Coldfusion cfchart stacks

Question

I have several queries that retrieve data for use in graphics.

<cfquery name='clusterPrivateReferrals'  dbtype="query">
SELECT organisationName, count(messageID)*1000/listSize as msgCount
FROM clusterReferrals
WHERE datecreated>#refRateStartDate#
AND refTypeID=3
GROUP BY organisationName, listSize
</cfquery>

<cfquery name='clusterNHSReferrals'  dbtype="query">
SELECT organisationName, count(messageID)*1000/listSize as msgCount
FROM clusterReferrals
WHERE datecreated>#refRateStartDate#
AND refTypeID<>3
GROUP BY organisationName, listSize
</cfquery>

Graph code

<cfchart format="flash" title="Cluster referrals per 1000 patients from #dateformat(refRateStartDate, 'dd-mmm-yy')#" chartWidth="470" chartHeight="380" fontSize="12" style="chart.xml" seriesPlacement = "stacked" showLegend = "yes">
    <cfchartseries type="bar" seriescolor="##FFD800" seriesLabel="Private" query="clusterPrivateReferrals" valueColumn="msgCount" ItemColumn="organisationName">
    </cfchartseries>
    <cfchartseries type="bar" seriescolor="##F47D30" seriesLabel="NHS" query="clusterNHSReferrals" valueColumn="msgCount" ItemColumn="organisationName">
    </cfchartseries>
</cfchart>

it gives me the following chart

How to get the displayed data, sorted by the sum of the elements of the folded elements?

@Ben

This led me to the right path, I did not know before that QOQ can combine 2 completely different requests

<cfquery name='clusterPrivateReferrals'  dbtype="query">
SELECT organisationName, count(messageID)*1000/listSize as privateRate
FROM allReferrals
WHERE datecreated>#refRateStartDate#
AND refTypeID=3
GROUP BY organisationName, listSize
</cfquery>

<cfquery name='clusterNHSReferrals'  dbtype="query">
SELECT organisationName, count(messageID)*1000/listSize as nhsRate
FROM allReferrals
WHERE datecreated>#refRateStartDate#
AND refTypeID<>3
GROUP BY organisationName, listSize
</cfquery>

<cfquery name="stackOrder" dbtype="query">
    select clusterPrivateReferrals.privateRate,
        clusterNHSReferrals.nhsRate,
        clusterPrivateReferrals.organisationName,
        (clusterPrivateReferrals.privateRate + clusterNHSReferrals.nhsRate) as totalRate
    from clusterPrivateReferrals, clusterNHSReferrals
    WHERE clusterNHSReferrals.organisationName = clusterPrivateReferrals.organisationName
    order by totalRate desc
</cfquery> 

Answer 1

The easiest way is to use QofQ:

<cfquery name="stackOrder" dbtype="query">
    select clusterPrivateReferrals.msgCount as privateReferrals,
        clusterNHSReferrals.msgCount as NHSReferrals,
        clusterPrivateReferrals.organizationName
    from clusterPrivateReferrals
    join clusterNHSReferrals on clusterNHSReferrals.organizationName = clusterPrivateReferrals.organizationName
    order by (privateReferrals+privateReferrals) desc
</cfquery>

I have not tested this, so you may need to tweak it a bit.

You can now use the two Referrals columns as data columns for the graph.

Answer 2

, QoQ ? - ( , ):

<cfquery name='clusterCombinedReferrals'  dbtype="query">
SELECT organisationName, messageID, listSize, count(messageID)*1000/listSize as totalMsgCount
FROM clusterReferrals
WHERE datecreated>#refRateStartDate#
GROUP BY organisationName, listSize
</cfquery>

, select clusterCombinedReferrals totalMsgCount , , .

Answer 3

, , cfchartdata cfchartseries.

- , . , , , . ( !) , . , .

<cfset data = {}>

<cfloop from="1" to="#clusterPrivateReferrals.recordCount#" index="x">

  <cfset structInsert(data, clusterPrivateReferrals["organisationName"][x], {})>

  <cfset data['#clusterPrivateReferrals["organisationName"][x]#'].private = clusterPrivateReferrals["msgCount"][x]>

  <cfset data['#clusterNHSReferrals["organisationName"][x]#'].nhs = clusterPrivateReferrals["msgCount"][x]>

  <cfset data['#clusterPrivateReferrals["organisationName"][x]#'].total = data['#clusterNHSReferrals["organisationName"][x]#'].private + data['#clusterNHSReferrals["organisationName"][x]#'].nhs>

</cfloop>

<cfset sorted = structSort(data, "numeric", "desc", "total")>
