Annotation charts and histograms with googleVis
After my posts on timeline, Sankey and calendar charts, this will be the last to introduce new chart types of the developer version of googleVis. Today I will give examples for the new annotation charts and histograms.
Annotation 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 (
gvisAnnotatedTimeLine in 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.
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.
