This function will produce a bar plot to show the true positives (TP) versus the false negative (FN) for each target class. Both correct and incorrect classifications are color-coded to show the predicted class.
Inputs:
C - an integer matrix of the confusion data to plot, with ground truth labels in rows and predicted labels in columns
c_labels - a cell array of class labels, given in the same order as in C
cmap - [optional] a colormap matrix specifying colors to use in displaying each class from c_labels
max_y - [optional] integer maximum value for y axis in the produced plot
Outputs:
b_fig - a handle to the figure produced
