About the Chart-Table Pretrain Data #13

Closed Coobiw closed 3 months ago

Coobiw commented 3 months ago

Hello, thanks for your great work! I'm curious about the re-plot ops of ChartQA and PlotQA to do chart-table-alignment pretrain stage. In my knowledge, PlotQA Dataset doesn't have the .csv file. So how do you get the table data? Looking forward to your reply!

Actually, plotQA and ChartQA all have their corrsponding tables, we use differenct API to re-plot them, and add arxiv table-chart pairs in chart-table-alignment pretrain stage. for plotqa(https://github.com/NiteshMethani/PlotQA/blob/master/PlotQA_Dataset.md), you should write code to extract table from annotations.
