New bug in Origin 2020.
Overlap(% Negative for Gap) is disabled for double y column plot.
==> Origin crashes.
Workaround: Don't drag diagonally. Drag horizontally or vertically.
Or right click legend and choose Properties.
Go to Frame tab to adjust Margins.
Select a plot in graph and Ctrl+C
Go to worksheet and select a cell, Ctrl+V
==> Plot data failed to be pasted.
E.g. fill column A with text, such as aa, bb.
In column B, set F(x) cell as A so it shows aa, bb.
Select aa and bb in column A and drag the bottom-right corner of bb downwards to fill with more rows with aa, bb, ...
==> Column B doesn't auto update to show more values.
Note: No such problem if column A is numbers.
No such problem if you manually enter more values in column A.
Workaround: Set column A as Text.
New but in Origin 2020.
E.g. create a 100 row worksheet.
Fill column A with row numbers.
In F(x) cell of column B, enter sum(diff(A))
==> Missing values show from row 51 on in column B
Fixed in Origin 2020b.
Choose Window: Script Window... menu.
Use run.section(file,ImportADO) instead
If user has user-defined import filter and drag and drop data file into Origin to import,
Select Filter dialog opens.
There is an Import Wizard button in the dialog to open it but it failed to open the dialog in Origin 2020.
