Column header as X/Y axis

When creating a line chart or radar chart etc it would be nice if you could use the column header as a X/Y-axis. Sometimes (especially when dealing with questionnaire data) its useful to be able to have multiple columns in one chart.

For example lets say you have a dataset with meta data (so you cant rotate the data-sheet) and have 10 questions that you would like to compare in a line chart. This is problematic as is in Power BI, since you cant use the column headers as X/Y-axis (dependent on which way you turn your graph).
