PROC CAPABILITY: Positioning the Inset Using Coordinates

The CAPABILITY Procedure

Positioning the Inset Using Coordinates

You can also specify the position of the inset with coordinates: POSITION $\text{[math]}$ . The coordinates can be given in axis percent units (the default) or in axis data units.

Note:In this release of the CAPABILITY procedure, you cannot position insets by using coordinates when producing ODS Graphics output.

Data Unit Coordinates

[See CAPINS2 in the SAS/QC Sample Library]If you specify the DATA option immediately following the coordinates, the inset is positioned using axis data units. For example, the following statements place the bottom left corner of the inset at 12.5 on the horizontal axis and 10 on the vertical axis:

title 'Torsion Strength of Copper Wire';
proc capability data=Wire;
   histogram Strength;
   inset n / header   = 'Position=(12.5,10)'
             position = (12.5,10) data;
run;

The histogram is displayed in Figure 5.14.11. By default, the specified coordinates determine the position of the bottom left corner of the inset. You can change this reference point with the REFPOINT= option, as in the next example.

Output 5.14.11 Inset Positioned Using Data Unit Coordinates

Axis Percent Unit Coordinates

[See CAPINS2 in the SAS/QC Sample Library]If you do not use the DATA option, the inset is positioned using axis percent units. The coordinates of the bottom left corner of the display are $\text{[math]}$ , while the upper right corner is $\text{[math]}$ . For example, the following statements create a histogram with two insets, both positioned using coordinates in axis percent units:

title 'Torsion Strength of Copper Wire';
proc capability data=Wire;
   histogram Strength;
   inset min / position = (5,25)
               header   = 'Position=(5,25)'
               refpoint = tl;
   inset max / position = (95,95)
               header   = 'Position=(95,95)'
               refpoint = tr;
run;

The display is shown in Figure 5.14.12. Notice that the REFPOINT= option is used to determine which corner of the inset is to be placed at the coordinates specified with the POSITION= option. The first inset has REFPOINT=TL, so the top left corner of the inset is positioned 5% of the way across the horizontal axis and 25% of the way up the vertical axis. The second inset has REFPOINT=TR, so the top right corner of the inset is positioned 95% of the way across the horizontal axis and 95% of the way up the vertical axis. Note also that coordinates in axis percent units must be between 0 and 100.

Output 5.14.12 Inset Positioned Using Axis Percent Unit Coordinates
