How to transpose a dataset using ignition expression?

Ignition

I have a dataset in custom property of a component and in another custom property I want to write the transpose of that dataset. Is it really possible with ignition expression?

Not natively, no. But you could do it with my unionAll(), columnInfo(), and forEach() functions in a fairly complex expression. But beware: this will almost certainly yield multiple different datatypes per column, which is not officially supported. (You can force it with java.lang.Object column types, but you will likely create problems elsewhere in Ignition.)
