Specification limits on SPC Chart

[Former Member]

Hi All,

I created a SPC chart with specification limits enabled. If user has provided lower spec limits without upper spec limits then it is taking the upper spec limit value as 0.0 by default. I would like to have limits to be one-sided.

For example:

An attribute should be at least 232,if its lower we have a problem. But there's no upper spec limit on it. The higher number we have the better.

If I put a very high number on the query, like 10000, that disturbs the Y-axis scale and shows Y-axis 0-10000, which does not show a good picture.So we need a way to enable only 1 spec limit, and keep other disabled as need.

Hoping to get a answer for this.

What happens when you make the upper and lower the same?

It is showing all points as deviating points to spec limits rule.
