertical gridline color and line type

`zero`	`list(col,lty)`	zero horizontal gridline color and line type
`time`
`grid`	`logical`	should vertical gridlines be plotted?
`resolution`	`character`	auto, minute, hour, day, month, year or years

`candle`
`auto`	`logical`	shoud candles be automatically detected and plotted?
`col`	`list(mono,up,flat,down)`	colors
`gap`	`numeric`	gap between candles in fraction of `width`
`mono`	`logical`	should all candles have same color?
`position`	`character`	relative to time position only `'end'` supported
`type`	`character`	`'candlestick'` or `'barchart'`
`line`
`auto`	`logical`	shoud lines be automatically detected and plotted?
`legend`
`col`	`list(background,frame)`	colors
