Created attachment 60261 [details] test document Create a new document. Use two solums of numbers (like: -1 3 2 0 -4 1 0 4 3 1 -3 2 1 5 4 2 -2 3 2 6 5 3 -1 4 3 7 6 4 0 5 4 8 7 5 1 6 5 9 8 6 2 7 6 10 9 7 3 8 7 11 10 8 4 9 8 12 11 9 5 10 9 13 12 10 6 11 10 14 13 11 7 12 11 15 14 12 8 13 12 16 ) Create a new chart -> Choose XY and Just lines. Now enable / diable curve smoothing. IS: Not cut when disabling curve smoothing, but cut when enabled... SHOULD: Not be cut... Win 7 x64: LibO 3.5.2; OO.org 2.4.1 Ubuntu 12.04 : LibO 3.5.2; 3.4.6
Most likely related to problems in the b-spline implementation. Related to Bug 47787
Created attachment 61465 [details] more samples, more simple I can reproduce the Effect, but IMHO not a bug. By definition such a "Stacked Series - Percent" chart only can show a range 0% ... 100%, what the smoothing will exceed. So that line parts can not be shown. The question is whether user needs suggest other solutions looking more elegant. Any suggestions (what show "correct" results, what ever that might mean)?
@Florian Did you ever see that working in a different way in other versions?
It looks the same in OO.org 2.3 @Rainer: Where is the 0% 100% range??
> @Rainer: Where is the 0% 100% range?? The Y-Axis (0% ... 100%). What, by the way, shows a workaround for some applications. If you define the Y-range manually from -10% ... 110% (for example), the gaps in the data series line disappear. So may be the final solution can be a more smart auto axis range calculation?
Created attachment 61499 [details] OpenOffice 2.3 screenshot @ Rainer: I still can't see the percentages anywhere! Please upload a screenshot too....
Change to earliest version ( OO.org 2.3)
Created attachment 61500 [details] New sample I marked yours as obsolete, because in your case it would not be a bug ( I agree -10 % is kind of silly ;) )
Back to the roots with new Summary. Indeed, Mew sample 2012-05-12 09:02 UTC, Florian Reisinger shows several cases, and I added a VeryNewSample.ods showing that also X-Axis is affected. Possibly unrelated: IMHO th percent-chart-problem is not directly related, because there an additional problem is that it's impossible to exceed axis-rang, and other questions need clarification, I will submit a separate bug for that. @Markus: Because your activity in Bug 47787 I think you also should proceed this one. Please change Status to ASSIGNED and add yourself to "Assigned To" if you accept this Bug or forward the Bug if it's not your turf
