When there are multiple columns on the x-axis, y-axis, or legend of a chart, you can easily reorder them. The order in which columns appear on the axis or legend is based on the sequence they are added. The first field serves as the primary sorting field for the chart. Adding another field places it after the first one on the axis label or legend. If you want to change the order, you can remove the fields and re-add them in the reverse order.
To reorder the axes, please follow these steps:
Select the Layout section in the sidebar.
Under Y-axis, drag and drop the column chips into your preferred order.
Click Update.
If you leave before selecting Update, your changes will not be saved.
