cfchart error

Jul 25, 2011 7:49 PM

hello all, i did a search on this but found nothing

 

i am running ubuntu 10.04

railo 3.2.3 final

tomcat

mysql

 

Anyway, I am trying to figure out if this is a coldfusion vs server type error

 

I am trying to create a line chart. I try to fill up cfchart series from some items I am pulling from my database. When I do this, the following message is shown: Band count exceeds non-unity number of constants.

 

When I restrict it to just one single item in the cfchartseries, it still gives the same message. How does one properly use the cfchart?

    You are probably not getting much of a response because this forum is for Adobe ColdFusion questions. The best place for Railo specific questions is their mailing list

    Code would help.

     

    It almost sounds like a divide by zero??? Have you dumpded the queries

    to ensure you have data for both axis'?

    <cfinclude template="Application.cfm">
    <cfinclude template="header.cfm">

     

    <cfset userEntries = functionsObj.getNumUserEntries(session.user_id)>

     

    <cfif userEntries GTE 8>
        <cfoutput>
        <cfchart format = "png" showborder="yes" chartheight="300" chartwidth="400"
             yaxistitle="Estimated strength for day" xaxistitle="day">
        <cfloop index="i" from="1" to="4">
                <cfset lift = functionsObj.getCoreLiftsForDay(i)>
                <cfchartseries type="line" serieslabel="#functionsObj.getLiftNameFromId(i)#">
                <cfloop query="lift">
                    <cfif WAVE NEQ 4>
                        <cfchartdata item="C#CYCLE#W#WAVE#" value="#functionsObj.findMax(WEIGHT3,REPS,i)#">
                    </cfif>
                </cfloop>
                </cfchartseries>
            </cfloop>
        </cfchart>
        </cfoutput>
    <cfelse>
        You must log some more information before statistics can be gathered.
    </cfif>

     

    <cfinclude template="footer.cfm">

     

    ------

     

    One thing that has changed: I put in format="png" and now I no longer get the error, the page displays but with a broken image where the chart should be.

     

    There is no divide by zero going on, I have verified this.

    Well this is getting over my head...

     

    That said, two observations:

     

    Why are you including application.cfm?it should load automatically and 

    this cfinclude would run it twice.

     

    If it's running fine on other browsers it's not likely the problem is 

    not likely with your use of  tags.

     

    If I were you I'd pose the question an the advanced forum instead of 

    getting started. And emphisise the browser platform issue. Also try tek-tips.com

     

    Much luck
