Hi,
This is how we use webcharts.
1. We save the project (WCP file) in a folder accessible by the CF server.
We use to save just WC3D style sheet but realised that we could just grab
that from the WCP file at run time and saving one project file is easier to
maintain than 2 files for each chart.
2. Create the XML Style from the WCP project. Could have parsed the
document into XML then then grabbed the frameChart element but this appeared
to be simplier and quicker. (example below)
<!--- Read the WCP file --->
<!--- Get the frameChart component --->
<cfset iStart = findNoCase("<frameChart",sChartStyle)>
<cfset iEnd = findNoCase("</frameChart>",sChartStyle)>
<cfsavecontent variable="chartStyle">
<cfoutput><?xml version="1.0" encoding="UTF-8"?>
#mid(sChartStyle,iStart,iEnd-iStart+13)#
</cfoutput>
</cfsavecontent>
3. Create the chart model XML (example below)
<cffunction name="getChartModel" returntype="string" access="public"
hint="Get chart model">
<cfargument name="qChartData" type="query" required="true">
<cfset var qChartDataStructure = arguments.qChartData>
<cfsavecontent variable="chartModel">
<cfoutput><?xml version="1.0" encoding="UTF-8"?>
<XML type="default">
<COL>Beef</COL>
<COL>Sheep</COL>
<ROW col0="100.0" col1="100.0">1990</ROW>
<ROW col0="111.790393" col1="108.9197225">1991</ROW>
<ROW col0="116.1572052" col1="94.54905847">1992</ROW>
<ROW col0="113.5371179" col1="80.57482656">1993</ROW>
<ROW col0="121.8340611" col1="86.0753221">1994</ROW>
<ROW col0="114.4104803" col1="67.34390486">1995</ROW>
<ROW col0="126.6375546" col1="78.49355798">1996</ROW>
<ROW col0="123.580786" col1="70.31714569">1997</ROW>
<ROW col0="146.7248908" col1="63.67690783">1998</ROW>
<ROW col0="144.5414847" col1="68.43409316">1999</ROW>
<ROW col0="117.0305677" col1="56.98711596">2000</ROW>
<ROW col0="122.7074236" col1="59.96035679">2001</ROW>
<ROW col0="135.371179" col1="58.67195243">2002</ROW>
<ROW col0="124.4541485" col1="47.32408325">2003</ROW>
<ROW col0="141.0480349" col1="47.27452924">2004</ROW>
</XML></cfoutput>
</cfsavecontent>
<cfreturn chartModel>
</cffunction>
4. Call the webcharts engine directly
<cfscript>
oMyWebChart = createObject("Java","
com.gp.api.jsp.MxServerComponent");
oMyApp = getPageContext().getServletContext();
oSvr = oMyWebChart.getDefaultInstance(oMyApp);
oMyChart2 = oSvr.newImageSpec();
oMyChart2.width = this.chartXSize;
oMyChart2.height= this.chartYSize;
oMyChart2.type = this.chartType;
oMyChart2.style = "#chartStyle#";
oMyChart2.model = "#chartModel#";
</cfscript>
<!--- Create html tag set --->
<cfsavecontent variable="chartImgTag">
<cfoutput>#oSvr.getImageTag(oMyChart2,"#this.analURL#")#</cfoutput>
</cfsavecontent>
<!--- Good old Webcharts loves to add an extra /Images/ to the
URL --->
<cfset chartImgTag =
replace(chartImgTag,"#this.analURL#Images/","#this.analURL#","All")>
5. Use the resultant HTML in your web page.
So there is probably some errors in the code presented here as I have just
cut and past from our analysis engine but it will work with a little
tweeking.
Hope it helps.
