FEATURES ADDED:

• Columns can now have rounded corners – thanks to the new setting for <graph>:<corner_radius>.
  You can set corner radius in pixels or in percents. For example, 100%. (However from usability side we don’t recommend doing this).
• The chart can display balloon with data set’s title when user rolls-over the legend item. This is convenient when you have short data set name in the legend and want to see the full name on roll-over. To enable this feature, set <chart><legend><show_balloon> to true.
• Possibility to set <bg_alpha> (background opacity) for period_selector buttons.
• An additional parameter is passed to amGetZoom function – period. It tells which period is currently used (if the chart groups data). So now the the chart calls this function and passes: amGetZoom(chart_id, from, to, period).
• amReturnParam function also returns the param name: amReturnParam(chart_id, value, param);

amCharts Flex Components is a set of native components which can be used both in Adobe Flex and Air applications. The example application you can see above was creating using Adobe Flex and amCharts Flex Components.

Supported chart types
Current version of amCharts Flex Components supports two main base chart types: pie (donut) and Cartesian charts. The latter can display a number of different charts including lines, step lines, smoothed lines and columns. All of these can be stacked or 100% stacked. The chart can be rotated by 90 degrees so columns can became bars. We will be adding additional types in the upcoming months.

Main features

• can accept and parse date/time-based data and display data points as well as data at custom/irregular intervals
• zooming
• scrolling
• any number of value axes
• logarithmic scale
• can be rotated by 90 degrees
• reversed value axis
• chart legend can hide/show chart items
• and a lot more…

Roadmap
The components are currently in beta stage. The plan is to release final version by the end of 2009. The following chart types will be added during this period: candlestick, ohlc, xy/bubble and radar/polar.
While charts are in beta phase, you can purchase them with a 30% discount. This is a good opportunity to test our next generation product early as well take advantage of the lower price offering. You will receive final version as well as any other minor versions released after that for free.
amStock Flex Component will be released in the first half of the 2010. As it is with our regular Flash-based charts it will be a separate product sold separately and not included in our basic chart package (amCharts Flex Components).

Differences from amCharts bundle
Users already using amCharts Bundle might ask – is amCharts Flex Components just a port to support Adobe Flex? The answer is no. amCharts Flex Components is a complete rewrite of our charts and are true native Adobe Flex components that bring all the easiness and development power Flex framework and Flex Builder has to offer. Furthermore the new charts are more powerful and feature-rich than current versions of our Flash-based charts.

Free usage
As with all other products from amCharts, you can use amCharts Flex Components for free. The only limitation of the free version is that a small link to this web site will be displayed in the top left corner of your charts.

Stock Chart’s main purpose is to display financial charts. However, it can also be used to visualize any date-based data. Line, column, candlestick, OHLC, step line and area – all these types of charts can be displayed with this control.

It’s a powerful application that lets you forget about most of the boring parts in building complex statistical systems in WPF. It has built-in period and data set selection tools, and can group data into longer periods. This enables you to make drill-down charts without any additional coding, using one data set only. Click on "MAX" button below the chart and the chart displays monthly data. Click the "1M" (one month) button, and the chart switches daily data. This is done without any data reloading! See this in action in the online in-browser demonstration.

Key features of amCharts Stock Chart for WPF:

• Support for numerous chart types
• Data grouping
• Multiple sub-charts
• News tickers (events)
• Multiple value axes
• Advanced scrollbar/zoom control
• Multiple data sets
• Data recalculation
• Support for data-binding

New features

Stock chart now supports milliseconds.

You can exclude the graph when calculating min and max values for the axis if you set <min_max>false</min_max> for this graph.

Fixed bugs

When all graphs of an axis are hidden, the grid lines and values of the axis dissapear.

Calling removeGraph() does not remove all the traces of the graph. (legend entries as well as Y-axis remains)

When redraw=true chart is resized properly but reverts to original width/height when rebuild() is called.

Changes in ASP.NET Controls for amCharts version 1.6.3.0:

• FEATURE ADDED: XY chart: added ZoomDisableAxis property. You can disable vertical or horizontal zoom. Set x to disable horizontal and y to disable vertical zoom.
• FEATURE ADDED: XY chart: added global BulletMaxSize and BulletMinSize properties.
• FEATURE ADDED: all charts: added ScientificMax and ScientificMin properties. These properties control limits when chart starts displaying values in scientific notation.
• FEATURE ADDED: all charts: added JsEnabled property. In case you don’t use any flash – JavaScript communication, you should set this setting to false – this will save some CPU and will disable the security warning message which appears when opening the chart from hard drive.
• FEATURE ADDED: Column chart, Line chart: ValuesDuration (column chart) and YLeftValuesDuration/YRightValuesDuration (line chart) properties added. In case you want your axis to display formatted durations instead of numbers, you have to set the unit of the duration in your data. For example, if your values in data represents seconds, set “ss” here.
• FEATURED ADDED: Column, Line and XY charts: added PercentileMargins property. When it’s set to true margin settings are treated as percentile values.
• BUGFIX: LineChart: DataLabelFormatString wasn’t sent to the flash controls in LineChartGraph

New settings <scientific_min> and <scientific_max> added. If absolute value of your number is equal or bigger then scientific_max or equal or less then scientific_min, this number will be formatted using scientific notation, for example:

15000000000000000 -> 1.5e16
0.0000023 -> 2.3e-6

amStock-only updates

NEW FEATURE: scrollers’ graph can now be "step" or "line". New setting <graph_type> was added to the <scroller> group. The default type is "line".

FIX: if start_on_axis was set to false and equal_spacing was set to true, the last grid line wasn’t displayed.

Bugs Fixed:

When <equal_spacing> was set to false cursor was not always snaping to the nearest bullet.

Selected predefined period button lost selected color after the chart was resized or a data set for comparing was changed.

Now if you do not specify value for the events that are not assigned to any graph they will be displayed directly on axis.

New Features:

<strict_min_max> setting was added. This setting goes to:
<charts><chart><values><y_left> (or <y_right>). If this is set to true, the axis will stay between Min and Max values even if there are graph points beyond those values. The parts of the graph that do not fit will be cropped. If this is set to false, the Min and Max values will be extended to fit the graph. The default value is false.

<frequency> for scroller graph. If your data set has a lot of values the scroller might significantly slow down the whole chart. (Provided you have some graph in the scroller). This new setting can help solve the problem. I.e. if you set <scroller><frequency>5</frequency></scroller>, the graph in the scroller will take only every 5th data point. Other values will be skipped.

<fade_others_to> setting was added. It goes to:
<charts><chart><legend>. When the user rolls-over a legend entry key, the other graphs will fade to this setting so that the rolled over graph would stand out from the rest. Recommended setting is 10-20. Most likely you should set <graphs_on_off> to false if you use this setting. [Example].

New JavaScript function, setEvents(events, remove_old) was added. It allows adding events at a runtime. Use default event XML syntax: <events><event>….</event></events>. If you set the remove_old to true, the old events will be removed. Default value is "false".

Custom background image can be loaded
A new setting, <background><file> was added. The file should be placed in the “path” folder.

Get and set status of a chart with JavaScript function
JavaScript functions for getting and setting current status of a chart added: if you call flashMovie.getStatus() function, the chart will return the current status of a chart in a query string, for example:

<code>from=2008-01-01&to=2008-03-05&main=4&comparing=6,3</code>

As you see, it returns the selected period, the id of the main data set and the ids of data sets, selected for comparing. To set this or some other status, you should call:

<code>flashMovie.setStatus(”from=2008-01-01&to=2008-03-05&main=4&comparing=6,3″);</code>

This is very comfortable when user navigates away from the page and you want to keep the same status when the user comes back.

JavaScript functions are called when main and comparing data sets are changed:
amSelectDataSet(chart_id, did) – called when main data set was changed
amCompareDataSet(chart_id, did) – called when data set for comparing was selected
amUncompareDataSet(chart_id, did) – called when comparing data set was unselected

Vertical legend
A new setting <legend_position> was added. The default value is “top”, the other available – “left” and “right”. In case you use “left” or “right”, you can control the width of the legend with the <legend_width> setting. The default value is 150. Check vertical legend example.

The items in the legend can arranged in the reverse order. 
A new setting, <reverse_order> was added to the chart’s legend settings.

The graph can be hidden when the chart is initialized.
If you set <graph><hidden>true</hidden></graph>, the graph will be hidden when the chart is first loaded. Check this example to see this in action.
