After you’ve added a reference line, band, or box, you can edit the definition. To do this, right-click the continuous axis and select Edit Reference Line, Band, or Box. If there are multiple reference lines, bands, or boxes in the view, use the additional menu to select the one you want to edit.
When you have multiple reference lines, bands, or boxes, you may want to change the order they are drawn in the view. To reorder a reference line, right-click the line and select Move to Front or Move to Back.
