How Is the Mouse Used in Graph Applications?

The following (mouse) applications apply to the graphics window in STATISTICA:

OLE. Links or embeds foreign document files to STATISTICA documents by dragging them with the mouse pointer directly from Windows Explorer (across application windows) and dropping them onto STATISTICA Graphs.

Brushing. Highlights data points from the graph by clicking on them with the brushing tool.

Zoom in and Zoom out tools. Zooms in ("magnifies") or zooms out ("shrinks") respectively, the selected area of the graph.

Drawing tools. Adds rectangles, ovals (or circles), polylines and freehand drawings, arrows, etc. to a graph. Hold down the SHIFT key while you are dragging the mouse in order to make a square, squared rounded rectangle, circle, or quarter arc.

Resizing and moving. Resizes (drag on a "black selection square," ) or moves (drag the entire object, ) selected graph objects. For fine adjustments, see Controlling the mouse with the keyboard in graphs, below.

Editing polyline objects. Reshapes individual segments of the polyline drawing by dragging with the mouse on either the object area black selection squares or any of the black selection squares that mark the line segments. For fine adjustments, see Controlling the mouse with the keyboard in graphs, below.

Rotating text. You can interactively rotate custom text by selecting it in the graph and then dragging one of the object handles (small black squares) in the desired direction. For fine adjustments (1 degree movements), see Controlling the mouse with the keyboard in graphs, below.

Snap to Grid . Aligns drawing objects with the drawing grid, an invisible network of lines that covers the drawing area.

Graph Mapping Base. Click the Increase Font or Decrease Font toolbar buttons to change the value of the Graph Mapping Base by ±16%, respectively. Hold down the CTRL key while clicking either of these buttons to achieve a smaller (4%) increase or decrease in the mapping base.

Controlling the mouse with the keyboard in graphs. You can also emulate the mouse with the keyboard in order to move or resize an object by selecting the object, placing the mouse over the object, and then using the keyboard cursor keys to move or resize the object. Hold down the CTRL key for fine (1 pixel only) movements and press ENTER to complete the action.

Note that the mouse cursor changes to the appropriate tool to match the application for which it is being used. Press the ESC key to return the mouse to the default mode.

You can also use the mouse to interrupt a current action (e.g., redrawing of a graph; for more information, see Breaking, Stopping, or Interrupting the Current Action.
