VI block can't fit in a single window

[varsha88]

Hello all,

I'm a newbie in Labview 2011. I have this VI file which has several while loops. But the blocks are scattered everywhere and not able to fit in a single window. How can i resize the the View so that I'm able to analyze each of the block in a single window pane.

Thanks.

Hi Varsha,

as hard as it is: delete the VI and recreate it from scratch keeping in mind all those points from LabVIEW StyleGuide, as is included in the LabVIEW help!

The VI's block diagram is huge. It's really huge. It's so huge I never have seen any block diagram that huge!

It makes LabVIEW going insane, it can't even show a navigation window(!):

- Someone moved all those functions over the structure seen behind.

- Someone named all those control with a generic name ("array", "boolean") with a appended number.

- Someone did hide most of those controls/indicators on the front panel.

- Someone choose to use locals instead of terminals (many terminals rest unwired on the block diagram).

Do you notice the scroll bars? They show the relation of the visible part of the blockdiagram in comparison with the non-visible parts...

Omg!

Start by using a single event structure to handle each and every one of those front panel Booleans and radio buttons. After you have done that and made the block diagram readable, we can address the local variables.

I tested this VI (VI Analyzer). Results:

The Diagram contains :

• 331 Structures
• 5624 Nodes
• 5004 Wire Sources
• 7070x32766 pixels
• 343 Coercion Dots
• 430 Write Local Variables/415 Read Local Variables
• 428 - Cyclomatic Complexity
• Half of Tests had failed.  

Read the LabVIEW help and see some examples to learn good pratices.   

Please, Delete this VI....

Tell your boss you need something like this to do your job.

I assumes you did not write this program yourself, but inherited it. Contact the original author.

Long story short, this VI is not maintainable and should be trashed. There is no way to verify correct operations and there is way too much duplicate code. I also suspect race conditions. The same functionality can probably be rewritten using less that 2% of the code. Start with some tutorials first.

All the program is,is a multi-tab FP where each page is selected programmatically in a menu-like system. All you need is a state machine the size of a postcard, not a gigantic monstrosity as you currently have.

LOL LabVIEW reported an "nonfatal Insanity" when I opened it up.  😄

At least it's wider on the bottom than the top and won't topple over!!
