To configure a chart's subgroup axis

NOTE: The SubGroup Axis tab is called Sample Axis for P, Np, C, and U charts, and it is called Category Axis for the Histogram chart.

  1. If you have not already done so, insert a chart by selecting it from the Insert menu, or double-click an existing chart to access the chart's configuration panel.

  2. Select the SubGroup Axis tab (for P, Np, C, and U charts, select the Sample Axis tab; for the Histogram chart, select the Category Axis tab).

  3. If you want the axis to be hidden, clear the Show Axis check box.

  4. In the Orientation list box, select Bottom or Top to display the x-axis on either the bottom or the top of the chart (Bottom is the default).

  5. To change the color of the subgroup axis and its tick marks, click the Axis Color button and select a new color from the color palette.

  6. If you want a title to display on the subgroup axis, select the Show Title check box and enter the title in the Axis Title box. If you do not want a title, clear the Show Title check box.
