Tools such as the Data Reader function on the active dataset in the active layer only.

To enable the use of the Data Reader tool on another dataset, first make sure that the correct layer is active (if there is more than one layer). To do so, simply double-click on the data plot that you are interested in. This opens the Plot Details for that data plot and automatically activates the layer that it is in (denoted by a depressed layer icon in the upper left corner of the graph window). Click OK to close out of Plot Details.

Finally, to activate the data plot, go to the Data menu and find it in the list of datasets located at the bottom. If it has a check mark next to it, it is already the active dataset for the active layer. Therefore you need not do anything at this point. If it does not have a check mark next to it, click on it to select it. The check mark is automatically moved to your newly activated dataset.

At this point, if you use the Data Reader tool, it will act on the newly activated dataset (data plot). If you wish to use the Data Reader tool on another dataset, make that dataset the active one by going through the same procedure.
