TimeSeriesPlot(FitAR) | R Documentation |
Cleveland pointed out that the aspect-ratio is important in graphically showing the rate-of-change or shape information. For many time series, it is preferably to set this ratio to 0.25 than the default. In general, Cleveland shows that the best choice of aspect-ratio is often obtained by if the average apparent absolute slope in the graph is about 45 deg. But for many stationary time series, this would result in an aspect-ratio which would be too small. As a comprise we have chosen a default of 0.25 but the user can select other choices.
TimeSeriesPlot(z, SubLength = 200, aspect = 0.25, type="l", ylab=NULL, main=NULL, ...)
z |
ts object or vector, time series data |
SubLength |
maximum number of data points per panel |
aspect |
optional setting for the aspect-ratio |
type |
plot type, default type="l" join points with lines |
ylab |
optional label for vertical axis |
main |
optional title |
... |
optional arguments passed to xyplot |
If z has attribute "title" containing a character string, this is used
on the plot.
Time series input using the function Readts
always
have this attribute set.
