Graph Range

Each graph has its own range. The range is the amount of x and y that the graph window displays. By using the graph options dialog you can change the range of each graph window. The X minimum is the x coordinate that is at the left edge of the graph, the X maximum at the right edge, the Y maximum at the top edge, and the Y minimum at the bottom edge.

The default values of these parameters are (-10, 10) and (-10, 10). Since the width of the window is, by default, 355 pixels, this gives each pixels a width and height of about 0.056.

You may change these values by hand in this dialog box, or use the mouse in the graph window to zoom and pan.
