cfchart ignores my scalefrom value
- by Monte Chan
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
