cfchart & cfchartseries

Hi all

I'm new to this forum and realy hope somebody can and is willing to help me.

I try to make charts with the cfchart & cfchartseries tags.

To make a start I used the turorial from Ben Forta on
http://www.informit.com/articles/article.asp?p=31574

But everything is going wrong from the beginning.
The following part of the script is from the beginning from the tutorial and should show an empty chart:

Code:

<cfchart showborder="yes"
 chartheight="300" 
 chartwidth="400"
 yaxistitle="Projected Population (Millions)" 
 xaxistitle="Year">
 <cfchartseries type="line" serieslabel="United States">
 </cfchartseries>
</cfchart>

But even that is not working as you can see in the example I made:
http://www.testfolder.com/test.cfm

Does somebody see what i'm doing wrong, or what is wrong in the script.

Thanks in advance

This particular error

Code:

 Query not found: expenses
 
The error occurred in /home/httpd/vhosts/testfolder.com/httpdocs/test.cfm: line 9

7 : <body bgcolor="#FFFFFF" text="#000000">
8 : <cfchart format="flash" chartheight="300" chartwidth="500" showborder="yes" show3d="yes" tipstyle="mouseOver" pieslicestyle="sliced">
9 :  <cfchartseries type="pie" query="expenses" itemcolumn="expenseType" valuecolumn="expense" />
10 :  </cfchart>
11 :

means that you are trying to chart the data of a query that doesn't exist. CFchart and CFcharseries usually work by plotting the results of a particular query, but you can also hard-code the values in. The best place to know how CFchart works is by visiting here

Hope that helps out a little

If it doesn't post back and I'll try to help some more

Alas, the problem with that is that it is manually inseting individual data points into the chart one by one. From the poster's question, it seems like they want to populate it with a query, which is indeed possible with CFCHART (assuming the query exists of course).
