    We have some customer requests every year to implement calculations relying on iteration to reach the final numbers, and - as always, we either say no or suggest custom applications.

    I hope we could be able to use for/while loops in expressions in the future, as it would give AF Analyses that extra functionality allowing us to solve "everything" OOTB. A combination of user-defined functions and looping would really make the analysis service "next level".

    I am using dark mode in most applications I use on a daily basis. Chrome with Dark Reader, Visual Studio, MS Teams, MS Office, etc. and it's really only PI System Explorer standing out with its white background.

    In addition to being able to call 3rd party code, it would be great to be able to create user-defined functions that you could reuse.

    The screenshot shows an expression I have, and I have to copy it 8-12 times in order to accommodate the number of product flows I need to calculate. This could easily have been done by creating a user-function with input parameters, and call that 8-12 times instead.

    I would appreciate a way to click F2 to open a popup window with a text editor for the analysis expression variables.

    It's very difficult to work with the current setup. After having done range checks and bad value checks on the input attributes, you've used the few visible lines and it starts becoming a mess when doing the actual expression logics.

    I've attached a screenshot to demonstrate!

    Any updates to this? It will be a pain if we can't communicate with AF through the SDK in our modern .NET applications.

    Any updates on this suggestion? Who's the PM for PI Server these days, since Steve left?

    Hi Steve. I obviously never got any notification last year that you had answered this, but this morning I got one.

    Anyways, as mentioned in the other comment here, the debug functionality seen in Excel is a good example of a user friendly feature. It shows expressions and by clicking Next... it evaluates each component one by one.

    The "Evaluate" functionality currently implemented is working fine, it gives you the answer to your expression. Normally I split expressions up in many variables, and design analyses to be easy to debug later. But it should be easier to debug expressions where everything is jammed into one variable as well. It's like in math class in school, it's not sufficient to show the end result of an equation, the teacher needs to see the intermediate steps to see you've done it correctly.

    You have rules implemented in the analysis evaluation engine, in order to determine the precedence of operators and functions, and I think it would be useful to be able to step through these evaluation steps. Here's a simplified example:

    Step 1 (original expression): TagAvg('tag1', 'y+6h', 't+6h') + TagAvg('tag2', 'y+6h', 't+6h')
    Step 2: TagAvg('tag1', '10-Dec-2020 06:00', '11-Dec-2020 06:00') + TagAvg('tag2', '10-Dec-2020 06:00', '11-Dec-2020 06:00')
    Step 3: 17 + 20
    Step 4: 37

    As you see, the "Evaluate" button only provides the answer in Step4, but I think it would be really useful to see Step2 and Step3 here as well. And, yes - you can see this today if you've written your analysis expression with a lot of variables, but often you come in and debug analyses other people have written, often with no comments or clues to what has been implemented. And you don't necessarily want to start breaking down someone's analyses into different variables either, which is what you need to do today if you want to debug the individual steps in order to see all intermediate values.

    I'm not suggesting one new feature here, this is a more general request to have better debugging capabilities. Have the software help you understand what's going on under the hood.

    The thing I suggested with an empty evaluation dialog is something I've seen in other systems, not sure which but perhaps Seeq. It can also be compared to the debugger console of Chrome developer tools. Once you have a debugging session open you can just type the name of the variable/expression you're interested in, directly in the console, and it will evaluate it immediately for you. You don't have to wait for a breakpoint to be hit, or to add it to watches. Just type it, hit Enter, and then you have it.

    Now if I had that available either as floating non-modal dialog or a console-style section at the bottom of the expression variable list, I could debug the individual parts of an advanced expression one by one.

    Intelligent debugging or assisted debugging. If you need more examples, send me an email and we'll set up a call.

    Most software we deal with on a daily basis allows pasting of images, so this is an important feature to include.
