Created attachment 176314 [details] Sample ODS file with examples When you create a scatter chart with smooth lines and the two first Y values are equal, then the chart skips the first value. When the first three Y values are equal, it skips the third, leaving a gap in the line (see attached file with examples). However, if you switch the chart to straight lines, all is ok (except for the fact that the lines are not smoothed). Steps to reproduce: 1) Open the attached sample file 2) In tab "Example 1" the chart uses straight lines, so all is ok 3) In tab "Example 2" the chart uses smooth lines and the two first Y values are equal, so the first is skipped 4) In tab "Example 3" the chart uses smooth lines and the three first Y values are equal, so a gap appears System info: Version: 7.2.2.2 / LibreOffice Community Build ID: 20(Build:2) CPU threads: 16; OS: Linux 5.13; UI render: default; VCL: kf5 (cairo+xcb) Locale: pt-BR (pt_BR.UTF-8); UI: en-US Ubuntu package version: 1:7.2.2-0ubuntu0.21.10.1 Calc: threaded
As you have the max value for Y to 1, seems the line it's out of the chart wall, changing the max value a bit up lets it be showed. In any case, looks like a bug.
