The ternary plot is a specialized graph type and, as such, is not customizable to the degree that most other Origin graph types are.Use of this graph type assumes that your x,y, and z data add to unity. You can customize the axes in a minor way by choosing Format: Axes: x axis... (or y... or z...) and on the Tick Labels tab of the axis dialog box, enter a decimal figure of .01. This will allow you to display values as percentages.
FYI, If you enter other numbers into this box such as .3 or .0025, the axes values will change to reflect your chosen scale, but your data will not plot correctly.
