Plot dialog: - "Units" (millimetres / inches) is the page setup's own unit: the offsets and the custom scale are shown in it, the stored ratio converts with it so the plotted result and the paper space's unit stay the same - "Custom: [paper] mm = [drawing] units" spells the picked scale in that unit and accepts a typed ratio, which selects the list's name for it or becomes a ratio entry of its own - "Hide paperspace objects" is the page setup's plot-hidden flag; it is no longer derived from the "Hidden Line" shade mode - "Save changes to layout" (paper layouts, on by default) writes the dialog into the layout when a plot is sent; previews never touch it - offsets are labelled in the page-setup unit and kept in millimetres in the file System variables (typeable, through SETVAR, listed by SETVAR ?): - PLOTOFFSET, PAPERUPDATE, PLOTROTMODE, PLOTTRANSPARENCYOVERRIDE and BACKGROUNDPLOT live with the persisted plot preferences: the plot origin counts from the printable corner unless PLOTOFFSET says the paper edge; a printer that does not list the sheet either warns or switches to its default sheet; transparency can be forced on or off; BACKGROUNDPLOT bit 1 is the dialog's background switch and bit 2 drives batch plots - CTAB and TILEMODE read and switch the current layout Tests cover every new control and variable; six new strings in all 21 locales; the Plot dialog grows to 940×690 for the two extra rows.
