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’).

  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.
• Chart editor was not validated properly under XHMTL 1.0 Strict

googleVis 0.2.17

• Added sections with information to ‘knitr’ and ‘Rook’ to vignette
• Added example to gvisMerge demonstrating the use of ‘Reduce’
• Data frames with one row only were not displayed in a chart. Thanks to Oliver Jay and Wai Tung Ho for reporting this issue.
• Fixed earth quake example, using data from https://ds.iris.edu/seismon/eventlist/index.phtml, Mag was read as factor rather than numeric

googleVis 0.2.16

• Updated example in help file of gvisGeoChart for individual colour axis
• Updated links to Google API pages
• gvisMotionCharts accepts quarterly and weekly time dimensions. Thanks to Jason Pickering for providing a patch.

googleVis 0.2.15

• 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.
