问题描述
请考虑以下代码，现在我的 <body> 标签内的 .cfm 页面中有以下代码:
Please consider the following code, right now I have the following code in my .cfm page inside the <body> tag:
DataSource = xx.xx.x.xx
Name of the database = sgemail
Name of the relevant column = event_vc
基本上我已经计算了以下查询中打开连接的百分比.
Basically I have calculated the percentage of the open connections in the following queries.
<cfquery datasource = "xx.xx.x.xx" name="qSen">
SELECT (select count(*)
FROM sgemail) AS TOTAL_CONNECTIONS,
(SELECT count(*)
FROM sgemail
WHERE event_vc = "open") AS OPEN_CONNECTIONS,
(ROUND((SELECT OPEN_CONNECTIONS / (TOTAL_CONNECTIONS))*100)) AS "% OPEN" ;
</cfquery>
<cfquery datasource = "xx.xx.x.xx" name="qSen">
SELECT (select count(*) from sgemail) AS TOTAL_CONNECTIONS,
(SELECT count(*) from sgemail where event_vc = "BOUNCE") AS BOUNCE_CONNECTIONS,
(ROUND((SELECT BOUNCE_CONNECTIONS / (TOTAL_CONNECTIONS))*100)) AS "% BOUNCE" ;
</cfquery>
基本上"% OPEN" 和`"% BOUNCE" 用于显示连接打开和从数据库反弹的百分比.
Basically "% OPEN" and `"% BOUNCE" are used to display the percentage of connections open and bounce from the database.
我在上面的 <cfquery> 标记下面包含了以下 <cfchart> 标记，如下所示:
I have included the following <cfchart> tag below the above <cfquery> tag as follows:
<cfchart
format="png"
scalefrom="0"
scaleto="1200000"
pieslicestyle="solid">
<cfchartseries
type="pie"
serieslabel="Website Traffic 2006"
seriescolor="blue"
query = "qSengrid"
valuecolumn="% OPEN"
itemcolumn=""
>
</cfchartseries>
</cfchart>
我的问题:
1) 问题是上面的图表只显示了一个黄色圆圈.我想在一个图表中显示两个查询检索到的信息.例如我为 %OPEN 获得的值是 30，我为 %Bounce 获得的值是 20.我还有其他查询返回不同的值，这使得整个饼图到 100，但为了这个问题的简单起见，我只包含了两个 cfqueries.请让我知道如何进行下一步.
1) The thing is that the above chart is displaying only one circle with yellow color. I want to display the information retrieved by both the queries in one chart. For example
the value I'm getting for %OPEN is 30 and value I'm getting for %Bounce is 20. I have other queries as well which return different values which makes the whole pie chart
to 100 but I have included only two cfqueries for the sake of simplicity for this question. Please let me know how to proceed further.
2) 另外，当我注释掉第二个查询(我得到 % Bounce 值的地方)时，我可以在旁边看到 %OPEN 的值饼图的圆圈.但是，当我同时运行上面提到的只有一个 <cfchart> 的查询(使用 valuecolumn = %OPEN )我看不到圆圈旁边写的任何值.
2) Also, when I commented out the second query (where I'm getting % Bounce value), I can see the value of %OPEN next to the circle of the pie-chart. However, when I run both
the queries with only one <cfchart> mentioned above (with valuecolumn = %OPEN ) I can't see any value written next to the circle.
请回答我的上述问题，如果有任何问题我可以回答，请告诉我.
Please answer my above questions and let me know if there are any questions I can answer.

通过重复使用相同的查询名称，您很可能会覆盖以前的结果.此外，这不是 <cfchartseries query="..."> 的工作方式.它接受 single 查询，这意味着所有值必须包含在同一个查询中.
By using reusing the same query name, you are most likely overwriting the previous results. In addition, that is not how <cfchartseries query="..."> works. It accepts a single query, which means all of the values must be contained in the same query.
如果您必须使用单独的查询，请为每个查询指定一个唯一的名称，并为 每个 值使用单独的 <cfchartdata> 标记:
If you must use separate queries, give each query a unique name and a use separate <cfchartdata> tag for each value:
<cfchart format="png">
<cfchartseries type="pie">
<cfchartdata item="% Open" value="#qTotalOpen.TotalNumber#">
<cfchartdata item="% Bounce" value="#qTotalBounced.TotalNumber#">
... other values ...
</cfchartseries>
</cfchart>
