Asp.net实例：amCharts(.net版)实现图形报表

阅读更多

第一步

当然是要添加dll引用

然后再把相关文件放到目录里

就像在项目里添加FCK编辑器一样

这样的话.开始的环境就好了

我的目录结构是这样的



当然只是为了测试,就没有那样去什么什么了
当然,在每个页的开始要注册一下这个dll
<%@ Register Assembly="am.Charts" Namespace="am.Charts" TagPrefix="cc1" %>
然后就可以用了

饼图

后台代码


Code
protected void Page_Load(object sender, EventArgs e)
{
for (int i = 0; i < 10; i++)
{
//PieChartDataItem pcd = new PieChartDataItem("刘巨" + i.ToString(), i);
PieChartDataItem pcd1 = new PieChartDataItem();
pcd1.Description = "Description" + i.ToString();
pcd1.Title = "刘巨" + i.ToString();
//设置点击时候的链接
//pcd1.Url = "http://www.cnblogs.com/liuju150/";
pcd1.LabelRadius = 1;
pcd1.Value = i;
pcd1.PullOut = true;
PieChart1.Items.Add(pcd1);
}
PieChart1.Width = 600;
PieChart1.Height = 500;
//设置链接的跳转方式
//PieChart1.SliceLinkTarget = "_blank";
PieChart1.ScientificMax = 20;
PieChart1.Labels.Add(new ChartLabel("测试饼图", new Unit(100), new Unit(20)));
PieChart1.ToolTip = "测试饼图2";
}


柱型图

后台代码

Code
protected void Page_Load(object sender, EventArgs e)
{
DataSet ds = new DataSet("column");
DataTable dt = new DataTable("columnTable");
DataColumn dc_y = new DataColumn("year");
DataColumn dc_v = new DataColumn("val");

DataColumn dc_v1 = new DataColumn("val1");

dt.Columns.Add(dc_y);
dt.Columns.Add(dc_v);
dt.Columns.Add(dc_v1);
Random rd = new Random();
for (int i = 2000; i < 2010; i++)
{
DataRow dr = dt.NewRow();
dr[dc_y] = i.ToString();
dr[dc_v] = (rd.NextDouble() * i).ToString();
dr[dc_v1] = (rd.NextDouble() * (i + i / 3)).ToString();
dt.Rows.Add(dr);
}
ds.Tables.Add(dt);

//立体感觉深度
ColumnChart1.Depth = 10;
//动态升长时间
ColumnChart1.ColumnGrowTime = 5;
ColumnChart1.Width = new Unit(600);
ColumnChart1.Height = new Unit(500);
ColumnChart1.PlotAreaBackgroundColor = Color.Yellow;

ColumnChart1.ChartDirectory = "~/amcharts/amcolumn/";
//柱型1
ColumnChartGraph ccg = new ColumnChartGraph();
ccg.DataSource = ds;
ccg.DataSeriesItemIDField = "year";
ccg.Title = "测试";
ccg.DataValueField = "val";
//形状,可以是柱型,也可以是线型
ccg.GraphType = ColumnChartGraphTypes.Column;
ColumnChart1.Graphs.Add(ccg);

ColumnChartGraph ccg1 = new ColumnChartGraph();
ccg1.DataSource = ds;
ccg1.DataSeriesItemIDField = "year";
ccg1.Title = "测试1";
ccg1.DataValueField = "val1";
ccg1.GraphType = ColumnChartGraphTypes.Column;
ColumnChart1.Graphs.Add(ccg1);

//设置上面显示的文字格式
ColumnChart1.ColumnDataLabelFormatString = "{value}";
ColumnChart1.LineBalloonTextFormatString = "{value}";

ColumnChart1.DataSource = ds;
ColumnChart1.DataSeriesIDField = "year";
ColumnChart1.DataBind();
}
线型图

后台

Code
protected void Page_Load(object sender, EventArgs e)
{
//自己添加一个数据
DataSet ds = new DataSet("Line");
DataTable dt = new DataTable("LineTable");
DataColumn dc_y = new DataColumn("year");
DataColumn dc_v = new DataColumn("val");

DataColumn dc_v1 = new DataColumn("val1");

dt.Columns.Add(dc_y);
dt.Columns.Add(dc_v);
dt.Columns.Add(dc_v1);
Random rd = new Random();
for (int i = 1987; i < 2010; i++)
{
DataRow dr = dt.NewRow();
dr[dc_y] = i.ToString();
dr[dc_v] = (rd.NextDouble() * i).ToString();
dr[dc_v1] = (rd.NextDouble() * (i + i / 3)).ToString();
dt.Rows.Add(dr);
}
ds.Tables.Add(dt);

//设置图形的长高
LineChart1.Width = new Unit(600);
LineChart1.Height = new Unit(400);

//添加一个线条
LineChartGraph lcg = new LineChartGraph();
//这里是线条峰点的形状(正方形):实心圆,空心圆.
lcg.Bullet = LineChartBulletTypes.Square;
//这里是线条的颜色
//lcg.BulletColor = Color.Yellow;
//向下面积的颜色
lcg.FillColor = Color.Yellow;
//向下面积的透明度
lcg.FillAlpha = Convert.ToByte(40);
//Y轴值在右边(默认在左边)
lcg.Axis = LineChartAxes.Right;

lcg.DataSource = ds;
lcg.DataSeriesItemIDField = "year";
lcg.DataValueField = "val";
lcg.Title = "测试1";
LineChart1.Graphs.Add(lcg);

//添加第二个线条
LineChartGraph lcg1 = new LineChartGraph();
lcg1.Bullet = LineChartBulletTypes.RoundOutline;

lcg1.DataSource = ds;
lcg1.DataSeriesItemIDField = "year";
lcg1.DataValueField = "val1";
lcg1.Title = "测试2";
LineChart1.Graphs.Add(lcg1);

LineChart1.DataSource = ds;
LineChart1.DataSeriesIDField = "year";
LineChart1.DataBind();
