Chart Scale

Good morning,
  I am having a problem with chart scale...

We have a range of customers that are all the way from large ($300,000) per month to very small ($100) per month.

Executives look up sales and I have a form that is WORKING very well...the data is returned and the chart is attractive.  But the small customer charts look like there are "bumps" instead of and real data.

I'm sure I have to do something with the "scale to" section but can't figure it out.

My code is below.  I'm sure you can guess the results if a customer has $25 max in any one month. I need this resolved quickly...I'd like to go live for all executives without "explanations."  A perfect solution would be for them to have the option of scaling or not.

<cfchart>
xAxisTitle="Sales By Month - Last 4 Years"
yAxisTitle="Sales"
chartwidth="650"
showygridlines="yes"
scaleFrom="0"
scaleTo="300000"
gridlines="5"
show3d="yes">

<cfchartseries type="bar"
seriesLabel="Current Year" seriescolor="33FF33">
<cfchartData item="Jan" value="#chart_2004.Jan#">      
<cfchartData item="Feb" value="#chart_2004.Feb#">      
<cfchartData item="Mar" value="#chart_2004.Mar#">

Well I assume that you have a query that pulls the maximum amount correct?  It is hard to say with only the code you have shown....    Or at least you could write one?

Something like this :

<cfquery datasource="mydsn" name="GetMax">
SELECT MAX(amount) as maxvalue from mytable
</cfquery>

Then you could use the value in the scaleTo

<cfchart>
xAxisTitle="Sales By Month - Last 4 Years"
yAxisTitle="Sales"
chartwidth="650"
showygridlines="yes"
scaleFrom="0"
scaleTo="#GetMax.maxvalue#"
gridlines="5"
show3d="yes">
0
 
mrichmonCommented:
what about pulling the max amount and sending that as a variable to the scaleTo attribute?

So if you knew that the max amount for a customer was $25 then you would send $25 to the scaleTo field instead of hardcoding in the 300000
