https://community.jmp.com/t5/Discussions/Which-feature-to-use-to-analyze-material-changes-over-time/m-p/224900#M44689 <P>I have a material property that is measured at some irregular time intervals, usually whenever a new batch of material arrives. The measurement process gauge is known. I want to look at this property and identify changes in material performance and flag the vendor for improvements. Which feature in JMP will help me do this?</P><P>&nbsp;</P><P>Thanks,</P><P>Siva</P> Thu, 05 Sep 2019 18:43:16 GMT jsrk2084 2019-09-05T18:43:16Z https://community.jmp.com/t5/Discussions/Which-feature-to-use-to-analyze-material-changes-over-time/m-p/224900#M44689 <P>I have a material property that is measured at some irregular time intervals, usually whenever a new batch of material arrives.

The simplest visualization is a 'run chart:' plot the measurement versus the time and date.</P> <P>&nbsp;</P> <P>Related is the Analyze &gt; Quality &gt; Control Chart Builder provides a run chart but applies reasonable reference lines ('control limits') for evaluating changes.</P> <P>&nbsp;</P> <P>See Help &gt; Books for more information about these tools. Of course, continue to ask questions here!</P> Thu, 05 Sep 2019 18:52:24 GMT https://community.jmp.com/t5/Discussions/Which-feature-to-use-to-analyze-material-changes-over-time/m-p/224911#M44690 Mark_Bailey 2019-09-05T18:52:24Z
