Adding gridlines to the chart

On the X Axis (or Y Axis) tab:

  1. Check one or both of the Major Gridlines and Minor Gridlines check boxes. Use the Style buttons next to these check boxes to define the format of the gridlines.

    For example, this is an example of a chart with dark grey major gridlines and light grey minor gridlines specified for both the X and Y axes:
