gvisMotionChart(data, idvar = "id", timevar = "time", xvar = "",
yvar = "", colorvar = "", sizevar = "",
date.format = "\%Y/\%m/\%d", options = list(), chartid)
}
\arguments{
\item{data}{a \code{data.frame}. The data has to have at least four
columns with subject name (\code{idvar}), time (\code{timevar}) and
two columns of numeric values. Further columns, numeric and
character/factor are optional. The combination of \code{idvar} and
\code{timevar} has to describe a unique row. The column names of the
\code{idvar} and \code{timevar} have to be specified. Further
columns, if not specified by the other arguments (\code{xvar, yvar,
colorvar, sizevar}), will be assumed to be in the order of the
arguments.}
\item{idvar}{column name of \code{data} with the subject to be
analysed.}
\item{timevar}{column name of \code{data} which shows the time
dimension. The information has to be either numeric, of class
\code{\link{Date}} or a character which follows the pattern
'YYYYWww' (e.g. '2010W04' for weekly data) or 'YYYYQq'
(e.g. '2010Q1' for quarterly data).}
\item{xvar}{column name of a numerical vector in \code{data} to be
plotted on the x-axis.}
\item{yvar}{column name of a numerical vector in \code{data} to be
plotted on the y-axis.}
\item{colorvar}{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 \code{series} option.}
\item{sizevar}{values in this column are mapped to actual pixel
values using the \code{sizeAxis} option.}
\item{date.format}{if \code{timevar} is of class \code{\link{Date}}
then this argument specifies how the dates are reformatted to be
used by JavaScript.}
\item{options}{list of configuration options for Google Motion Chart.
The options are documented in detail by Google online:
% START DYNAMIC CONTENT
\Sexpr[results=rd]{gsub("CHARTNAME",
googleChartName,
readLines(file.path(".", "inst", "mansections",
"GoogleChartToolsURLConfigOptions.txt")))}
\Sexpr[results=rd]{paste(readLines(file.path(".", "inst",
"mansections", "gvisOptions.txt")))}}
\item{chartid}{character. If missing (default) a random chart id will be
generated based on chart type and \code{\link{tempfile}}}
}
\value{
\Sexpr[results=rd]{paste(gvisChartName)} returns list
of \code{\link{class}}
\Sexpr[results=rd]{paste(readLines(file.path(".", "inst",
"mansections", "gvisOutputStructure.txt")))}
}
\description{
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.
}
\section{Warnings}{
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 (\url{https://www.macromedia.com/support/documentation/en/flashplayer/help/})
for more details.
}
\section{Note}{
Please note that a \code{timevar} with values less than 100 will
be shown as years 19xx.
}
\examples{
## Please note that by default the googleVis plot command
## will open a browser window and requires Flash and Internet
## connection to display the visualisation.
M1 <- gvisMotionChart(Fruits, idvar="Fruit", timevar="Year")
plot(M1)
\dontrun{
## Usage of date variable
M2 <- gvisMotionChart(Fruits, idvar="Fruit", timevar="Date",
date.format = "\\\%Y\\\%m\\\%d")
plot(M2)
## Display weekly data:
M3 <- gvisMotionChart(Fruits, "Fruit", "Date", date.format="\\\%YW\\\%W")
plot(M3)
}
## Options: no side panel on the right
M4 <- gvisMotionChart(Fruits,"Fruit", "Year",
options=list(showSidePanel=FALSE))
plot(M4)
## Options: trails un-ticked
M5 <- gvisMotionChart(Fruits, "Fruit", "Year",
options=list(state='{"showTrails":false};'))
plot(M5)
## You can change some of displaying settings via the browser,
## e.g. the level of opacity of non-selected items, or the chart type.
## The state string from the 'Advanced' tab can be used to set those
## settings via R. Just copy and past the string from the browser into
## the argument state of the options list.
## Here is an example of a motion chart, with an initial line chart
## displayed. Ensure that you have a newline at the start and end of
## your settings string.
