FusionCharts的钻取功能

FusionCharts的钻取功能

FusionCharts可以在点上定义钻取,实现各种link功能,包括:

(1)同一窗口实现钻取

(2)新窗口中实现钻取

(3)在指定的frame中实现钻取

(4) 在弹出窗口中实现钻取

(5) 触发js的函数

一. 同一窗口实现钻取

在set上定义link,如:

<set ... value='2235' ... link='ShowDetails.asp%3FMonth%3DJan' ...>

XML Example:

<chart caption='Monthly Sales Summary' subcaption='For the year 2006' xAxisName='Month' yAxisName='Sales' numberPrefix='$'>
<set label='Jan' value='17400' link='DemoLinkPages/DemoLink1.html'/>
<set label='Feb' value='19800' link='DemoLinkPages/DemoLink2.html'/>
<set label='Mar' value='21800' link='DemoLinkPages/DemoLink3.html'/>
<set label='Apr' value='23800' link='DemoLinkPages/DemoLink4.html'/>
<set label='May' value='29600' link='DemoLinkPages/DemoLink5.html'/>
<set label='Jun' value='27600' link='DemoLinkPages/DemoLink6.html'/>
</chart>

 

如果链接中带有?,&等字符,需用Encoded形式的字符,FusionCharts将对其进行解码。

热点中参数的传递:因为在XML中对特殊字符? & 不能识别FusionCharts对特殊字符提供了转义的支持所以在上面的link 参数传递改为<set … link=’ /chartDemo/link.jsp%3Fvalue%3D999> 要是在传一个参数是就得用&了
<set … link=’ /chartDemo/link.jsp%3Fvalue%3D999%26name=成都>
<set … link=’ /chartDemo/link.jsp?value=999&name=成都>

 

二。新窗口中钻取

要在新页面中打开链接,需在链接前增加n-字符,如

<set ... value='2235' ... link='n-ShowDetails.asp%3FMonth%3DJan' ...>

Example XML:

<chart caption='Monthly Sales Summary' subcaption='For the year 2006' xAxisName='Month' yAxisName='Sales' numberPrefix='$'>
<set label='Jan' value='17400' link='n-DemoLinkPages/DemoLink1.html'/>
<set label='Feb' value='19800' link='n-DemoLinkPages/DemoLink2.html'/>
<set label='Mar' value='21800' link='n-DemoLinkPages/DemoLink3.html'/>
<set label='Apr' value='23800' link='n-DemoLinkPages/DemoLink4.html'/>
<set label='May' value='29600' link='n-DemoLinkPages/DemoLink5.html'/>
<set label='Jun' value='27600' link='n-DemoLinkPages/DemoLink6.html'/>
</chart>

 

三 在指定的frame中实现钻取

要在指定的frame中打开链接,需在链接中指定frame的name,如:

<set ... value='2235' link='F-FrameName-ShowDetails.asp%3FMonth%3DJan' ... >

链接中第一个字符F:表示在frame中打开链接;其后加上连接符-,加上frame的名称,最后是链接的真正的url。

XML Example:

<chart caption='Monthly Sales Summary' subcaption='For the year 2006' xAxisName='Month' yAxisName='Sales' numberPrefix='$'>
<set label='Jan' value='17400' link='F-detailsFrame-../DemoLinkPages/DemoLink1.html'/>
<set label='Feb' value='19800' link='F-detailsFrame-../DemoLinkPages/DemoLink2.html'/>
<set label='Mar' value='21800' link='F-detailsFrame-../DemoLinkPages/DemoLink3.html'/>
<set label='Apr' value='23800' link='F-detailsFrame-../DemoLinkPages/DemoLink4.html'/>
<set label='May' value='29600' link='F-detailsFrame-../DemoLinkPages/DemoLink5.html'/>
<set label='Jun' value='27600' link='F-detailsFrame-../DemoLinkPages/DemoLink6.html'/>
</chart>

上面的html页面包含2个frameset,分别在上下位置,上面的frameset是主图,下面的frameset是根据上面的链接点击后显示图。Html格式如下:

The HTML code of FrameExample.html is as under:

<html>
<head>
<title>
FusionCharts Frame Drill-down example
</title>
</head>
<frameset rows="350,*" cols="*" frameborder="YES" border="1" framespacing="0">
<frame src="FramePages/FrameChart.html" name="chartFrame" scrolling="NO" noresize >
<frame src="FramePages/LowerFrame.html" name="detailsFrame" scrolling="Auto" noresize>
</frameset>
</html>

 

四. 在弹出窗口中打开链接

<set .. value='235' link="P-detailsWin,width=400,height=300,toolbar=no,scrollbars=no, resizable=no-ShowDetails.asp%3FMonth%3DJan" />

P-:表示在弹出窗口中打开

detailsWin: 指定弹出窗口名,如果每个点指定的弹出窗口名相同,则在同一个弹出窗口中打开这些链接;如果不同,将为每一个链接打开一个弹出窗口。

width=400,height=300,toolbar=no,scrollbars=no, resizable=no:弹出窗口属性;

ShowDetails.asp%3FMonth%3DJan:链接内容

 

可指定的弹出窗口属性:

height:弹出窗口高度,pixels

width: 宽度

resizable:窗口大小是否可变,若=yes表示可通过拖动边或角进行窗口的放大或缩小;Value = yes or no, 1 or 0.

Scrollbars:是否显示横向和纵向滚动条,Value = yes or no, 1 or 0.

Menubar:是否在顶部显示菜单栏,Value = yes or no, 1 or 0.

Toolbar:是否显示工具条,包括前进、后退、停止等工具按钮,Value = yes or no, 1 or 0.

Location:是否显示url地址栏,Value = yes or no, 1 or 0.

Directories:是否显示附加工具条,Value = yes or no, 1 or 0.

Status:是否在页面下方显示状态栏, Value = yes or no, 1 or 0.

Left:指定弹出窗口距左侧宽度,单位pixels,此属性应用于IENetscape用screenX

Top:指定弹出窗口距顶部宽度,单位pixels,此属性应用于IENetscape用screenY

Fullscreen:是否以全屏打开,只用于ie

 

Sample XML:

<chart caption='Monthly Sales Summary' subcaption='For the year 2006' xAxisName='Month' yAxisName='Sales' numberPrefix='$'>
<set label='Jan' value='17400' link='P-detailsPopUp,width=400,height=300,toolbar=no, scrollbars=no,resizable=no-DemoLinkPages/DemoLink1.html'/>
<set label='Feb' value='19800' link='P-detailsPopUp,width=400,height=300,toolbar=no, scrollbars=no,resizable=no-DemoLinkPages/DemoLink2.html'/>
<set label='Mar' value='21800' link='P-detailsPopUp,width=400,height=300,toolbar=no, scrollbars=no,resizable=no-DemoLinkPages/DemoLink3.html'/>
<set label='Apr' value='23800' link='P-detailsPopUp,width=400,height=300,toolbar=no, scrollbars=no,resizable=no-DemoLinkPages/DemoLink4.html'/>
<set label='May' value='29600' link='P-detailsPopUp,width=400,height=300,toolbar=no, scrollbars=no,resizable=no-DemoLinkPages/DemoLink5.html'/>
<set label='Jun' value='27600' link='P-detailsPopUp,width=400,height=300,toolbar=no, scrollbars=no,resizable=no-DemoLinkPages/DemoLink6.html'/>
</chart>

 

五):触发js函数

Js函数需在chart所在页面定义

<set label='USA' value='235' link="j-myJS('USA',235)"/>

j-:触发js函数myJS(),注意,其中不能用分号。

 

FusionCharts v3.1以上版本,还可用下面这种形式j-{user function name}-{parameter}:

<set label='USA' value='235' link="j-myJS-USA,235"/>

参数之间逗号分隔

<html>
<head>
<title>JavaScript Link Example</title>
<script language="JavaScript" src="../FusionCharts/FusionCharts.js"></script>
<SCRIPT LANGUAGE="JavaScript">
<!--
function myJS(myVar){
window.alert(myVar);
}
//-->
</SCRIPT>
</head>

<body bgcolor="#ffffff">
<div id="chartdiv" align="center">The chart will appear within this DIV. This text will be replaced by the chart.</div>
<script type="text/javascript">
var myChart = new FusionCharts("../FusionCharts/Column2D.swf", "myChartId", "500", "300", "0", "1");
myChart.setDataURL("JSExample.xml");
myChart.render("chartdiv");
</script>
</body>
</html>

Additionally, it's important to set the registerWithJS attribute in constructor to 1 (the last attribute in the line which initializes a FusionCharts chart in the page).

JSExample.xml:

<chart caption='ABC Bank Branches' subCaption='(In Asian Countries)' yaxislabel='Branches' xaxislabel='Country'>
<set label='Hong Kong' value='235' link='j-myJS-Hong Kong, 235'/>
<set label='Japan' value='123' link='j-myJS-Japan, 123'/>
<set label='Singapore' value='129' link='j-myJS-Singapore, 129'/>
<set label='Malaysia' value='121' link='j-myJS-Malaysia, 121'/>
<set label='Taiwan' value='110' link='j-myJS-Taiwan, 110'/>
<set label='China' value='90' link='j-myJS-China, 90'/>
<set label='S. Korea' value='86' link='j-myJS-S. Korea, 86'/>
</chart>

 

 

以上方式基本适用于所有浏览器。

下面的方式有时候IE不支持:

<set label='USA' value='235' link="JavaScript:myJS('USA, 235')"/>
