With respect to proc shewhart-pchart statement

Cingchih — Sat, 07 Mar 2020 03:13:49 GMT

I use two test-related statements, and the control chart is out of control.
Why don't the red words and red lines appear?
How do I adjust the grammar？
thank you for your response

PROC SHEWHART is a little weird compared to the more modern graphical procedures. Please try it with

ODS GRAPHICS OFF;

instead of with

ODS GRAPHICS ON;

If I turn off ods graphics, I will not be able to output large images. Or is there another way to overcome it?

Because I can't increase the size of text and numbers, I can only use ods graphics to output them as .tiff files, and then convert them to JPG files through LIGHTROOM. This text size is acceptable in this method.
If I setup ods graphics off, how do I set the width and height of the graphics and increase the size of the text and numbers, then please provide a method, thank you.

When I setup ODS GRAPHICS on the irchart statement (individual chart), the data points that exceed the control limits can be displayed in red. However, I can't succeed on the pchart.

I don't think this is true. Please give it a try.

The problem has been solved.

Just add testnmethod = standardize to the options after the pchart statement
