                <cfloop query="qry_subproperty"> 
                     <cfset variables.Yearquarter=ObjPropDetails.JoinYearQuarter(qry_subproperty.Yearquarter)>            
                 <cfchartdata item="#variables.Yearquarter#" value="#round(qry_subproperty.Gross)#" >
                </cfloop>              
            </cfchartseries>

Answer 1

You can set the max-value and step interval through the yAxis property in cfchart. These values can be dynamic. You can also set an array of values if you want "values":[0,200,400,600,800,1000]. The scalefrom ,scaletop and the interval(eg values:100:500:10) technique doesn't appear to work. But like I said you can get the same result using max-value and step.

<cfset yAxis = {"min-value":"0","max-value":"1000","step":"200"}>
<cfchart  
     format="#format#" yAxis="#yAxis#" 
       chartheight="320" chartwidth="690"  showborder="yes" 
    title="Trend in Subject Rents" style="20currency.js" name="TwntyQtrGraph1" tipstyle="mouseOver" 
    tooltip="#Deserializejson(stc_fields)#"  gridlines="#GraphInterval#">  
     <cfchartseries type="line" 
             serieslabel="Gross"
             seriescolor="navy"  markerStyle="diamond" paintStyle="plain" > 
            <cfloop query="qry_subproperty"> 
                 <cfset variables.Yearquarter=ObjPropDetails.JoinYearQuarter(qry_subproperty.Yearquarter)>            
             <cfchartdata item="#variables.Yearquarter#" value="#round(qry_subproperty.Gross)#" >
            </cfloop>              
        </cfchartseries>
</cfchart>
