Visifire是利用Silverlight 2.0 beta 1開發的不錯的Chart解決方案.利用它可以很容易的把其加入到各種技術方式實現的BS方案中的項目中去.按照官方的文檔,只要加入一個xml文件就可 以了,比如:

<vc:Chart xmlns:vc="clr-namespace:Visifire.Charts;assembly=Visifire.Charts"
Theme=&quot;Theme3" AnimationType="Type3">

  <vc:Title Text="Athens 2004 Olympics"/>
<vc:AxisX Title="Country"/>
<vc:AxisY Title="Gold Medals Won"/>

  <vc:DataSeries RenderAs="Column"  LabelEnabled="True">
<vc:DataPoint AxisLabel="USA" YValue="35"/>
<vc:DataPoint AxisLabel="China" YValue="32"/>
<vc:DataPoint AxisLabel="Russia" YValue="27"/>
<vc:DataPoint AxisLabel="Australia" YValue="17"/>
<vc:DataPoint AxisLabel="Japan" YValue="16"/>
</vc:DataSeries>
</vc:Chart>

　　不過對于開發人員來說這樣一定很不爽,既然是開源的.net下的東西,為什么不能在程序中控制它呢?Sunil的這個文章向大家介紹了如何去做:

　　其實看下面的代碼就很清晰了：

Visifire.Charts.Chart visiChart = new Visifire.Charts.Chart();
Visifire.Charts.DataSeries dataSeries = new Visifire.Charts.DataSeries();
Visifire.Charts.DataPoint dataPoint;
Visifire.Charts.Title title = new Visifire.Charts.Title();

title.Text = "Click On Chart To Refresh";
visiChart.Children.Add(title);

visiChart.Width = 500; // Width and Height are required for the Chart.
visiChart.Height = 300;

Random rand = new Random(DateTime.Now.Millisecond);

for (int i = 0; i < 9; i++)
{
dataPoint = new Visifire.Charts.DataPoint();
dataPoint.YValue = rand.Next(100, 1000);
dataSeries.Children.Add(dataPoint);
}

dataSeries.RenderAs = "Point";
visiChart.Children.Add(dataSeries);

LayoutRoot.Children.Clear(); // So that Chart objects don’t build up each time we add one.
LayoutRoot.Children.Add(visiChart);
