It would appear that the BarChart only supports custom colors applied to all the bars for an entire column of data. This is referred to in the Data Format section of the documentation by the following paragraph.
http://code.google.com/apis/visualization/documentation/gallery/barchart.html The first column in the table should be a string, and represents the label of that group of bars. Any number of columns can follow, all numeric, *each representing the bars with the same color and relative position in each group.* The 'colors' option will get mapped to the numeric columns (i.e. colors[0] -> column[1], colors[1] -> column[2], etc.), but will be applied to all bars for that column. It would be helpful if they added support for overriding this behavior using custom cell properties similar to the way the Table visualization works to apply custom formatting for specific cells. -- You received this message because you are subscribed to the Google Groups "Google Visualization API" group.
