Coldfusion cfchart堆叠顺序

Question

我有几个查询来提取数据，以便在图中使用。

<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>

图形代码是

<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>

这给出了下面的图

如何使显示的数据按堆叠元素的总数排序？

@ Ben

这让我走上了正确的道路，我以前不知道QOQ可以组合两个完全不同的查询

<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

最简单的方法是使用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>

我还没有测试过这个，所以你可能需要稍微调整一下。

现在，您应该能够使用两个引用列作为图形的数据列。

Answer 2

也许可以添加只按日期过滤的中间QoQ？类似这样的东西(无法测试，因此可能需要一些修复)：

<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>

在将现有查询更新为首先包含select from clusterCombinedReferrals和order by totalMsgCount之后，还应删除已应用的按日期过滤。

Answer 3

我认为，如果不先将查询输出到一个结构，然后对其进行排序，并在每个cfchartseries中使用cfchartdata标记输出数据，就不能这样做。

就像这样，也许。我在本地做到了这一点，它是有效的，但后来我尝试将代码转换为使用您的查询和列名，因此它可能无法直接复制和粘贴。(但也有可能！)它还假设两个查询的长度始终相同。如果这不是真的，你可能需要围绕这一点进行编码。

<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")>

<cfchart format="flash" title="data" chartWidth="470" chartHeight="380" fontSize="12" seriesPlacement = "stacked" showLegend = "yes">

    <cfchartseries type="bar" seriescolor="##FFD800" seriesLabel="Private">
        <cfloop from="1" to="#arrayLen(datas)#" index="x">
            <cfchartdata item="#sorted[x]#" value="#data['#sorted[x]#'].private#">
        </cfloop>
    </cfchartseries>

    <cfchartseries type="bar" seriescolor="##F47D30" seriesLabel="NHS">
        <cfloop from="1" to="#arrayLen(datas)#" index="x">
            <cfchartdata item="#sorted[x]#" value="#data['#sorted[x]#'].nhs#">
        </cfloop>
    </cfchartseries>

</cfchart>
