If you import a dataset that has a few rows before the column headers, DataHero may ask you to select the correct row for column headers if it can't figure it out automatically.
Check the box next to the row you'd like to represent column headers. One thing to remember is that due to DataHero detecting the type, the column headers may not display as you expect until you check the box next to the possible header rows. If you don't see your headers, be sure to try a few rows to see if they magically appear.
Once you've found your header row, click to confirm and DataHero will place the correct row as your column headers.
Once you've selected the header row, any update of the file through live charts will automatically use the same row. Therefore, you only need to do this on the first import.
