[Read New File] Draw-Line [-] -
Often it is helpful to add a line to your graph, perhaps to better point at something you are annotating, or to show a critical region on your graph. Of course you could add or manipulate lines by editing a data-file. But, you can also add such lines interactively (visually) with this button. (The lines so-entered will be associated with the window or page, not the data.) To draw a line on your graph, click the Draw-Line button. Then click-once at the spot where you want the line to begin. Release, and move the mouse to the spot where you want the line to go to. Clicking a second time at the second point will produce the line on your graph. For extra help, you will see prompts in the text-window telling you what to do at each step of the process.
