FEATURE ADDED:
Legend can now show change of the value/percents comparing to the previous date. Previously you could only show the change comparing to the first value of the selected period.

If you want to show percent change of a value comparing to a previous value, use:
{close.percents.single}

If you want to show value change comparing with previous value, use:
{close.change.single}

• coordinateToValue(coordinate) method added to ValueAxis. Converts coordinate (pixels) to value.
• recalculateToPercents property added to valueAxis. If you set it to true, values will be recalculated to percents, using first selected data items value as base value. To show percent values in balloons or legend, use [[percents.value]], [[percents.close]] tags. There is a checkbox “racalculate to percents” in candlestick example. Check it to see this feature in action.
• graphs can have a different dataProviders from main chart’s data provider. Note: only categories available in chart’s dataProvider will be visible.
• zoomToValues(startValue, endValue) method added to ValueAxis. It can only be used with XY chart.
• When zooming XY chart, value axes dispatch axisZoomed event, with startValue and endValue properties.
• invalidateData() method added to AmChart.

Some minor bugs were fixed.

Quick Charts motto is: Ease of Use, Speed, Small Footprint. It is amCharts Bundle’s little brother. It has less features, but concentrates on what’s important for the majority of users. In order to achieve this we didn’t just strip the features off of amCharts Bundle, but created Quick Charts from scratch.

Current release supports line and column charts only. Support for other chart types coming soon.

We’re extremely happy to announce a new addition to our offerings – Premium Map Pack. It is a result of months of scrupulous work. There are two main aspects that set maps from the new pack apart:

1. Increased level of detail. We took extreme care of making those maps as accurate and as detailed as possible. Coastlines, pennisulas, fjords, borders, are now presented in greater detail and accuracy.
2. Number of countries. World map now includes even more countries, territories and even tiny island nations. All in all 252 areas are represented!

Current version of the Premium Map Pack includes four maps:

• World
• World with Antarctica
• World in Continents
• Europe

We will be adding the rest of the continens over the course of the coming weeks and possibly even other interesting maps in the future.

Check out a couple of sample strips from the Premium World map: Europe and America.

Availability

As a thank you for our commercial license buyers we’re releasing Premium Map Pack as a free download for them. So if you own any amMap 2 license (including single-site) just head to our customers’ download area. (use your email you entered when ordering amMap and order reference id to login).

If you do not own a commercial license, now would be a perfect time to acquire one. The licenses start at 85EUR.

UPDATE: Premium Map Pack 2.1 now includes all main continents (North and South Americas, Europe, Asia, Africa, Oceania) plus several logical groups (Central America, Middle East, Caribbean)

Upgrading from previous version

The new chart types caused some changes in the structure, so there will be several things you’ll need to do when migrating from previous versions. We are sorry for this inconvenience but we feel it is the absolutely necessary change for the sake of consistency in all future versions.

1. AmCartesianChart class renamed to AmSerialChart – simply change the name in your applications.

2. “cartesian” folder with classes like AmGraph, ChartScrollbar, ChartCursor changed to “chartClasses” – if you import one of these classes in your Actionscript, you should change the path to the class.

3. AmChart, AmBalloon, AmLegend classes were moved from com.amcharts to com.amcharts.chartClasses. Change the paths to these classes too.

4. Even if you do not use these classes in your ActionScript, but only mxml, Flex builder can cache the old paths to these classes and show errors when compiling application. The most easy way to solve this is to remove all your amChart objects from the application, save it and bring it back exactly as it was. Now the application should compile properly.

5. CartesianChartEvent is renamed to SerialChartEvent.

6. PieChartEvent and SerialChartEvent (previously CartesianChartEvent) do not have dataUpdated event type anymore. dataUpdated event is now AmChartEvent’s type.

The final version of Flex components will be released on February 8. We do not plan adding new features during this time. The structure won’t change again.

• FEATURE: new <movie> attribute: active [true] (true/false)
  If set to "false" the movie will be invisible to mouse events (hover, click, etc.) even if behavior associated with it is set – the mouse will rather interact with underlying map. This feature will allow you to create map overlays that do not interfear with the map functionality.
• FEATURE: you can now instruct amMap to preserve the original color of the area like it is set in the map SWF. Set <area><preserve_color> to "true" if you want to preserve color of all the areas. To preserve the color for individual areas you can set "preserve_color" attribute in the <area> tag in your data.
• FEATURE: lines can now display rollover balloon. 

  Additional parameters for <line> data tag: 

  - balloon [true] (true/flase): whether to display balloon on rollover or not. 
  - title [text] (): line title

  Additional related settings: 

  - <line><balloon_text> [] ({title}): You can set any text here. Special code {title} will be replaced with whatever there is in <line>’s "title" attribute.

• FEATURE: new setting <hover_focus>: 
  <movie><hover_focus> [false] (true/false)
  <line><hover_focus> [false] (true/false)
  <label><hover_focus> [false] (true/false) 

  If set to true hovered movie/line/label will be brought in front of other movies/lines/labels.

• FEATURE: new setting <area><color_no_value> [] (color hex code)
  If set all areas that do not have value attribute will be painted in this color. But only if other overriding color options are not set. I.e. color attribute in <area>, or <preserve_color> setting.
• TWEAK: amMap now supports areas with negative values correctly.
• BUG FIX: map enlargement was not functioning properly with redraw=true, again :)
• BUG FIX: setData and timeline slide transitions were leaving some leftover area data if some areas were missing in the new data. This is now corrected with one downside: you have to have <color_unlisted> set in your settings file, because otherwise the area will be left colored the way it was before setData/slide.
• NEW MAP: Costa Rica

• A new setting <balloon_text> was added to <data_set_selector> group. Sometimes data set title doesn’t fit in the drop-down. If you set a value like {title} here, the roll-over balloon will display full title so users can read it. You can also display {short} title and a {description} in this balloon.
• A new setting, <disable_custom_cursors> was added. If you set it to true, custom hand and resize arrow cursors will be disabled.
• A new setting, <chart><events><show_date> was added. If you set it to false, the date will not be displayed in the balloon (when you roll-over the event bullet)
• When user clicks on a predefined period button, this JavaScript function is called: amPeriodSelected(chart_id, type, count, id);
• Now you can select predefined period with this JavaScript function:

  flashMovie.selectPeriod(id);

  id is the pid attribute: <period type="DD" count="10" pid="p1">10D</period> or order number of your period if you don’t have pid attribute.

• amClickedOn and amRolledOver JavaScript functions now return Array of objects containing data set title, short title, id and values of a clicked date:

  amClickedOn(chart_id, date, period, data_object)

  data_object’s structure:

  a) when data is not grouped into longer periods:
      values:
        volume:
          close: 21010110
      id: 0
      short: ES
      title: East Stock

  b) when data is grouped into longer periods:
      values:
        volume:
          close: 16344710
          high: 21587410
          low: 16344710
          sum: 90934150
          open: 16509710
      id: 1
      short: ES
      title: East Stock

• FIX:In some cases event bullets were incorrectly placed above the graph.
