The dygraphs package is an R interface to the dygraphs JavaScript charting library. It provides rich facilities for charting time-series data in R, including:

• Automatically plots xts time series objects (or any object convertible to xts).
• Highly configurable axis and series display (including optional second Y-axis).
• Rich interactive features including zoom/pan and series/point highlighting.
• Display upper/lower bars (e.g. prediction intervals) around series.
• Various graph overlays including shaded regions, event lines, and point annotations.
• Use at the R console just like conventional R plots (via RStudio Viewer).
• Seamless embedding within R Markdown documents and Shiny web applications.
