The gvisMotionChart function reads a data.frame and creates text output referring to the Google Visualisation API, which can be included into a web page, or as a stand-alone page. The actual chart is rendered by the web browser in Flash. A motion chart is a dynamic chart to explore several indicators over time.
gvisMotionChart( data, idvar = "id", timevar = "time", xvar = "", yvar = "", colorvar = "", sizevar = "", date.format = "%Y/%m/%d", options = list(), chartid )

column name of data that identifies bubbles in the
same series. Use the same value to identify all bubbles that belong
to the same series; bubbles in the same series will be assigned the
same color. Series can be configured using the |

list of configuration options for Google Motion Chart. The options are documented in detail by Google online: \Sexpr[results=rd]{gsub("CHARTNAME", googleChartName, readLines(file.path(".", "inst", "mansections", "GoogleChartToolsURLConfigOptions.txt")))} \Sexpr[results=rd]{paste(readLines(file.path(".", "inst", "mansections", "gvisOptions.txt")))} |
chartid |
character. If missing (default) a random chart id will be
generated based on chart type and |
returns list
of class
\Sexpr[results=rd]{paste(readLines(file.path(".", "inst",
"mansections", "gvisOutputStructure.txt")))}
Because of Flash security settings the chart might not work correctly when accessed from a file location in the browser (e.g., file:///c:/webhost/myhost/myviz.html) rather than from a web server URL (e.g. https://www.myhost.com/myviz.html). See the googleVis package vignette and the Macromedia web site (https://www.macromedia.com/support/documentation/en/flashplayer/help/) for more details.
Please note that a timevar
with values less than 100 will
be shown as years 19xx.
