Setting colors for item labels in JFreeChart (WaferMapRenderer)

Question

Hi,
first of all, sorry for posting a JFreeChart related posting on this forum, but I didn't get a solution right now (I even didn't find anything useful on the JFreeChart website/forum). Here's my question...
I'm trying to set the color for item labels in the legend but with no success.
Here's a code example:
final JFreeChart chart = ChartFactory.createWaferMapChart(
    "Wafer Map Demo",         // title
    dataset,                  // wafermapdataset
    PlotOrientation.VERTICAL, // vertical = notchdown
    true,                     // legend          
    true,                    // tooltips
    false
WaferMapPlot plot = (WaferMapPlot) chart.getPlot();
WaferMapRenderer renderer = new WaferMapRenderer();
renderer.setSeriesItemLabelPaint(0, Color.red);
renderer.setSeriesItemLabelPaint(1, Color.blue);
plot.setRenderer(renderer);The default behavior of the WaferMapRenderer is also strange because the item label as well as the item marker is painted black so you cannot distinguish different fields of the wafer map. Is this a bug or am I doing something wrong (or missing somehting)?
Any help would be greatly appreciated.
Thanks and best regards,

Your folder action script doesn't work because of one simple error:
set label index of every item of entire contents of processFolder to 7
Nowhere in your script is 'processFolder' defined, so AppleScript has no idea what you're trying to do.
Given that you (correctly) iterate through added_items, the correct format would be:
on adding folder items to this_folder after receiving added_items
  repeat with item_ in added_items
    tell application "Finder"
      set label index of item_ to 7
    end tell
  end repeat
end adding folder items to
In other words, this changes the label index of each item just added.
That should work provided you're dropping files into this folder. If you're dropping folders then this would set the label index of the folder itself, but not necessarily the items within that folder. For that you'd need to add a check to see if item_ was a folder and add code to handle folders.
Also note that this kind of folder action will only work on the folder itself - that is, if you have folder A that contains subfolder B, then dropping a file into subfolder B won't trigger the script and won't change that item's label. To do that you'd have to attach your folder action to subfolder B.
