Setting X/Y Intervals

The X/Y Interval menu only applies to non-reference axes.

Select Options ® X/Y interval to call up the X/Y Interval dialog box. This dialog box offers options for changing everything about the graph's appearance except the curve itself. To change the curve's appearance (color, line texture) see Setting Curve Attributes.

The X/Y Interval menu lets you modify the range of the axis scale. You can use the options in this menu to cut off the ends of the axes. For example, an x-axis with a range from -40 to +60 can be restricted to the range -10 to 30. When you request this restriction, SAP Statistics slices off the right and left sides of the display at x=-10 and x=30, respectively.

If the x-axis is a reference axis in your graph, the X/Y Interval menu only lets you change the y-axis. If your graph contains no reference axes, the X/Y Interval menu lets you change both.

Note that if you have turned Separate scaling mode on (by selecting Goto  ®  Display mode  ®  Separate scaling mode), the separately scaled axis will have different scaling on either side of the graph. In this case, the X/Y Interval menu presents a double set of options for the axis.

The X/Y Interval menu contains the following variables:

  • the upper limit for an axis
  • the lower limit for an axis
  • the ticks (number of gridlines) that span the axis

The number of gridlines includes the two outer sides of the graph. Hence for 10 ticks in the x-axis, vertical gridlines divide the graph into 9 stripes.

To change the values of these variables, click on the up or down arrows for each. The current value of the limit gets bigger or smaller as you click. You can also simply type in a new current value: click on the box where the current value is contained, delete the entry, and type in another.

If you have turned Separate scaling mode on (by selecting Goto  ®  Display mode  ®  Separate scaling mode), it is possible to request a different number of gridlines for the two sides of the y-axis. In this case, gridlines are drawn according to the scaling on the left side. On the right side, scale numbers appear, but do not necessarily correspond to the gridlines that are drawn.
