Trend: Logarithmic Scale
in some of our processes, we have pressure close to vacuum. in this case we need a logarithmic scale. until now, it's not possible to configure PI Vision trends with a logarithmic scale.
While we appreciate the interest the community has for this suggestion, we have decided to decline this item in favor of other high priority work the product needs. Thank you for your feedback, and please continue sharing suggestions for how we can improve PI Vision for you!
Is there already an update to this Topic? I saw there 3 other Feedback Posts regarding logarithmic scale (e.g. für xy-plots).Maybe you should merge them.

I agree, this would be very useful to have.
Our current workaround is to calculate the logarithm (or have it calculated via Unit of Measurement) and display that result. It works for displaying the value, but obviously it is then required to calculate back to the "real" value if you want to know the actual number.

yes, log scales would be very useful in machine life/CBM cases

It would be very helpful to have logarithmic scaling capabilities. Is there any plans to implement this as a feature in PI Vision?

I have the same problem as Frank, trying to monitor pressure in vacuum chambers down from atmospheric is an issue visually.
