Include 'Transpose Array' method in the shortcut menu of a 2D array constant/control/indicator

Status: Completed

Available in LabVIEW 2015 and later

Similar to 'Insert' and 'Delete' methods, please include 'Transpose Array' method as shown below:

Requesting admin to make spelling correction in the title, instead of 'ocnstant' correct it to 'constant'.

We already have this option for graphs.

 

Many times arrays are processed by rows, suitable for autoindexing, but they should by presented to the user by colums for a more intuitive look.

 

Of course we probably need a visual indicator to show that the array is transposed to avoid confusion.

I was just saying that graphs have a right-click menu to transpose the 2D array data so the graph "looks right" depending on how the data is arranged in memory vs. the way we want to see it.

 

In my opinion, this is closely related to your current idea and offers a precedent, possibly lowering the threshold to implement it also for array containers. It has nothing to do with datatypes.

 

I strongly believe that an indication is needed. Any seasoned programmer knows that 2D arrays are autoindexed one row at a time, so if I have a 2D array diagram constant, I need to know at all times if it is displayed transposed in order to clearly see how the subsequent code will handle it. Otherwise we are flying blind and there are many more places where subtle bugs can hide.

As I read it, this is a suggestion to change the data, not simply the view of the data.  There would not be a "displayed transposed" state like the graphs can have.  Perhaps you are suggesting that there should be one (I think not for the code readability reasons you mentioned).

Well, since the suggestion wants it for constants, controls, and indicators, this seems like a can of worms. A data sink (indicator!) should not be able to change the data.

So, Christian, if we remove the "indicator" part and we are just changing the actual data in the array, what are your thoughts?

 

With that clarification, I find I would use this quite a bit.  Nothing like finding out that you typed in a large 2D array transposed and that you have to retype it (or copy the array make a VI to transpose, copy the new array data, and paste to your original array).

Well, don't look now, but you can delete rows and columns in indicators already.  But, these options only appear in the Edit-time RCM, not the runtime menu.  I did not suppose this would be any different.  No need to exclude indicators, just keep the item out of the runtime menu.

I agree with what Darin has mentioned in his reply.
