This menu is only active when a table is selected.
These commands are used to define the kind of data which is stored in the different columns of a table.
Define the selected column as abscissae for the plots. You can define more than one column as X-values in a tables, they will be referenced as X1, X2, etc.
In the case of 2D plots, this command defines the selected column as Y-values for the plots. In the case of 3D plots, Y columns can be used as the second abscissae.
In the case of 3D plots, Z columns will be used as plotted values.
Define the selected column for use as error bars width for abscissae.
Define the selected column for use as error bars for Y-values.
The selected column can be used in different ways in several plots (as X values, Y values, etc).
This command is used to define the global parameters of each column such as numeric format, column name, etc. See the corresponding dialog box section for more details.
This command is used to fill the selected column with the values resulting from a mathematical formula. See the corresponding dialog box section for more details.
When you fill a column (named for example 'C1') with the results of a formula (by using the Set Column Values... command), the values of the column are calculated only once when you define the formula. If your formula depends on values of another column (name for example 'C2'), the values of 'C1' are not updated if you modify the values in 'C2'. This command is used to recalculate the values of the selected column.
This command is used to fill the selected column with special values:
Removes all the values of the selected column
Adds a new column in the table. Whatever the selected column, the new one will be inserted at the right of the table after the left column.
Allows to define the number of columns in the table. Be carefull if you decrease the number of columns in a table, a number of columns will be removed and the data will be lost.
Allows to define the number of rows in the table. Be carefull if you decrease the number of rows in a table, a number of rows will be removed and the data will be lost.
Defines the active line in the selected table.
This command is used to convert a table into a matrix. It is mainly used to import data from files: the first step import data in a table, and the second one is the conversion of the table in a matrix.
