Two quick notes. First, the Cache Clearer code I released a long, long time ago (it uses the ColdFusion 8 Admin API to refresh items from the file cache) has been released as a 'formal' RIAForge project: http://cacheclearer.riaforge.org I added some user submitted updates, wrote a quick readme file, and packaged it up.
Second - a user asked me why the markerStyle "letter" would not work in a chart:
<cfchart>
<cfchartseries type="line" seriesColor="##FF0099"
markerStyle="letter">
<cfchartdata item="col1" value="20">
<cfchartdata item="col2" value="30">
<cfchartdata item="col3" value="40">
<cfchartdata item="col4" value="50">
<cfchartdata item="col5" value="60">
</cfchartseries>
</cfchart>
I checked the docs and nothing seemed wrong there. Running the code returned this error though: Marker style not supported: letter
I opened up the chart editor and noticed it listed letterx, not letter, as a marker style. Sure enough - adding "x" to the marker style fixed the issue.
I bumped up markerSize on the cfchart tag to make the markers more obvious.
