Changes between Initial Version and Version 1 of Ticket #50585, comment 5

initial	v1
1		The Matrix plots (and others, too, I think) require you to select an appropriately sized region of cells in the spreadsheet. At least 2 rows/columns for MatrixXY and 3 for MatrixXYZ. The error described here results from not doing this and causes the crash in MatrixXY plots due to unexpected NULL data while trying to construct the sample plot view. MatrixXYZ doesn't actually crash due to an earlier fix committed to goffice [https://git.gnome.org/browse/goffice/commit/?id=813eabc31ed3cd7765312f78ae1cbb7c2085ebb9 here] and released with goffice 0.10.24.
