Menu view graphics.svg 绘图区界面

大部分的格局都配有 Menu view graphics.svg绘图区,且 GeoGebra 物件的图形皆会显示于绘图区。此外,绘图工具列位于视窗的上方,“复原”、“重复”按钮则在右上角。

绘图区

自订 Menu view graphics.svg绘图区

Menu view graphics.svg绘图区含有各种不同的格线与坐标轴(直角坐标、极坐标等)。更进一步资讯请参阅自订绘图区。您也可以根据自己的需求来调整 GeoGebra 界面的外观。

显示副 Menu view graphics.svg绘图区

检视功能表即可叫出副 Menu view graphics.svg绘图区。假如同时开启主、副 Menu view graphics.svg绘图区,此时只能在其中之一编辑物件(作用中的绘图区标题为粗体),且透过指令建立的物件会显示在该 Menu view graphics.svg绘图区。您可在物件的“属性”的“进阶”页中设定该物件要显示在哪个 Menu view graphics.svg绘图区


Creating Mathematical Objects

Constructions with the Mouse

Using the construction Tools available in the Graphics View Toolbar you can create geometric constructions in the Menu view graphics.svg Graphics View with the mouse. Select any construction tool from the Graphics View Toolbar and read the tooltip provided in the Menu view graphics.svg Graphics View in order to find out how to use the selected Tool.

备注: Any object you create in the Menu view graphics.svg Graphics View also has an algebraic representation in the Menu view algebra.svg Algebra View.
范例: Select the Mode circle2.svg Circle with Center through Point Tool and click in the Menu view algebra.svg Graphics View twice. The first click creates the center point while the second click creates a circle and a point on the circle.

Graphics View Toolbar

The Graphics View Toolbar provides a wide range of Tools that can be operated with the mouse and allow you to create the graphical representations of objects directly in the Menu view graphics.svg Graphics View. Every icon in the Toolbar represents a Toolbox that contains a selection of related construction Tools. In order to open a Toolbox, you need to click on the corresponding default Tool shown in the Graphics View Toolbar (GeoGebra Web and Tablet Apps) or on the small arrow in the lower right corner of the Toolbar icon (GeoGebra Desktop).

备注: The Tools of the Graphics View Toolbar are organized by the nature of resulting objects or the functionality of the Tools. You will find Tools that create different types of points in the Points Toolbox (default icon Mode point.svg) and Tools that allow you to apply geometric transformations in the Transformations Toolbox (default icon Mode mirroratline.svg).

Direct Input using the Input Bar

You can also create objects in the Menu view graphics.svg Graphics View by entering their algebraic representation or corresponding Commands into the Input Bar.

Note 提示: The Input Bar can be shown using the View Menu.


Modifying Mathematical Objects

The Mode move.svg Move Tool

After activating the Mode move.svg Move Tool you are able to move objects in the Menu view graphics.svg Graphics View by dragging them with the mouse.

备注: At the same time, their algebraic representations are dynamically updated in the Menu view graphics.svg Algebra View.

Copy & Paste

Via Keybord Shortcut Ctrl + C and Ctrl + V (Mac OS:Ctrl + C and Ctrl + V) you can Copy and Paste selected objects (except if they depend on the coordinate axes) into either the same or into another window.

备注: Copy and Paste will copy every ancestor of the selected objects but makes the non-selected objects invisible.
范例: If you copy objects depending on sliders into a new window, it will copy the slider (invisible) into the window, too.

The pasted object is fixed when you click on the Menu view graphics.svg Graphics View. If the copied object depends on at least one point then it can snap onto existing points when pasted (but only the point following the mouse pointer will do this).

Display of Mathematical Objects

Graphics View Style Bar

The Graphics View Style Bar contains buttons to

  • show / hide the Stylingbar graphicsview show or hide the axes.svg coordinate axes and a Stylingbar graphicsview show or hide the grid.svg grid (different kinds of grids in the GeoGebra Web and Tablet Apps)
  • go back to Stylingbar graphicsview standardview.svg default view
  • change the Stylingbar graphicsview point capturing.svg Point Capturing settings
  • open the Menu-options.svg Properties Dialog (GeoGebra Web and Tablet Apps)
  • display additional Stylingbar dots.svg Views in the GeoGebra window (GeoGebra Web and Tablet Apps)

Style Bar for Tools and Objects

Depending on the Tool or object you select, the buttons in the Style Bar adapt to your selection. Please see Style Bar Options for Tools and Objects for more information.
