Question

CFCHART - Percentages not right

  • January 21, 2012

I tried to set up a simple chart to display the results of a query, it works fine with labelformat="numbers", but if I change it to percent the results are odd, I get values above 100% on many of the pie slices. Anybody any idea?

Here's the code

<CFCHART

format="flash"

show3d="yes"

showlegend="yes"

chartheight="800"

chartwidth="900"

labelformat="percent"

showborder="true"

pieSliceStyle="sliced"

sortXAxis = "yes"

>

<cfchartseries

type="pie"

query="GetCountry"

valuecolumn="countrycounter"  itemcolumn="countrylong" />

Thanks

Mark

You are right. The chart attribute labelformat="percent" produces a pie chart with percentages that don't match. Indeed, many are several hundred percent! That could possibly be a bug.

To correct the problem, use the following chartseries attribute instead: datalabelstyle="pattern". That is

<CFCHART

format="flash"

show3d="yes"

showlegend="yes"

chartheight="800"

chartwidth="900"

showborder="true"

pieSliceStyle="sliced"

sortXAxis = "yes"

>

<cfchartseries

type="pie"

query="GetCountry"

datalabelstyle="pattern"

valuecolumn="countrycounter" 

itemcolumn="countrylong" />

</cfchart>

However, be aware that it is inadvisable to represent more than, say, a dozen or so data values on a pie chart. It can then get a bit crowded, especially if you decide to slice the pie, as you have done. In any case, 74 data points is way too much data to represent on a pie chart.

Thanks for the help, I could not find any info on datalabelstyle, and even after a search now that I have it I can't find anything

You are right, once I added this, its a little busy, trying to label every country

I think I might be best trying to label with a percentage and then mouse over for the country with percentage but I'm not sure if this can be done?

Right now when I mouse over the slice I get the country name with a total, but no percentage.

Is it possible to put the percentage and country etc into the mouse over label?

Then perhaps I can switch the regular label to just a percentage

Thanks!

The functionality you seek could be in some curious attribute combination in there somewhere. However, we could also play dumb, and create just what we need manually, and then do a mouseover. I was thinking of something like this

<cfquery name="getSum" dbtype="query">

    select sum(countrycounter) as sumCounter

    from GetCountry

</cfquery>

<cfquery name="getCountryPercentage" dbtype="query">

    select countrycounter*100/#getSum.sumCounter# as countryCounter, countrylong

    from GetCountry

</cfquery>

<CFCHART

format="flash"

show3d="yes"

showlegend="yes"

chartheight="800"

chartwidth="900"

showborder="true"

tipStyle = "mouseOver"        

pieSliceStyle="sliced"

sortXAxis = "yes"

>

<cfchartseries

type="pie"

query="getCountryPercentage"

valuecolumn="countrycounter" 

itemcolumn="countrylong" />

</cfchart>

Can you provide a repro case that includes the data (which is kinda important to your question).

Just mock a query up with queryNew() / queryAddColumn() etc.

Where possible, if you have a problem you should try to give us a repro case that is completely self-contained, and stand-alone (without any inferences as to how external systems like DB data might affect what you're seeing).  Obviously this is not always possible, but it definitely is in this case.

Cheers.

The query is pretty basic

<CFQUERY NAME="GetCountry" DATASOURCE="#datasource#">
SELECT countrylong,countrycounter
FROM countrylist
WHERE countrycounter > 0

Can you go back to my earlier post and read it.  You've not provided a repro case, you've just given me a dump of some data.  What am I supposed to do with that?

A repro case is some code that can be run and deomnstrates the problem (and then it can be tweaked etc to work out what the problem is).  SO go back and - please - do what I've asked you to do.  This is all part of learning how to solve your own problems (which in the long run is gonna be more helpful to you than just asking questions).

Trust me.
