DENEB - Problem with adding line to barchart

RvdH1212 — Mon, 18 Mar 2024 11:26:46 GMT

As mentioned in earlier messages I've just became aware of DENEB. It works all well, however when i try to add a line to my barchart, where the line is very sawy, instead of the expected smooth line. can someone see where this happens?

Thanks a lot!

Your sample data is a bit inconclusive - is this in general what you are looking for?

Hi Ibendlin,

Thanks for your response! Due to a lack of characters I had to reduce the example dataset. is there a posibility to provide more data? I cant do it in a regular message.

This is not exactly what i am looking for, the categories which are minus should be visible as minus and the categories in plus should be visible as plus. But the line is exactly how I want it.

So for 1 january:

1.212.714 and

-8.025.707

Where the negative amount (-8.025.707) is red and the plus amount (1.212.714) is green. This i wanted to achieve with the treshold function, which solved the problem. However, once adding the 7-days average line in the DENEB graph the line gets very sawy. Instead of the normal PowerBI Bar/Line chart, where it is smooth.

Thanks,

Richard
