Too Many Values. Not Showing All Data. - error for pie chart?
(edit after reading Greg_Deckler 's response. For sure this is new, because I'm still running the July version of the desktop (which is why I don't see it there))
The icon only shows up on the site, not the desktop.
This looks like a bug MiguelMartinez... The error goes away if you do not include the "unspecified" value (very small).
It would appear that the chart "rounds" out the number and doesn't show it, which is really odd behavior. I would think at the very least a pointer with "Unspecified" would show as a slice.
I don't know how you shaped your data but the screenshot below shows both ways I tried, and in both cases the site displayed the same behavior.
.
I think the issue may just be in the wording. I think it's trying to say "Some slices are too small to draw, so I didnt draw them". It didnt drop the data rows, it just physically can't draw a slice that small.
You can't really fix that, it cant draw smaller than 1 pixel. Some pie chart engines get around this by lumping multiple small slices into an 'other' slice. others list the values in the legend, even if there is no visible slice
I think you are right on the wording for the explanation just being off. I am having the same issue but when I enlarge the chart a little, a line with with the category name appears. And when enlarge the chart all the way, the missing data section shows up. Though even after it shows up, the warning does not disappear.
ColinM I agree, the wording is bad. But i can see the same behavior in xy-charts, which is really, really annoying. There single data dots are simply left out.
What I am saying is that this problem not only occurs in the pie chart, but in all types of charts, where much data has to be aggregated and displayed seperately.
Yep, that is exactly what I am seeing.
Very odd, thanks to both of you for taking the time to replicate it.
Now the real issue is:
1. needs to be a way to disable or adjust user facing error
2 Needs to be a way to adjust logic used and enable/disable/adjust threshold as needed per chart.
If I was graphing worker fatalities per days of year... just ignoring the 5 "statistically insignificant" deaths would be "Not OK" to say the least. (Or rapes per student body, positive cancer labs results, experimental vaccines that cured HIV, etc... not always OK to round to zero....)
This is becoming a large problem as we roll out PowerBI.Com in my firm.
This error is causing a trust issue with my users. Using the same Tabular models, same data, same filters - they never got this error in SharePoint PowerView.
Note my example. The error says that "too many month-year" values... But, it's filtered for 2015. It can't possibly be too many months for one chart. Data has been removed from this visual - it's essentialy lying at this point. Though, oddly enough it's the legend-value that is the problem.
I hope this is being fixed. It's becoming a big issue for my users that are PowerView pros wanting to make the transition to PowerBI.com.
