Data Analysis
18-33
On the left side of the information bar is a drop-down menu that displays the
symbolism and identifies the data source for each series currently linked. On the right
side is an Edit button that opens the Data Source Properties dialog box in which you can
set display names and data sources. Usually it is possible to unambiguously determine
what data sources a graph has, but sometimes you need to indicate what data source to
use, for example, when you plot a subrange of a data array. The information bar explains
that you need to do this as soon as you turn on data linking; then, you can open the Data
Source Properties dialog box to identify your data source(s).
