Annotation chartsAnnotation charts have been part of the Google Chart tools for a long time and googleVis as well. However, in the past only a flash based version was available (
gvisAnnotatedTimeLinein googleVis). With the new Google Charts Tools version also a HTML5 version was released. In googleVis it is integrated as
gvisAnnotationChart. It works in exactly the same way as the Flash based version, so here is an example.
For the R code below to run you will require the developer version (≥ 0.5.0-4) of googleVis from GitHub and R ≥ 3.0.2.
HistogramsHistograms are a new chart type in Google Chart Tools API - not so in R. Still, it is nice to know that one can create those now as well.
For more information and installation instructions see the googleVis project site and Google documentation.
