Description: Adding a diagram to a spreadsheeet with 2 colums and 50.000 rows makes Calc very slow. Editing or dragging the diagram takes several 10s. Saving the file takes about 30 s. Without the diagram Calc reacts normal, file save takes a few seconds. An example file is attached. Steps to Reproduce: see attached file Actual Results: Calc gets very slow as soon as a diagram is added Expected Results: response time should be less than 5 s Reproducible: Always User Profile Reset: No OpenGL enabled: Yes Additional Info: in some not easy to reproduce cases LO crashes when editing diagrams in sheets of similar structure and size

Still slow on macOS Version: 24.8.4.2 (AARCH64) / LibreOffice Community Build ID: bb3cfa12c7b1bf994ecc5649a80400d06cd71002 CPU threads: 8; OS: macOS 15.2; UI render: Skia/Raster; VCL: osx Locale: en-GB (en_GB.UTF-8); UI: en-US Calc: threaded The graph has 50,000 data points many of which overlap each other and redrawing it takes several seconds (Using an Apple M2 processor). It seems to be drawn in its entirety whenever any change to the data or graph is made. There would seem to be scope for optimising the redraw, e.g. by excluding hidden points from being rendered. When the same spreadsheet is opened in Excel changes to the data and graph happen much faster, with a barely-perceptible lag.
Still extremely slow on LinuxMint 21.3 with LO 24.8.4.2 (X86_64)
