# January 2012 release notes

The January 2012 release of OfficeExcel is now available and has these changes:

- Relevant charts libraries now have two new properties:
  - chart.events.click
  - chart.events.mousemove
  These new properties make it much easier to add your own event listening functions. You can read more about these new properties here.
- The Radar chart origin is now the "north" axis instead of the "east" axis.
- The Radar chart now supports a stacked variant when all datasets have the same number of data points.
- Implemented the Wave2 animation, which uses the requestAnimationFrame() function. In some browsers the difference is quite subtle.
- In some charts, there is now a getValue() method which can be used in event listener functions to get the appropriate value (if any) when the chart is clicked for example. This affects the Bar, HBar, HProgress, Line, Scatter, Thermometer and VProgress charts.
- Added a getBar() method to the Thermometer which can be used inside standard event listener functions (not the OfficeExcel ones) to determine if the bar area was clicked (or mouseover'ed etc).
- Added Rose chart Explode/Implode animation effects.
- Added Radar chart chart.radius property.
- Radar chart labels have been altered so that their placement is now not linked to the number of points on the chart. They also now go around the edge of the chart.
- A Grow effect has been added for the Gantt chart.
- The Gantt chart now has a chart.tooltips.event property.
- Added the Gantt chart property chart.labels.align
- The Gantt chart background grid autofit option now defaults to true (ie enabled).
- Added new background image properties:
  - chart.background.image.stretch
  - chart.background.image.x
  - chart.background.image.y
  - chart.background.image.align
  These are relevant to the Bar, Line and Scatter charts.
- Added new HOWTO guides for certain common tasks.
- Added a new Conceal effect - the opposite of the Reveal effect.
- Added new properties to the Gauge chart:
  - chart.centerpin.radius
  - chart.tickmarks.small
  - chart.tickmarks.big
  - chart.title.top
  - chart.title.top.font
  - chart.title.top.size
  - chart.title.top.color
  - chart.title.top.bold
  - chart.title.bottom
  - chart.title.bottom.font
  - chart.title.bottom.size
  - chart.title.bottom.color
  - chart.title.bottom.bold
- The two scale properties chart.scale.point and chart.scale.thousand have been synchronised across the majority of chart libraries.
