Stock Chart for WPF & Silverlight v.1.3 Released

July 21st, 2010

We have just released version 1.3 of amCharts Stock Chart for WPF & Silverlight. This version focuses on data grouping improvements. Several intermediate grouping points were added to make grouping switching smoother in time range.

Note: if you’ve used DataGroupingInterval enumeration explicitly in your code make sure to recompile your project against new dll and verify that your code is working properly.

Here’s a complete change log:

  • FEATURE ADDED: added more DataGroupingInterval values for smoother grouping in "time" range. NOTE: if your code used DataGroupingInterval enum directly make sure everything works as expected since values were inserted between other values.
  • FEATURE ADDED: added StockChart.MinimumDataGroupingInterval and MaximumDataGroupingInterval properties to constrain automatic data grouping interval switching
  • COSMETIC IMPROVEMENT: when Brush is set on Candlestick graph, the value is used for candle outline.
  • BUGFIX: in some scenarios it wasn’t possible to modify control template under Silverlight
  • BUGFIX: in some scenarios ArgumentOutOfRangeException was thrown when hovering over an empty chart.
  • BUGFIX: in some cases exception was thrown when hovering over an empty chart plot area
  • BUGFIX: Collapsing and showing charts (using Chart.Collapse()/Show() methods) sometimes resulted in charts overlapping
  • BUGFIX: in Raw (milliseconds) mode Value field data was used instead of Volume
  • BUGFIX: when ArrowUp bullet was set on axis it wasn’t visible
  • COSMETIC FIX: mouse cursor wasn’t returning to regular Arrow after mouse was released after dragging/scrolling the chart.

amStock 1.3.0.0 Released

July 14th, 2010

We just released amStock 1.3.0.0 of amStock with a whole bunch of new and exciting features [Download]. Here’s the list:

Logarithmic Scale for Y-axis

Value axes can now use logarithmic scale. set <values><y_left><logarithmic> to true in order to make axis logarithmic. Note, logarithmic axis can’t display values less or equal to zero. For this reason log scale won’t be used when comparing data sets and values are recalculated to percent.

Axis can be switched to logarithmic and backwards using JavaScript function setLogarithmic(chartId, axis, param). For example:

flashMovie.setLogarithmic(0, "left", true);

 

Trend Lines [Example]

Users of the chart can now draw trend lines. To enable drawing, set
<chart_trend_lines><drawing_enabled> to true. There are some more settings in this group which allows controlling color, opacity and some more properties of the lines.

When drawing is enabled, pencil and eraser icons appear on top right corner of the chart. Check drawing_trend_lines example to see this in action.

The same as events, trend lines can also be loaded from the file – file name is specified for each data set, using <trend_lines_file_name> setting. Check trend_lines.xml for an example of trend lines file.

Trend lines can be added directly to the settings file:

<data_set>
   <trend_lines>
      <trend_line>

Using the same syntax as in the trend_lines.xml file.

You can also set trend lines with JavaScript function flashMovie.setTrendLines(trend_lines, remove_old); where trend_lines is the same XML (one line sring).

Trend lines can be shown or hidden with these JS functions:

flashMovie.showTrendLines()
flashMovie.hideTrendLines()

 

Set Week Start

It is now possible to define a weekday from which a week starts. Usually this is important for countries, where trading starts on Sunday. So, if your week starts on Sunday, set:

<date_formats>
  <first_week_day>0</first_week_day>

0 is for Sunday, 1 – Monday, etc. The default value is 1.

Quick Charts for WPF & Silverlight v.1.0 Beta Released

May 10th, 2010

We are happy to announce availability of feature complete version of amCharts Quick Charts for WPF & Silverlight.

Quick Charts is an easy to use, fast set of charting controls for WPF & Silverlight. And it’s FREE and Open Source (Ms-PL)!

http://wpf.amcharts.com/lib/screenshots/quickcharts.png

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.

Key features:

  • Ease of use

    By analyzing user feedback we’ve determined what features are most important to the majority of scenarios and left everything else out. As a result we have an API that is very easy to master.

  • Speed

    Absence of complicated rarely used features let’s the charts do what they do fast.

  • Small footprint

    Current version is only 54kb uncompressed and in compressed form it’s only 19kb! This is especially important in Silverlight where every byte counts.

  • Support for essential chart types

    QuickCharts support Line, Column, Area and Pie charts.

  • Automatic axes and grid

    Serial chart automatically recalculates and rearranges axes and grids based on chart size (try resizing panes in the demo above).

  • Support for data-binding

    As any other bindable WPF and Silverlight controls quick charts can be bound to any data object implementing IEnumberable interface.

  • Free, unbranded & Open Source

    Quick Charts are absolutely free. There’s no branding, link backs or anything like that. And source code is released under very permissive Ms-PL license.

Beta version of amCharts Quick Charts for WPF & Silverlight is available for immediate download.
