 ## Dataset Summary
-
-The dataset features instance segmentation masks for **400 real line chart images manually labeled 11 categories** by professionals. Images are collected from 5 different prfessions to increase the richfullness.
-In our paper we studedi two level of segmentations, **coarse-level** where we segment (spines, axis-labels, legend, lines, titles), 
-and **fine-level** where we have for each category an x and y subclasses (except legend and lines) and also each line is segmented seperatly.
