--- Comment #5 from Charles Williams <[email protected]> --- 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. -- You are receiving this mail because: You are the assignee for the bug.
