The Shortcut Menu

To display the shortcut menu, right-click on the data grid:



This command copies the selected range in text format into the clipboard. The channel name and unit will be written above the data values. A tab character (\t) is used to separate the columns and a new line character \n to separate the records.

If the range contains multiple selections, the bounding range will be calculated and used as the copy range.

The number of cells that will be copied is limited to 100000.

Freeze Columns/Unfreeze Columns

With this command the selected columns can be frozen. The frozen columns will be displayed with a gray background color at the left edge of the grid. The frozen columns will stay in their position when you scroll.

Mark Records as Deleted

This command marks the selected records as deleted. A new channel with the name ___Delete_XXX___ will be created. XXX stands for the dimension name. The channel values have the following meaning:

Value Meaning
0 Record not marked as deleted
1 Record marked as deleted

The values can be edited manually (set to 0 or 1).

To remove the selected records once and for all, choose Remove All Marked Cells. As long as the records and channels are not finally removed UniPlot will ignore the delete flag, e.g. the load function will also load the records that are marked as deleted.
