u Saved Matrix Data

Saving graph data to a matrix type variable saves it to a variable that has

lines and up to 6

columns, where

is the total number of samples in the saved data.

• If the maximum number of graphs are not on the display (less than three in the case of

Gph1, Gph2, Gph3; less than 2 in the case of Upper and Lower), data is not saved for the
unused graph(s). Data is saved in columns only for the displayed graph(s), and blank
columns are not included in the matrix for the unused graph(s).

• When the number of samples for Gph1, Gph2 and Gph3 (or Upper and Lower) are not the

same, matrix data is created in accordance with graph that has the greatest number of
samples. Unused cells for graphs that have fewer samples than the graph with the greatest
number of samples are filled with the data “Undef” (Undefined).

The following example shows how data is stored when there is data for Gph1 and Gph3 only,
and Gph1 has

number of samples.

Tip

• The time value is always stored as seconds.

• The storage capacity of the [Store Matrix] command is limited. If an error occurs, use [Store

Matrix] - [Select] to decrease the size of the range, or use [Mem] - [Store List] to store the data as
a list.
