amCharts introduces Flex components

Friday, October 30th, 2009

We are proud to introduce you a brand new product – amCharts Flex Components.

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 for WPF Released

Tuesday, October 20th, 2009

amCharts has released their financial charting component for Windows Presentation Foundation – amCharts Stock Chart for WPF.

DataSet comparison in Stock Chart

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.

Candlestick and Column Stock Chart

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
  • Look-less WPF control

More details could be found here.

As all other amCharts products Stock Chart for WPF could be used absolutely FREE even in commercial applications under link-ware license (a small link back to amCharts website on the screenshot above). Additionally we are running 50% discount on all link-free licenses until the end of October 2009. Click here for details.

Firefox Team Disables WPF Plug-in

Saturday, October 17th, 2009

On October 16, 2009 Firefox team has added WPF plug-in to the plug-in blocklist effectively disabling all the XBAP WPF applications in Firefox. The block is due to recently discovered vulnerability. At this point it’s unclear for how long this block is going to be in effect.

amCharts for WPF demonstrations on this site utilize the above mentioned XBAP WPF technology and are therefore affected by this block. In case you can’t open the demonstrations in Firefox, you should try them with Internet Explorer.
