Smooth lines

Is there any way to smooth lines on a line chart?

 

I'd like it to flow more like this one made in Excel, than the one below it made in PBI.

Re: Smooth lines

hi. there is not a way to do this in powerbi that i am aware of. 

 

I know that the smoothed line looks good but is it an accurate representation of the data?

This was a while back...any chance this is possible in new version?

Re: Smooth lines

Seems like a terrible idea anyway. In that example picture the curves make the lines go higher and lower than the actual data points they're connecting. So the graph is lying. It looks pretty but it's worse than useless for representing data. It's a good thing that we don't have this "feature".


Did I answer your question? Please mark it as a solution.

"..is it an accurate representation of the data?" - it can well be more accurate than showing only the measured points..

 

In case the data in question is anyway an estimate and contains error, representing absolute points instead of smooth lines indicating that "it is roughly like X" is totally and utterly warranted in my opinion. Also, for cases where you have continous phenomenon underneath (such as temperature...) but have only discontinuous measurements (say hourly), again, smoothing the lines to be continuous more truly represents the underlying distribution, of which the collected data is only a partly representing sample. I disagree with your stance for many a dataset of reality.

Re: Smooth lines

In case the smooth lines would go over or under the actual observed values, yes, wrong, but in case they remain within the observed boundaries, result may well represent reality better than discontinuous observations of a phenomenon. Think of temperature and hourly measurements of it. Cheers.

Re: Smooth lines

If you want to represent a "Gauss Bell", it is completely necessary to have smooth lines to understand the distribution.

That's because i think it is necessary to have the possibility to represent a smooth line chart.

Re: Smooth lines

Hi All,

 

The below visual offers the same functionality of smoothing as that in excel.
