Hi all,
I have the following codes in my page.
The style variable holds the custom style.
  <cfchart chartheight="450" chartwidth="550" gridlines="9"   yaxistitle="Score" scalefrom="20" scaleto="100" style="#style#"   format="png" >
         <cfchartseries query="variables.chart_query" type="scatter"   seriescolor="##000000" itemcolumn="MyItem" valuecolumn="MyScore"/>
     </cfchart>
Before I begin, please go to http://www.monteandjanicechan.com/chart_good.jpg.  This is how I want my report to come up.  On the x-axis, there will always be three items as long as at least one of them has values.  If an item does not have any values (i.e. 2010), there would not be a marker in the chart.
The problem occurs only when only one item has value.  Please see http://www.monteandjanicechan.com/chart_bad.jpg.  As you can see, 2008 and 2010 do not have any values; y-axis is now scaled from 0 to 100.  I have tried setting one of the items (ex. 2008) a value of 0 or something off the chart; it would scale according to this off-the-chart value and the 2009 value.  In short, I have to have at least two items with values between 20 and 100 in order for cfchart to scale from 20 to 100.
My question is, how can I correct the issue so that cfchart would ALWAYS scale from 20 to 100? I am running CF9.
Thanks in advance, Monte
