Question

I have a couple of queries which pull data for use in a graph.

<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>

The graph code is

<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>

this gives me the following graph

How do I get the data displayed sorted by the total of the stacked elements?

@ Ben

That got me on the right track, I didnt previously know QOQ could combine 2 completely different queries

<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 simplest way would be to use a 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’ve not tested this, so you may need to tweak it a little.

Now, you should be able to use the two Referrals columns as the data columns for the graph.
