I am making a test request template for product engineers to fill out. The template will basically configure the product, and will prompt the user for nominal values and limits of each variable of interest. To make the process less time consuming, I would like the user to be able to manually (via some software) place three plots on a graph for each variable. The three plots would be the nominal, the upper limits, and the lower limits.

There is a Mask and Limit Express VI for LabVIEW that might be an option, but it appears as though it will be cumbersome, given many variables and complex profiles. We do not have DIAdem yet, but are considering the purchase. The template is in Excel, and the data might be acquired and analyzed with DASYLab, though it could be analyzed with LabVIEW.
