By default, no axis grids show. You can right click axis and uncheck Hide Grids to show grid lines or go to Axis dialog and check it on Grids tab.
And by default grids show behind your plot. You can set them to display in front of data plot by checking Grids on Top of Data context menu when right clicking axis or checking it on Display tab of the corresponding layer in Plot Details dialog.
