OriginPro: How to label axis ticks in terms of pi

If you're plotting numeric values from 0-2pi for instance and we want the x-axis labels to be in terms of pi (0, pi/2, pi, 3pi/2, 2pi) then open up the book containing your dataset and add a column.

Then enter the values of 0, p/2, p, 3p/2, 2p in the rows of the new column.

Then go to the plot and double click on the x-axis then the Tick Labels tab.

Change the font to Symbol and the "type" to Tick-indexed datas.

In the Dataset box select the column containing the axis labels and click apply.
