You can create a timeline-chart in LO Calc like the following with error-bars: http://www.vertex42.com/ExcelArticles/create-a-timeline.html Even with pictures as shown in Figure 2. Info also here: https://www.officetimeline.com/excel-timeline and here: https://forum.openoffice.org/en/forum/viewtopic.php?f=9&t=32185 The only shortcomming is, that if I use a picture as Data Point Symbol, it is (in LO) transparent against the used error-bar. (Not transparent against a regular chart line!) It would be really nice, if the picture could be made "not transparent" against an error-bar too.

Maybe it is not a transparency problem, but a foreground/background problem.(Which is also not solveable with currently available user options!)
Sounds fair. NEW.
Bug is still present. No changes in bug behavior. Testsystem: LO 5.2.3.3 on Windows Vista
