The goal of this task is to classify chart images by type. Given the chart image, methods are expected to output one of the following 7 classes: Pie, Vertical Box, Horizontal box, Vertical bar, Horizontal bar, Line, and Scatter.



The evaluation metric will be the average per-class F-measure. Based on the class confusion matrix, we can compute the precision, recall, and F-measure for each class. The overall score is the average of each classes' F-measure.
