i am trying to match all not-words except ";;;" in a string, but i don't succeed. The not-words are unknown beforehand. Please see an example as follows:



Teststring: 

ab-cd ef;;;gh;ij;;;

Result:

abcdef;;;ghij;;;


Does anybody know a smart solution for that?



Thank you very much!

    "Not-words"? Could you clarify what a "not-word" is?

You can use the following regex to get all the parts of the string, you want to keep:



/w+(?:;{3})?/g


It matches any number of Word chars, followed by a non capturing Group matching 3 semi colons. This is optional.



You can then create the result by joining all the matches to a string.

  • Here you get 'what you want', not 'what you don't want', so Theres nothing that should be replaced.

What visual should I use to simply compare current year value vs last year in Power BI desktop

Image
0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?
