[Read New File] Y-Axis Label [-] -
To add or modify the Y-axis (horizontal) label, click the Y-axis Label button. A pop-up text-window will appear to enter or modify the axis label. You may then select ok or Apply. In the former case, the label change will be registered immediately, but you will not see the graph change on the graph until next screen update. Selecting Apply forces an immediate screen redraw.
