Created attachment 176375 [details] Kaplan - Meier survival curves Hello, I am a clinical researcher. I usually use libreoffice to visualize and work with medical figures. I have a problem with Kaplan-Meier curves like the attached example. These figures have some vertical marks on the curve, to identify censored patients. However, when I open the pdf with libreoffice, these marks are no longer on the survival curves. So the figure is no longer correct because no mark should be be outside the curves. Is it possible to avoid this happening? To reproduce the error you have to open the pdf with acrobat reader and libreoffice and compare.
Confirmed, the pdf import filter adds extra tic marks at each level of the curves when PDF is imported and opened into Draw. Note: the pdfium based insert filter does show the graphs correctly when inserted to document as image.

Created attachment 177413 [details] Another example of poor performance of libreoffice LibreOffice definitely performs poorly when there are many dots or lines in the image, which is almost always the case, so I will to switch to other alternatives. I am attaching another example so if anyone is ever interested in correcting these errors.

Mishandling of the tic marks on attachment 176375 [details] continue as in OP and comment 1, spurious tics extend off their chart curve lines. Or as compared to pdfium insert. While LO poppler/cairo import rendering of attachment 177413 [details] now matches pdfium based insertion. Or as viewed with Adobe Reader. So some improvement. =-testing-= Version: 26.2.0.0.beta1 (X86_64) Build ID: 620(Build:0) CPU threads: 28; OS: Windows 11 X86_64 (build 26200); UI render: Skia/Vulkan; VCL: win Locale: en-US (en_US); UI: en-US Calc: CL threaded
