If you are editing the advanced XML for a chart that uses the JSChart module and you add an JSChart-unsupported property, Splunk simply ignores the unsupported property.
I would like to use among others also the "charting.fieldColors" param and it would be good if I could find out if it is supported by JSChart. In the http://docs.splunk.com/Documentation/Splunk/4.3/Developer/CustomChartingConfig-FontColorBrushPalette there is no reference to that. Where could I find a list of supported params?
