There are 5 main areas in the display, the menu bar at the top, the locator bar just below, the toolbar along the left-hand side of the display, the status bar at the bottom, and the drawing area where graphics are drawn. The following items describe the locator bar, the toolbar, and the status bar.
The toolbar runs along the left-hand side of the display, and provides functions to manipulate the axes scaling of active graphs, by scrolling and mouse powered zooms.
Click on Draw to freshen up the drawing area with the current set of graphs, parameters and active sets. Most operations perform an automatic redraw, this may be undesirable in the cases where the sets are large or there are several active graphs. By playing with the options in Graph/Draw options and using the Draw button, much of the tedium associated with slow redraw rates can be alleviated. If you feel something should have happened after performing an operation, press this button to force a draw operation to freshen up the display. If the X display being used does not do backing store, then Draw will give a clean picture if the graphics get damaged when overlaid by popups or other applications.
Zoom
Click on Autoscale to generate a default scaling for both the X and Y axes in the current graph.
Click on Expand to incrementally zoom in on the data.
Click on Shrink to incrementally zoom out from the data.
Click on Left to incrementally shift the axes to the left.
Click on Right to incrementally shift the axes to the right.
Click on Down to incrementally shift the axes down.
Click on Up to incrementally shift the axes up.
Using any of the buttons that affect the scale of the axes, it is likely that unpleasing tickmarks will result. By clicking on AutoT, the tick spacing will be set using the current autoscaling parameters (set in Graph/Autoscale).
Click on AutoO then click near a point in the set of interest to autoscale the current graph with respect to the selected set's bounding box.
Select a Zoom line used to scale the X axis of the current graph.
Select a Zoom line used to scale the Y axis of the current graph.
Autoscale the X axis only.
Autoscale the Y axis only.
Save the current graph's axes scales and tickmark settings, and prepare for a zoom. This function can be used to zoom in on an area of interest, then restore the previous graph scale.
Save the current graph's axes scales and tickmark settings for later retrieval. Use Pop to restore.
Restore the current graph's axes scale saved from the most recent use of Push.
Cycle allows the contents of the current graph's world stack to be displayed in stack order. The contents of the stack are unaffected.
Report on the current depth of the stack. Each graph has its own stack.
When cycling through the current graph's world stack, display the position in the stack.
