cfchart with pie percents

[eliasobr]

Here's an example of the code....


<cfchart format="flash" labelformat="percent" >
<cfchartseries type="pie" datalabelstyle="value" query="qMsg2"
itemcolumn="realname" valuecolumn="times" serieslabel="Times"></cfchartseries>

</cfchart>



BTW, I work at a web house where we've employed pie charts with percents many
times. It is tied to the MX 7 upgrade. Any answers out there?

You need to post some actual data. This may not be a coldfusion problem at
all. For example, if the data is (33.3%, 33.3%, 33.4%), this could be
displayed as 33%, 33%, and 33% -- which does not add up to 100%.

OK, I understand what you're saying. I didn't present my message very clearly.
What I was trying to say is that it doesn't even come close to adding up to
100%; You'll have some that are 1200%, 1000%, 500%, etc. This was working
just fine before the CF 7 upgrade. Here is another example (which is with a
past company). [url]http://www.selfoodsales.com/subCobr/getStarted.cfm[/url]

I would show the current pages, but they are behind a firewall which I can't
control. Anyway, poing being, I (as well as other developers) had pie -
percents working just fine until the CF MX 7 upgrade, and now it is spitting
out these undesirable results. Your thoughts?

Sorry, I've had my own problems with CFChart. I guess I was hoping this was an
easy one. Anyway, it looks like you are sending values and expecting them to
be converted to percents? For example, on your example page, 2000 units is
about 33% and that looks to be about the size of the pie slice. So, you're
using labelFormat='Percent' and that used to work but doesn't now? If that is
true, then it sounds like a bug to me. You should file a bug report. I know
that the Webcharts3D engine supports $(colPercent) -- which does what you
probably want. You can use the Webcharts3D designer to create an XML style.
Set the 'Datalabels' property to 'pattern' and then use a pattern of
'$(colPercent)'. The wecharts designer is in your CF install directory usually
'C:\CFusionMX7\charting\webcharts.bat'. Good Luck. -- MikeR

Cool, that actually corrected the problem! The webcharts designer was easy to use, and was flexible enough to allow for customized attributes. Thanks a bunch. Cheers.
