amCharts & amMap blog

We are happy to announce the release of the new version of amCharts Flex Components. The following features were added since the first release:

• candlestick and OHLC (open/high/low/close) graph types are now supported.
• negativeLineColor and negativeFillColors styles added to AmGraph. These styles allow coloring of negative part of line graph or negative columns with different color.
• Cartesian charts can be scrolled and zoomed with mouse wheel.
• Cartesian charts now support rotated axis values.
• Columns can now have rounded corners.
• Custom bullets can be used.
• Cartesian charts now support guides – both vertical and horizontal.

These are all main features we planned to add to Cartesian chart component until the final release.  We plan to add XY and Radar charts to the component set before the end of 2009.

We’ve updated our ASP.NET Controls for amCharts to support new features of 1.6.4.0 version of flash components. A couple of bugs were fixed along the way. Here’s a change log:

• FEATURES ADDED: XyChart: FillColor, FillAlpha and MinMax properties added
• FEATURE ADDED: ColumnChart: ColumnHoverColor property added.
• FEATURE ADDED: ColumnChart: ColumnCornerRadiusTop and ColumnCornerRadiusBottom properties added
• BUGFIX: PreloaderForeColor and PreloaderBackgroundColor where not rendered properly when using know color names (Black, White, etc.)
• BUGFIX: PieChart: when custom Colors where not set and AppendSettingsToExternal property was set to true, custom colors in external settings file where overridden by defaults
• BUGFIX: LineChart: YRightGridXxx settings were not applied unless some non-default setting was set on the YLeftGridXxx

We have just released new versions of all the charts in amCharts Bundle (Column & Bar, Line & Area, Pie & Donut, Scatter & Bubble, Radar & Polar charts) [Download]

Heres a scoop of what’s been added:

Column & Bar Chart

• FEATURE ADDED:

  Column corner radius

  Now columns can have rounded corners. Two different settings allow you specify different corner radiuses for columns top and bottom. You can also set the roundness in percents:

  <column>
     <corner_radius_top>100%</corner_radius_top>
     <corner_radius_bottom>8</corner_radius_bottom>

  [Sample]

• FEATURE ADDED:

  Roll-over color for the columns. Previously you could only set the roll-over
  brightness. Now you can set a color to which the column will change when user rolls-over the column:
  <column>
    <hover_color>#CC0000</hover_color>

Scatter & Plot (XY) Chart

• FEATURE ADDED
  New settings added to the <graph>:
  <fill_color> – sets the fill color of the graph. Note, the fill will work differently then in Line chart – it won’t fill the area between graph and axis, but rather fill the shape of the graph.
  <fill_alpha>  – sets fill opacity.
  <min_max> – you can tell the chart that it shouldn’t include graphs values when calculating min and max of the chart.
  The settings above allows you to simulate guides, draw colored areas on your chart. Check bulls_eye example to see this in action. [Sample]

All Charts 

• FEATURE ADDED
  amReturnParam function also returns the param name:
  amReturnParam(chart_id, value, param);

We have just released new version of amStock 1.2.0.0 [Download]

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);
