Why are there dates for the Grapher axis labels when there should be numbers?

This article provides steps for how to change an axis in Grapher that is showing date/time labels rather than numbers.

In Grapher, the first two columns of numeric data are automatically used for the X and Y values. If the data contains recognized date formats, the axes are automatically formatted for date labels. Most of the time in Grapher, when you change the X or Y columns, the axis formatting changes to numbers. If the axis keeps the date labels and you want to show numbers instead, the axis can be manually changed.  To do so:


  1. Click on the axis to select it. 
  2. In the Property Manager, click on the Labels tab.
  3. Click the next to the General section, if necessary.
  4. Uncheck the box next to the Use date/time format option. The axis will now use numeric labels for the ticks.
