https://community.jmp.com/t5/Discussions/Two-required-y-responses-for-variability-chart/m-p/882539#M104652 <P>Hi,<BR />I would like to create a variability chart, but only with one column assigned to y, response. Sometimes that does work, sometimes JMP requires two columns to be assigned to y, response.<BR />Below two screen shots that illustrate the situation. Can anyone help why that happens and how to solve it?</P> <P><BR /><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Screenshot 2025-07-01 110927.png" style="width: 712px;"><img src="https://community.jmp.com/t5/image/serverpage/image-id/77616iBBF6644C94A8D005/image-size/large?v=v2&amp;px=999" role="button" title="Screenshot 2025-07-01 110927.png" alt="Screenshot 2025-07-01 110927.png" /></span><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Screenshot 2025-07-01 111159.png" style="width: 541px;"><img src="https://community.jmp.com/t5/image/serverpage/image-id/77615i9937563200E79855/image-size/large?v=v2&amp;px=999" role="button" title="Screenshot 2025-07-01 111159.png" alt="Screenshot 2025-07-01 111159.png" /></span></P> Tue, 01 Jul 2025 03:23:06 GMT JanH4 2025-07-01T03:23:06Z https://community.jmp.com/t5/Discussions/Two-required-y-responses-for-variability-chart/m-p/882539#M104652 <P>Hi,<BR />I would like to create a variability chart, but only with one column assigned to y, response.
