Description: It appeared obvious that a line-chart with date-based values produced a bad graph. Tried installing v24.2.4, same result. Tried changing the date of one data point by one day (with six weeks between data points). This produced a large change in the plot, but also erroneous. See charts in attached .ODT and .PDF documents with further description. Steps to Reproduce: 1.Examine attached .odt and .pdf files that exhibit problem. 2. 3. Actual Results: Line-chart data points grapheded at wrong horizontal positions. Expected Results: Produce correct line-chart graph. Reproducible: Always User Profile Reset: Yes Additional Info: Version: 7.6.7.2 (AARCH64) / LibreOffice Community Build ID: dd47e4b30cb7dab30588d6c79c651f218165e3c5 CPU threads: 12; OS: Mac OS X 14.4.1; UI render: Skia/Metal; VCL: osx Locale: en-US (en_US.UTF-8); UI: en-US Calc: threaded

You are using line chart, with the major X units of years, and minor units of months. As with any chart type other than XY, this chart type divides the axis into months, and puts the points into these divisions evenly. Compare with histogram built on the same data. Use XY chart to treat the X axis as true numeric value. This is not a bug.
