In rtsplot: Time Series Plot

Plot time series with second Y axis

Description

Detailed discussion for validity of dual Y axis at [Dual axes time series plots may be ok sometimes after all](http://freerangestats.info/blog/2016/08/18/dualaxes)

Usage

rtsplot2Y(y, las = 1, type = "l", col.axis = "red", ylim = NULL, log = "", ...)

Arguments

y	xts object
las	rotation of Y axis labels, defaults to 1, for more info see par
type	plot type, defaults to 'l', for more info see plot also support 'ohlc', 'hl', 'candle', 'volume' types
col.axis	axis color, defaults to 'red'
ylim	range on Y values, defaults to NULL
log	log scale x, y, xy axes, defaults to ”
...	additional parameters to the plot

Value

nothing

Examples

# generate time series data
y = rtsplot.fake.stock.data(1000)
symbol = 'SPY'

y1 = rtsplot.fake.stock.data(1000, 100)
symbol = 'IBM'
	
 # two Y axis example
 # to plot second Y axis, free some space on left side, set LeftMargin=3
 layout(1)
 cols = c('black', 'red')

 rtsplot(y, type = 'l', LeftMargin=3, col=cols[1])
			
 rtsplot2Y(y1, type='l', las=1, col=cols[2], col.axis=cols[2])

 rtsplot.legend('SPY(rhs),IBM(lhs)', cols, list(y,y1))
