See the "high DPI" tab on the window opened by the menu item [Preferences]. -Removed a menu item corresponding to an unimplemented function.
2/12/2023	7.0.0 -Modification for supporting Windows 11. -Changed compilers from Visual C# 2017 to 2022. -Changed prerequisites from .NET Framework 4.6.2 to 4.8 -Implemented functions to set the start- and end-points as well as step/division on the x-axis when one fits an orthogonal polynomial function to data by [Analyze]-[Fit Orthogonal Polynomial]. -Correction of wrong labels on a few windows. -Fixed a bug that arrows in the vector plot changes from graph to graph even if they have the same length. -Fixed a bug that the full plot scale search sometimes fails on pressing the right mouse button in the plot area.
1/23/2019	6.1.7 -Fixed a bug that the shortcut "Ctrl+T" was assigned both to the menu items [Data]-[Select Column] and [Window]-[Split]. Now "Ctrl+Q" is newly assigned to [Window]-[Split].
10/29/2018	6.1.6 -Fixed a bug that the "Edit expression" window does not appear after choosing the menu item [Edit]-[Expression].
9/28/2018	6.1.5 -Implemented options to draw x- and y-center axes at preferred positions. -Fixed a bug that the numbers are unexpectedly written on the x-center axis when the "1/x" or "log\|x\|" scales are chosen.
8/18/2018	6.1.4 -Implemented an option to replace hyphens in numberings and labels with minus signs. Uncheck the option in the "plot" tab on the "Preferences" window shown by [Help]-[Preferences] if one wants to leave hyphens as they are. -Fixed a serious bug that wrong results are returned when using the "make table" function on the "Convert data " window shown by [Analyze]-[Convert Data]. This bug was introduced in ver. 6.1.2. -Fixed a bug that the mouse cursor unexpectedly returns to normal while drawing a line/arrow.
