Same item column(s) different valuecolumns

Question

When trying to output a chart with the same itemcolumn
values, but different valuecolumn values cfchart only graphs the
second one. I would expect to get two slices of apples, one
equaling 10, the other 15, but I only get the 15. I'd even settle
for 25 apples!
apples - 10
apples - 15
oranges - 20
<cfscript>
level = queryNew('howmany,name');
queryAddRow(level);
querySetCell(level, 'howmany','10');
querySetCell(level, 'name','Apples');
queryAddRow(level);
querySetCell(level, 'howmany','15');
querySetCell(level, 'name','Apples');
queryAddRow(level);
querySetCell(level, 'howmany','20');
querySetCell(level, 'name','Oranges');
</cfscript>
<cfdump var="#level#">
<cfchart show3d="true" format="flash" chartwidth="800"
chartheight="550">
<cfchartseries type="pie"
query="level"
itemcolumn="name"
valuecolumn="howmany">
</cfchartseries>
</cfchart>
<cfchart show3d="true" format="flash" chartheight="500"
chartwidth="500">
<cfchartseries type="bar"
query="level"
itemcolumn="name"
valuecolumn="howmany">
</cfchartseries>
</cfchart>
how do you like them apples? I don't like them apples!

Answer 1

I'm not aware that this is a confirmed bug. Bug or not, what
is commonly known is that cfchart uses just a fraction of the
functionality Coldfusion gets from the WebCharts engine. It is not
easy to tell when a deficiency of the tag is by design or when it
is a bug.
However, Coldfusion redeems itself a little. You can use its
webcharts engine to build your own custom charts, as MikerRoo has
hinted. If you're on Windows, all you need to do is to double-click
on
C:\CFusionMX7\charting\webcharts.bat. You should then get a
webcharts interface.
Choose a chart-type from the
Chart Gallery and press
OK. You can customize the chart by changing the values in
the
Property/Value table in the
Design tab. The engine registers such changes automatically
in the
Code View tab. For more on the classes in the code, have a
look at the
WebCharts3D
v5.0 Developer’s Guide.
Here is an example based on your query.
