issue.
googleVis 0.5.5
Added example to gvisMerge help file.
README.md when converted to (X)HTML using a current version of
pandoc showed minor problems when validated using W3C Markup
Validator.
In some case when no xvar and yvar arguments where provided for core
charts the output wasn’t sensible. This bug was introduced with version
0.5.3. Thanks to stanstrup for reporting this issue.
googleVis 0.5.4
Tidying up of googleVis demo, vignette and README file
googleVis 0.5.3
Default chart width is set to ‘automatic’ instead of 500
pixels.
Intervals for columns roles have to end with the suffix “.i”, with i
being an integer. Several interval columns are allowed, see the Roles
demo and vignette for more details.
The order of y-variables in core charts wasn’t maintained. Thanks to
John Taveras for reporting this bug.
Width and height of googleVis charts were only accepted in pixels,
although the Google Charts API uses standard HTML units (for example,
‘100px’, ‘80em’, ‘60’, ‘automatic’). If no units are specified the
number is assumed to be pixels. This has been fixed. Thanks to Paul
Murrell for reporting this issue.
googleVis 0.5.2
Fixed minor formatting issues in documentation and vignettes.
Added examples in demo googleVis to show how to customize points and
lines and to the help files of gvisLineChart and gvisScatterChart.

Scatter-, Bar-, Column-, and Line Charts.
New demo Roles showing how different column roles can be used in
core charts to highlight data.
New vignettes written in R Markdown showcasing googleVis examples
and how the package works with knitr.
The help files of gvis charts no longer show all their options,
instead a link to the online Google API documentation is given.
Updated googleVis demo
All googleVis output will be displayed in your default browser. In
previous versions of googleVis output could also be displayed in the
preview pane of RStudio. This feature is no longer available with the
current version of RStudio, but is likely to
be introduced again with the release of RStudio version 0.99 or
higher.
googleVis 0.4.7
New option ‘googleVis.viewer’ which controls the default output of
the googleVis plot method. On package load it is set to
getOption(“viewer”). It you use RStudio, then its viewer pane will be
used for displaying non-Flash charts. Set
options(“googleVis.viewer”=NULL) and the googleVis plot function will
open all output in the default browser again.
The package start-up message makes the user aware of the default
viewer option.
Added example to gvisMap that illustrates how the icon can be
changed.
googleVis 0.4.6
googleVis will use the Viewer pane in RStudio (version >=
0.98.441) to display non-Flash charts by default. The setting is
controlled via the option viewer. Set options(“viewer”=NULL) and the
googleVis plot function will open all output in the default browser
again.
googleVis 0.4.5
The indentation of some of the HTML output changed in version 0.4.4,
which as a result stopped googleVis output to be rendered with
knitr.
googleVis 0.4.4
gvisTable() gained new parameter formats, which allow users to
specify the format of numbers displayed in a table. Thanks to Jacqueline
Buros for providing ideas and code.
Doughnut charts are now possible as pie charts with a hole.
New examples for gvisBarChart, gvisColumnChart, gvisComboChart
demonstrating how to change the width of bars
Extended FAQ section
googleVis 0.4.3
givsGeoChart has a new argument ‘hovervar’ to specify a column in
input data that can be used to show additional information in a geo
chart. See the new example of plotting countries’ credit rating in the
help file for a use case. Thanks to John Muschelli for suggesting this
feature.
googleVis 0.4.2
The core charts (e.g. line, area, bar, column and combo charts)
accept now also date variables for the x-axis. Thanks to Sebastian
Campbell for pointing this out.
The WorldBank demo uses now the WDI package. Thanks to John
Maindonald for providing the code.
Fixed typos in Stock and Andrew example data. Thanks to Sebastian
Campbell for reporting this issue.
googleVis 0.4.0
New function renderGvis to support shiny. This function allows user
to insert googleVis output into shiny apps, similar to renderText and
renderPlot. See the help page for more details. Many thanks to Joe Cheng
for his support and help.
In order to support shiny the order of the elements of the
gvis*()\(html\)chart vector changed.
The positions of jsChart and jsFooter have been swapped.
The load mechanism for the Google API changed from http to https
again. Thanks to Jacques Philip.
The package dependencies changed to imports statements in
DESCRIPTION. Thanks to Suraj Gupta for pointing this out.
The R.rsp example in demo googleVis has been moved into its own demo
Rrsp.
A FAQ and shiny section has been added to the vignette.
jsDisplayChart didn’t check if the google visualization function is
already loaded. Many thanks to Mark Melling for reporting the issue and
providing a solution.
The demo WorldBank didn’t download all data but only the first 12000
records. Many thanks to John Maindonald reported this issue.
googleVis 0.3.3
Clarified the usage of the argument state in the help file of
gvisMotionChart. Thanks to Leonardo Trabuco
googleVis 0.3.3
plot.gvis didn’t open a browser window when options(gvis.plot.tag)
was not set to NULL, but the user explicitly called plot.gvis with tag
NULL. Thanks to Sebastian Kranz for reporting this bug.
googleVis 0.3.2
plot.gvis gained the argument ‘tag’, which works similar to the
argument of the same name in print.gvis. By default the tag argument is
NULL and plot.gvis has the same behaviour as in the previous versions of
googleVis. However, the argument can be set outside plot.gvis via
options(gvis.plot.tag=…). This allows users to switch plot statements
into print statements by changing only one setting. This is particular
useful when googleVis is used in combination with knitr or R.rsp.
Setting options(plot.gvis.tag=“chart”) will ensure that plot(gvisOutput)
statements will be included into the final HTML output. See the help
file to plot.gvis and vignette for more details.
The tag argument of print.gvis can be set globally from outside the
function via options(gvis.print.tag)
The vignette has a new section describing how to set the behaviour
of plot.gvis and print.gvis via options(gvis.plot.tag),
options(gvis.print.tag) respectively. The section describing how
googleVis can be used with knitr has been extended and an additional
example included.
plot.gvis can open any html file now, not just gvis-objects. Like
with gvis-object it will copy the file into a temporary directory and
display it via the R HTTP server.
googleVis 0.3.1
The argument ‘browser’ introduced in version 0.3.0 has been removed
again. The argument was set by default to the output of
getOptions(‘browser’), if interactive() returned TRUE, otherwise to
‘false’. The function getOptions(‘browser’) returns either a string or a
function call. The later caused an error message, as experienced with
RStudio and RGui.exe. The check is now handled internally by plot.gvis.
Thanks to Sebastian Kranz for reporting this bug.
googleVis 0.3.0
plot.gvis has a new argument ‘browser’. The argument is passed on to
the function browseURL. The ‘browser’ argument is by default set based
on the output of interactive(). This prevents R CMD CHECK trying to open
browser windows during the package checking process. See the help file
of plot.gvis for more details. Thanks to Henrik Bengtsson for his
comments and suggestions.
gvisMotionChart has new arguments xvar, yvar, colorvar and sizevar.
Those arguments are optional and set the various dimensions of a motion
chart, similar to those in gvisBubbleChart. Thanks to Sebastian Kranz
for the idea and initial code.
gvisGeoChart accepts tooltip.triggers following an update of the
Visualisation API by Google, 24 September 2012
R data frames are transformed into JSON objects using a new function
provided by Sebastian Kranz and Wei Luo. The new function speeds up the
googleVis functions.
Changed the load mechanism for the Google API from http to https.
Thanks to Erik Bülow for pointing this out (Issue 19).
Changed example in help file of gvisMap to show how to include html
code in tooltip.

22 February 2012.
Moved vignette from folder /inst/doc to /vignettes
Quoted from Google
https://developers.google.com/chart/interactive/docs/release_notes?csw=1:
Added gradient color mode to bubble chart.
Geo chart:
Region interactivity in marker mode is now disabled by default. How
to keep the old behavior? Set the enableRegionInteractivity option to
true.
Markers are now opaque by default. How to keep the old behaviour?
Set the markerOpacity option to 0.5.
Marker size is now between 3 and 12 pixels by default. How to keep
the old behavior? Set the sizeAxis option to {minSize: 2, maxSize:
30}.
A magnifying glass is now opened when the user hovers over cluttered
markers (excluding IE<=8). How to keep the old behaviour? Set the
magnifyingGlass option to {enable: false}.
Maps are not stretched by default anymore, but rather kept at the
original aspect ratio. How to keep the old behavior? Set the
keepAspectRatio option to false.
googleVis 0.2.14
Updated help files to be in line with the Google Visualisation API
pages
Updated vignette with new section on dealing with apostrophes in
column names and updated example in section “Setting options”

The way RJSONIO treats backslashes changed in version 0.7.1 and as a
result some Google charts were no longer displayed.
googleVis 0.2.4
plot.gvis no longer writes into the package folder. Instead
temporary files are created. This overcomes the need to install the
package into a directory with write access. Many thanks to Ben Bolker
for this suggestion and code contribution.
plot.gvis no longer requires the web server provided by the R.rsp
package to display the visualisation output. Instead it uses the
internal R HTTP help server. Many thanks to John Verzani for this
suggestion and code contribution.
