View Window

The Pisces View Window.

Only data whose projection lies within the current viewport is displayed. The viewport is the square [hmin, hmax] x [vmin, vmax] where hmin, hmax are the values of the text entry fields adjacent to the labels Hor and Ver.

Users may have an arbitrary number of view windows open at one time. If the cursor is in a view window, then the current coordinates of the cursor is tracked by Pisces and is displayed on that view window.

There are several options from a view window:

File Menu

Print whatever is currently on the view window, or dismiss (close) the window. We remark that the "Print" option under this menu creates a postscript version of the current contents of the view window without any frills. For configurable output (with the option to indicate axes labels, titles, and the current parameters of the current model), use the option Output->Postscript File available from the main panel.

Action Menu

Most of the interaction with Pisces occurs through this menu:

• Zoom In: The user must use the right mouse button to drag out a "rubber-band box" in the view window. If the user then selects Actions->Zoom In then the current viewport becomes region enclosed by the rubber-band box.
• Zoom Out: As above, the user may drag out a "rubber-band box" in the view window, and then select Actions->Zoom Out in order to shrink the current viewport into the region enclosed by the rubber-band box.
• Viewport->BBox: Upon selection of this action, Pisces will update the current bounding box to reflect the bounds of the current viewport.
• BBox->Viewport: Upon selection of this action, Pisces will update the current viewport to reflect the current bounding box.
• Erase This Window: Clear the contents of the view window. This option does not actually delete any data, so by reselecting Hor and Ver axes, the current data will be redisplayed.

Options Menu

Set display options such as the width of lines in the view window.
