Hello,

I am trying to get a grouped bar plot with different colors for specific indexes within a group (not setting the colors for each whole group!). That is, for group 1 (of 3 groups for each index or x value ), I need some of them to be one color and others to be a different color. I've searched the question and answers on the board and I've seen 'looped' solutions for non-grouped bar plots but I can't figure out how to access the handle of a particular index of a group and manually set it's color.

My bar plot looks something like this: bar([x_idxs],[[y_vals group 1] [y_vals group 2] [y_vals group 3]]);

I've figured out how to change the color of any one of the groups to be what i want using 'set' and 'get' (and cdata or through other means), but how do i reference a particular index of a group?

I'm guessing other possible approaches include:

Plotting, one at a time (in a loop, using 'hold on'), the elements from each group - incrementally add (indexes of a group) to the bar plot with different color characteristics

otherwise stated - take element 1 from each of the groups and plot, take element 2 from each of the groups and plot, etc....

Or, plotting whole groups and then adding groups that have already been colored appropriately?

...but I can't get either of these to work.

Can anyone help me? Pleeeeeaaaaaaase!

Thanks, Kyle Stanhouse
