To draw a line:

• Select the symbols you want on the right and left ends of the line.
• Move the mouse cursor to the first end point of the line. Either end will do.
• Press and hold the left mouse button.
• Drag the mouse cursor to the other end of the line. You will see a "rubber band" line from the first point.
• Release the mouse button. The program will draw a line between the two plotted points
• Note, if one (or both) of the symbols are the "arrow", the line will be drawn to the end of that side of the graph.

To change the scale of the line, click on the "Select Scale" pull-down field and change to the desired scale.

To paste the graph into a document (e.g. MS Word):

Click the "Copy to Clipboard" button. Then switch to the document and press Ctrl-v or Edit->Paste.

If access to the system clipboard is blocked the button changes to "NO ACCESS" and you have to use this procedure:

• With the graph displayed in your browser window, press the Ctrl-Alt-Shift-PrtSc key combination (that is, all at the same time).
• Go to your document and press Ctrl-v to paste an image of your browser window into the document.
• Use MS Word's picture crop and size adjustment features to get just the graph included at the right size:
  • Click on the graph and a "Picture Toolbar" should appear. If not, right-click the graph a select "Show Picture Toolbar".
  • Click the "Crop" button and move the lines around the picture until just the graph is showing.
  • Click the "Crop" button again to unselect it and move the lines around the picture until it is the right size.
