Plotting

TimeSeries defines a recipe that allows plotting to a number of different plotting packages using the Plots.jl framework (no plotting packages will be automatically installed by TimeSeries).

Here we use the data from Yahoo Fiance as a demo.

Plotting as multiple series

The recipe allows TimeArray objects to be passed as input to plot. The recipe will plot each variable as an individual line, aligning all variables to the same y axis. backend).

Plotting candlestick

We have seriestype = :candlestick support that requires four columns exist in the input. They are open, high, low and close (case-insensitive).
