One way to do this is to use the expression column to create the tick marks
Specify the expression as “#-1”. Since the # column doesn’t have a length you have to specify that, set that to 25.
Create a text column (or numbers) and where you want major tick marks enter in values such as 0,6,12,18,24 and leave the rest blank.
Then in the axis setting, select X tick marks = Labels, use the ticks expression column as the locations and the text column as the labels.
